in parts of southeast asia , tokay geckoes are regarded as harbingers of luck , good fortune , and fertility .
one way to determine whether a tokay gecko is healthy enough to adopt is to pick it up . a healthy gecko will dislike this and will bark or attempt to bite you , so be sure your hand is behind its head . if the gecko opens its mouth , it & apos ; s getting ready to bite . do everything you can to avoid getting bitten ; not only is the bite painful , but tokay geckos can lock on and refuse to let go once they sink their teeth in .
their skin is soft and granular with a kind of velvet feel to the touch . the tokay gecko has a cylindrical and stocky body with a rather flat top and a long characteristic semi - prehensile tail .

the tokay gecko ( gekko gecko ) is a nocturnal arboreal gecko , ranging from northeast india , bhutan , to nepal and bangladesh , throughout southeast asia , philippines to indonesia and western new guinea . its native habitat is rainforest trees and cliffs , and it also frequently adapts to rural human habitations , roaming walls and ceilings at night in search of insect prey . increasing urbanization is reducing its range .
this does not necessarily mean that the tokay is not a good terrarium subject , it just means that those people who like to handle their lizards on a regular basis may prefer a gecko species that is a bit more docile , such as a leopard gecko . however , if you are interested in maintaining a species that is large , colorful and interesting to observe , then a tokay may be right up your ally .
kept as pets in homes around the world , many asian cultures also consider tokay geckos to be good luck charms . these lizards are unfortunately frequent targets of poachers in the wild since tokay geckos are used in some medicinal remedies .
calls of the tokay gecko are used for communication , finding members of the opposite sex during the breeding season , and as a means of defense ( they emit a hissing or croaking noise when being attacked ) .
the tokay gecko is a solitary animal and they are only seen together in the mating season . the breeding season starts in the spring when daylight hours begin to increase and it lasts for 4 to 5 months .

don & apos ; t expect a cuddly pet if you choose a tokay gecko . they & apos ; re pretty to look at , but even those that have been in captivity for many years can become aggressive when provoked .
the tokay gecko has been available through the pet trade for decades and is one of the most popular gecko species among beginning hobbyists . because of the tokay ' s wicked temperament , it should not be the first choice for people who want to interact with their animals on a regular basis . however , i think that anyone interested in geckos should eventually try their hand at keeping these beautiful tough guys of the gecko world . as reptiles editor phil samuelson once put it ,
it ' s hard not to admire a small lizard with that much spunk !
when choosing a tokay gecko , look for one with a robust appearance . healthy tokays are bulky animals , and the spine , ribs or pelvic bones should not be visible . if the gecko is resting on the glass , look at the vent area and make sure there are no caked or smeared feces present . safely pick the gecko up and gently examine the lizard ' s body with your free hand , to make sure there are no abnormal bumps or depressions anywhere on the body , because they may indicate an infection or broken bones . when grabbing a tokay , place your hand directly ( and gently ) behind the gecko ' s head to avoid being bitten .

tokay geckos are known for being fierce and aggressive . they will fight until their last breath . they’re very much territorial . that’s why tokay geckos are said to be loners . they are better off alone , unlike leopard geckos which are more docile . tokays bite too hard so if you’re not used to holding tokay or your pet is untamed , make sure to use appropriate gloves .
their name arises from the call they make ; which sounds like
to - kay ! to - kay !
never house male tokay geckos together , and don & apos ; t house your gecko in your bedroom ; their barking may wake you up in the middle of the night . tokay geckos are also able to detach their tails to escape a predator .
the tokay geckoes are known for their quite unique appearance with a very attractive coloration in particular males which are more colorful than females .
demand for the tokay gecko has skyrocketed in recent years after online blogs , newspaper articles and wildlife traders extolled the consumption of the lizard ' s tongue and internal organs as a miracle cure for hiv , traffic southeast asia said in a report .
unlike the more
primitive
geckos ( such as leopard geckos ) that have movable eyelids , the tokay ' s eyes cannot close . instead , the tokay eye has a clear , protective spectacle , much like those of snakes . the gecko keeps the eye lens clean by frequently licking it . the eye has a vertical pupil that is indicative of this species ' nocturnal nature .
in indonesia , the harvest and export of wild - caught tokay geckos are subject to quotas . commercial breeding is allowed , and the government has given permission for six companies to export three million live captive - bred tokay geckos a year , specifically for the pet trade .
gecko’s eyes only see in black and white . because they are nocturnal , they have no need to distinguish colours . tokay geckos are aggressive , solitary animals . easily provoked , their powerful bite is a strong deterrent to other animals , including humans .
when a tokay gecko makes a hissing sound like air escaping out of a balloon or scream in a high pitched sound , this could mean that they are threatened . this is apparent especially to young tokay geckos which are not yet used to being handled . you must put them back on their terrarium before they become hysterical . they bite really hard so release them before they do so .
the tokay gecko is adapted to a primarily arboreal existence and possesses enlarged toe pads equipped with lamellae to aid in gripping . these adaptions allow the tokay gecko to climb virtually any surface with ease , including glass . the limbs are short and stocky , and the tail is semi - prehensile to aid in balance and maneuvering . the tail also serves as a means of defense and can be autotomized , or dropped , when the gecko feels threatened . a new tail will eventually grow back to replace the missing appendage . if the gecko feels threatened and cannot escape , it will gape its mouth , and may attempt to attack and bite a perceived aggressor . a bite can be a traumatic experience for both the lizard and the handler .
regardless of its reputation for fierceness , the tokay gecko ' s beauty , hardy nature and modest price have made it a popular
pet store
lizard . with the large numbers of imported specimens entering the united states every year , the tokay is one of the most frequently encountered gecko species in the pet market . many pet stores across the nation , even those that don ' t specialize in
exotic
animals , may have a terrarium with a few specimens for sale at any given time .
the strange eye of a tokay gecko can see only in black and white . the gecko hunts mainly by night , so has no great need for colour vision . photographed in bright light the gecko ' s vertical pupil has closed down to a narrow slit to prevent the high light intensity damaging its sensitive retina , but a series of small holes remains open . it is thought that light passes through these holes to be focused on the same area of the retina , allowing the gecko to see well even when it ' s dim .
( foy and oxford scientific films 1982 : 11 )
tokay geckoes are found in southeast asia and the malayan isles . they live in tropical rain forests , and are tree or cliff dwellers .
the tokay gecko , which has distinct orange - spotted , blue - grey skin , can grow up to 15 . 7 inches ( 40 centimeters ) in length . the reptiles feed on insects and worms , helping to regulate pests and maintain the ecosystem .
the gecko ' s call is responsible also for a slang name given to it by u . s . soldiers in
this gecko preys on dune - dwelling spiders and beetles . all water is obtained from condensed fog or from prey .
nearly all geckos have a voice , ranging from a small squeak to the deafening whistles of the african whistling gecko .
needless to say , any gecko this size would be a record - holder . the largest known gecko – the recently extinct delcourt’s giant gecko hoplodactylus delcourti ( generally thought to be endemic to new zealand , though this has been questioned ) – has / had a total length of c 60 cm , and the satria animal is more than twice as long .
as mentioned above , tokay geckos are not docile pets and may not be the best option for newbies . if you & apos ; re up to the task , you & apos ; ll want to choose a tokay gecko whose ribs and pelvic bones aren & apos ; t visible ; these are sturdy animals whose skin should be free of bumps , which may indicate a skin infection or a broken bone .
the tokay gecko is primarily a forest gecko with an arboreal lifestyle ( das , 2011 ) , but it is also closely associated with human settlements ( grismer , 2011 ) . it is a nocturnal species and has been documented to feed on insects , spiders , other geckos , and even small mammals and birds ( flower , 1899 ) . it tends to be a sit and wait forager , though it will be more active if prey abundance is high ( aowphol , 2006 ) . it is a highly territorial species and will not hesitate to bite when threatened . when tokay geckos bite , they clamp their jaws in earnest and will hold on for an extended period of time ( look at video below ) . the tokay gecko ' s defensive display involves gaping jaws which are often accompanied by warning ' barks ' . tokay geckos also moult to grow bigger , and shedding cycles are shorter if the surrounding temperature is higher ( chiu and maderson , 1980 ) .
tokay geckoes are insectivorous . in captivity , they usually feed on springtails , mealworms , cockroaches , crickets , grasshoppers , pink mice , and locusts .
pretty much like the roosters trying to outcry each other in the morning , tokay geckos do the same at dusk . it is rarely observable in captive conditions since there is not much threat of competition or threat . there may be some competition but can easily be managed or they have very little control over it so tokay geckos rarely do their distinctive vocalization . tokay geckos vocalize their “to - ko” or “to - kay” sound when declaring or marking their territory for the rest of tokay kingdom to know it is theirs . they do so to shout their might and often outcry the other barking tokay geckos in the area . this gesture secures them of territory for food supply and mate guarantee . it is also their means of courtship announcing their location to females . female tokay geckos can produce the same sound but they rarely do it . only matured tokay geckos cry this signature cry that they make , and until they could , male juveniles evade the bigger and more mature ones’ territories or at least stay out of their hunting range for the night .
while in captivity tokay geckos can live up to 18 years , but in the wild , their average lifespan is about 7 to 10 years .

although there are more than 20 species of geckos listed by the iucn , the tokay gecko is not among them . they are abundant in most parts of their range , but because of their use in chinese medicine , they have declined in south china , vietnam and thailand .
inspired by the patterns of millions of nanoscale setae on the tokay gecko’s toes , bioengineer jeffrey m . karp has received patents and awards for the biodegradable , biocompatible , elastic tissue adhesive . since 2008 , karp lab of harvard - mit science and technology and bwh has been perfecting this noninvasive alternative to stitches and sutures for closing and sealing wounds and incisions . also , this surgical tape will be able to release drugs to help tissues heal . for years many other scientists have mimiced the gecko toe hairs to make gecko tape and robots that can climb . one polymer scientist using carbon nanotubes remarked , “a gecko’s foot is like a perfect post - it . ”
the ears can be seen on the outside of the gecko as small holes on both sides of the head . it is possible to see straight through the head of these geckoes through their ears . tokay geckoes have a hearing range from about 300 hertz to 10 , 000 hertz .

an unfounded claim giving tokay geckoes the ability to cure aids also had a negative impact on the species . their natural habitat is also increasingly threatened by urbanization .
the tokay gecko ( gekko gecko ) is known for its extraordinary climbing ability [ 1 – 6 ] . the strong adhesion is mainly due to the van der waals force enhanced by the hierarchical adhesive system from the nanoscale to the macroscale . the gecko can also perform a fast transition from attachment to detachment or vice versa in around 50 ms [ 5 ] . extensive studies have been carried out to understand the strong adhesion and easy detaching mechanism of the gecko ' s adhesion system in order to fabricate biomimetic dry adhesives . these bioinspired materials have potential applications in wall - climbing robots [ 7 – 9 ] , adhesive medical skin patches [ 10 ] , adhesive clamps [ 11 ] , etc .
because tokay geckos aren’t listed under the convention on international trade in endangered species of wild fauna and flora ( cites ) , their international trade isn’t subject to regulation .
the vibrant and unusual - looking tokay gecko ( gekko gecko ) is a well - known , but poorly understood , species . heavy - bodied and nocturnal , these tropical animals have a reputation for being aggressive , hard to handle and apt to bite . however , they can be the ideal captive for a patient geckokeeper . they are fascinating to observe , and with a little invested time , they can be tamed into tractable little beasts .

the above work has addressed well the issues in the gecko ' s adhesion under static / quasi - static conditions . however , the previous models failed to explain the frictional adhesion feature , which was observed in the real gecko ' s movement . furthermore , the gecko detaches with digits peeled from the distalmost end to the proximal ( named active dh ) , and attaches with digits gripped towards the surface ( named dg ) while acting repeatedly on inverted surfaces . this behaviour cannot be fully understood based on previous models . argument exists in that if the gecko can lower the pull - off force by lowering the friction and vice versa , why are the active dh and dg needed ? therefore , it is necessary to understand the mechanical behaviour of the gecko ' s adhesive system from the dynamic scenario of the gecko ' s movement .
tokay geckos are vocal , making a unique croaking or barking noise to attract mates , are arboreal , and according to some myths , are said to bring good luck .
males are very territorial , and will attack other male tokays as well as other gecko species , as well as anything else in their territory . they are solitary and only meet during the mating season . females lay clutches of one or two hard shelled eggs which are guarded until they hatch . tokay geckos feed on

tokay geckos are not the simple lizards some herpkeepers may think they are . seemingly aware of their surroundings and circumstances , they have proven to be high - strung due to above - average intelligence . to me , tokay geckos are similar to reticulated pythons : known to be aggressive , they are alert , high - strung and challenging to keep .
in contrast to this , if a deceased specimen is found it is often considered a sign of bad luck . injuring or killing a tokay gecko is also considered bad luck in many areas throughout its range , and the species is a welcome guest in people ' s homes because it eats pest insects such as roaches .
tokay geckos aren & apos ; t as commonly seen as pets as leopard geckos , but they are just as interesting as their cousins . they are the second - largest kind of gecko and are known for their vibrant colors and spots . they are usually a blue - gray color with bright orange and blue spots .
temperament : it is ideal to keep just one gecko in a tank due to their territorial nature . it is never recommended to keep more than one male gecko in a single tank when housing them in groups . two or more males in one tank tend to fight and kill each other .
if you have a mature tokay gecko pet , it would make the same repeated sounds at random intervals within the day . a crackling sound followed by a “to - kay” sound could mean that they are looking for a mate . this strong sound they create can be heard from a distance to call for possible nearby mates .
geckos are one of the most successful lizards around today . from gekkonidae alone , nearly 1200 species have been described , and they range throughout subtropical and tropical regions , stretching even into temperate zones ( vitt & caldwell , 2009 ) . in singapore , at least 15 species of gecko have been recorded ( ng et al . , 2011 ) . among these , the tokay gecko is one of the largest and is also one of the most distinctive . this gecko is also the best known species in the group , and studies on it have contributed much to our knowledge of general reptile biology ( rosler , 2011 ) .

over the last several days a consortium of people interested in herpetology , weird animals , animal lore , and special effects have worked together to help resolve an incredible and bizarre ‘mystery’ * . people in indonesia ( and perhaps elsewhere in tropical asia ) are modifying live monitor lizards to make them look like gargantuan tokay geckos gekko gecko .
tokay geckos may be harvested from the wild in indonesia under a quota system . however , if they are farmed , they don’t fall under that quota system . any harvest of tokay geckos from the wild outside the quota system is illegal . note that the quota in indonesia for wild - caught tokay geckos stipulates that the animals are exported live , for pets , not kiln - dried . unfortunately , tokay geckos aren’t listed in the appendices of cites , and therefore international trade isn’t regulated . we strongly recommend the species be listed in appendix ii , which wouldn’t stop trade but would put in place a mechanism through which the trade could be monitored and regulated . to do so is in the interest of conservation and sustainable trade .

while it’s often argued that captive breeding relieves pressure on endangered species by providing an alternative source for trade , the report , adding up the numbers : an investigation into commercial breeding of tokay geckos in indonesia , demonstrates that the opposite is true . rather , it finds that wild - caught tokay geckos are regularly laundered through indonesia’s captive - breeding facilities on a massive scale .
because of their ready availability and low cost , the tokay is often the first gecko that many people purchase . unfortunately , many first - time owners are rudely awakened when the lizard that the pet store staff labeled
a good beginner ' s gecko
turns out to be an animal with a personality that is pure evil ! while its true that these lizards are easy to maintain , their willingness to bite any hand that dares enter their domain should exclude them from the
pet
lizard label .
the tokay gecko has a geographic distribution extending from eastern india , nepal , bangladesh , east to southern china and south - east asia , to the philippines . it has also been introduced into florida , hawaii , martinique in the west indies , and madagascar ( das , 2001 ) . it is unclear if the lizard is native to singapore , though it has been suggested that it probably is not ( flower , 1899 ) . this gecko is uncommon in singapore ( lim & lim , 1992 ) .

tokay geckos exhibit great variation in color in the wild , and are known to match their body color with the substrate they are on . the time of the day can also lighten and darken
in its natural range , the tokay is found from northeast india across to southern china , throughout the malay peninsula , the andamans , the philippines and throughout much of indonesia . feral populations have also become established in sections of southern florida , hawaii and the island of martinique . they adapt well to secondary , or disturbed , environments , especially around homes , buildings and other human structures . because of their close contact with humans , they have become the objects of many superstitious beliefs . in various sections of its native range , the tokay gecko is regarded as a messenger of omens , both good and bad . depending on the situation , a tokay ' s presence or vocalization can mean good luck and prosperity for a family or individual .
tokay gecko is often erroneously believed to be venomous . but , in truth its bite is not poisonous , even though it is quite painful . however , researches show them to carry various bacteria that can cause serious health problems . so , it is crucial to take care of the bite wound as soon as possible , especially if has penetrated the skin .
: geckos are lizards , and ( due to the structure of their vertebrae ) they are considered quite primitive on the evolutionary scale . geckos are small animals with a flattened appearance . tokay geckos are one of the larger species , measuring up to 40 cm in length . tokay males are larger and more colourful than the females . they all have large eyes covered by transparent scales that act as protective lenses . a gecko seen licking its eyes after a meal of insects is actually cleaning these scales . being a nocturnal species , they have slit pupils which , in dim light , expand to fill most of their eyes . all geckos have the ability to change colour , lighter by day and darker during the night . the tokay gecko does the reverse : the colour is dark grey with orange - red spots when in light surroundings , changing to light grey with bluish spots when they are in the dark .

another important feature of the tokay is its ability to cast off its tail in defense and later regenerate a new one . the cast off part will continue to move for several minutes , giving the gecko time to escape . it takes approximately three weeks for these geckoes to completely regenerate a new tail although it is usually never as long as the original tail .
as i stated before , these geckos are cantankerous , and when touched , a healthy tokay will gape its mouth and more than likely try to bite you . it may also let out a loud bark or scream in protest . if the gecko is limp , weak , or indifferent , pass on the animal and choose a different one . while it is true that there is the occasional specimen that does not seem to mind being handled , the vast majority of tokay geckos never really tame down enough to allow a handling session to be an enjoyable experience .
an important characteristic of the tokay gecko is its ability to cast off its tail in defense and regenerate a new one . the part of the tail that has been cast off will continue to move violently for several minutes until it slows down and stops , thus giving the gecko fair time to escape . the tail has several sections on it where it can break off at any given moment . it takes approximately three weeks for these geckoes to completely regenerate a new tail although it is usually never as long as the original tail .
from traffic’s southeast asia office , in malaysia , chris shepherd , coauthor of the report , explains that it’s low - profile species like tokay geckos that are often hardest hit by illegal , unsustainable trade .

tokays are one of the easiest species of gecko to keep and breed in captivity , but , ironically , most specimens offered for sale are wild - collected animals . by the time these geckos reach your neighborhood pet store , they have been captured , held in an exporter ' s facilities for days or weeks , shipped over oceans and possibly exposed to disease or parasites along the way . these stressful situations can cause a gecko to become more prone to infections or illness , so it is important to know what to look for when selecting a tokay .
the tokay gecko is the second largest gecko species , attaining lengths of about 11–20 inches ( 28–51 cm ) for males , and 7–19 inches ( 18–48 cm ) for females , with weights of only 150–400 grams ( 5 . 3–14 . 1 oz ) . they are distinctive in appearance , with a bluish or grayish body , sporting spots ranging from light yellow to bright red . the male is more brightly colored than the female . they have large eyes with a vertical slit pupil . eyes are brown to greenish brown and can be orange or yellow .
based on all of these bits of data , we seem to be seeing a lizard that has been kitted out to look like a giant tokay . it’s a lizard in some sort of ‘gecko suit’ . i must point out that this was my immediately favoured option . within a few seconds of watching the footage , and having ruled out the other contenders that came to mind ( giant salamander or genuine fat - headed giant gecko ) , i was immediately thinking “non - gekkotan lizard kitted out to look like a giant tokay” . and i’m hardly the first , or only , person to come up with this suggestion , as you can see if you look at the comments attached to the original video ( sorry , only available on facebook and not shared here ) .
tokay geckos have the ability to walk on different surfaces . a closer look at the gecko ' s foot reveals a structural hierarchy consisting of subdigital lamellae , setae and spatulas . it is postulated that the adhesion provided by the numerous spatulas works primarily through van der waals forces ( autumn et al . , 2002 ) , and capillary forces ( huber et al . , 2005 ) .
many geckos are relatively solitary , though bibron ' s gecko ( pachydactylus bibronii ) and some other species can reach very high densities and may share retreat sites . these geckos have
tokay geckos are not the easiest lizards to sex . they should have adequate conditioning first . the lizards tend to writhe and wiggle when restrained , so accurate sexing is difficult if one is unfamiliar with the process .


horned lizards are a genus ( phrynosoma ) of lizards which are the type genus of the subfamily phrynosomatinae .

the horned lizard has been affectionately called a " horny toad " , or " horned frog " , though they are not moist-skinned toads or frogs .

the common names come from the lizard 's flattened , rounded body and blunt snout , which make it resemble a toad or frog ( phrynosoma means " toad-bodied " ) , as well as its tendency , in common with larger true frogs and toads , to move sluggishly , making them easy to hand-catch ( such slow , undramatic movements may also avoid triggering attacks by predators , discussed later in this article ) .

they are totally adapted to desert areas .

the spines on its back and sides are made from modified reptile scales which prevent the water loss through the skin , whereas the horns on the heads are true horns ( i.e. they have a bony core ) .

of 15 species of horned lizards in north america , eight are native to the united states .

the largest-bodied and most widely distributed of the us species is the texas horned lizard .

horned lizards use a wide variety of means to avoid predation .

their coloration generally serves as camouflage .

when threatened , their first defense is to remain still to avoid detection .

if approached too closely , they generally run in short bursts and stop abruptly to confuse the predator 's visual acuity .

if this fails , they puff up their bodies to cause them to appear more horned and larger , so that they are more difficult to swallow .

at least eight species ( p. asio , p. cornutum , p. coronatum , p. ditmarsi , p. hernandesi , p. orbiculare , p. solare , and p. taurus ) are also able to squirt an aimed stream of blood from the corners of the eyes for a distance of up to 5 feet ( 1.5 m ) .

they do this by restricting the blood flow leaving the head , thereby increasing blood pressure and rupturing tiny vessels around the eyelids .

this not only confuses predators , but also the blood tastes foul to canine and feline predators .

it appears to have no effect against predatory birds .

only three closely related species ( p. mcallii , p. modestum , and p. platyrhinos ) are certainly known to be unable to squirt blood .

to avoid being picked up by the head or neck , a horned lizard ducks or elevates its head and orients its cranial horns straight up , or back .

if a predator tries to take it by the body , the lizard drives that side of its body down into the ground so the predator can not easily get its lower jaw underneath .

horned lizards are no exception to the general rule that lizards are not attracted to dead insects as food—the ants must be alive and moving for the lizard to show interest in them as prey . harvester ants can bite and have a potent venom , but apparently this has little effect on the esophagus or stomach of the lizard . however , when faced with swarming ants the lizard will make a hasty retreat , for these little invertebrates can kill an adult horned lizard .

the blood squirting defense mechanism of the horned lizard is the last ditch effort by the horned lizard to attempt to deter any predators that are shot . due to the fact that the horned lizard feeds primarily on ants and must dissolve the tough chitin layer of ants horned lizards end up with a large stomach and , in effect , lose mobility ( cooper 2010 ) . this hinders the ability of a horned lizard to escape and the horned lizard increasingly must rely on crypsis to help it survive predators . one thing to consider for horned lizards is escape theory . escape theory states that the probability of fleeing and flight initiation distance increase as predation risk increases and decrease when escape risk increases ( cooper 2010 ) . given that the cost of fleeing for a horned lizard is high , it is less likely to flee from a predator and instead rely on its defense mechanisms . the blood from its eyes is effective because of chemicals in the blood that is noxious to all dogs , wolves , and coyotes . in this way a horned lizard is able to deter a canine from attacking it . while such a mechanism does exist studies have shown that even though an organism may have well - developed crypsis the general rules of cost - benefit escape behavior do still apply ( cooper 2010 ) .

geographic distribution : this very rare horned lizard occurs in pine - oak woodland and xeric thorn - scrub of puebla and oaxaca , mexico . it may inhabit veracruz .
another behavior horned lizards exhibit is the ability to inflate their bodies until they look like spiny balloons . however , they most effectively avoid predators by simply holding still . horned lizards ' color patterns closely match the soil on which they live and they can eliminate their shadows by flattening against the ground . if forced to move , a horned lizard runs only a short distance , stopping unexpectedly . the horned lizard lies flat , blending into its surroundings , and the predator is left chasing nothing .
similar species : there are no other species of horned lizards in central and southern nevada . the short - horned lizard ( phrynosoma douglassii ) occurs in northern - most nevada , and it can be identified by very short horns on the head .

the texas horned lizard or
horny toad
is a flat - bodied and fierce - looking lizard . the head has numerous horns , all of which are prominent , with two central head spines being much longer than any of the others . this lizard is brownish with two rows of fringed scales along each side of the body . on most texas horned lizards , a light line can be seen extending from its head down the middle of its back . it is the only species of horned lizard to have dark brown stripes that radiate downward from the eyes and across the top of the head .
of course , sometimes camouflage , armour and squirting blood aren ' t enough , and a horned lizard gets eaten anyway . but even then they sometimes manage one last act of defiance : it ' s not unheard - of for a horned lizard to become lodged in the throat or stomach of a bird or snake , killing its attacker .

the technique works . a whip snake trying to get its mouth around a texas horned lizard may well give up , because it just can ' t fit the whole thing in .
the large , flat body surface of the horned lizard also works well as a solar collecting panel : at cooler temperatures , the lizard will orient its body to maximize the amount of exposure to the sun . when it gets too hot , the horned lizard will burrow into loose soil . initially , the lizard uses the scales on the front edge of its lower jaw to literally cut into the earth as it vibrates its head into the ground . then it will shake and shimmy its body into the soil until almost none of it is above the surface .
the body form and armor of the horned lizard cost it speed and mobil - ity , but they confer great advantages as well . small animals , such as snakes , have more difficulty with a horned lizard’s wide , thorny body than with a smooth , slender lizard . in fact , when confronted by a snake , a horned lizard will continually present the largest part of its body to the snake . some horned lizards are difficult to distinguish from rocks ; thus they avoid detection by would - be predators . in response to a threat , a horned lizard may play dead , or it may run away and then suddenly turn around to face its attacker , hissing or vibrating its tail in leaf litter . several species can rupture small capillaries around their eyes and squirt a bloody solution at would - be predators . these fluids , beyond coming as a surprise , can be irritating to the mucous membranes of some predators .
when a lizard crosses you and hit your leg . secondly , a water you are going to use to bath tmyour baby a lizard jump into and jump out . not dream but real life .
the most common horned lizard in the western deserts is aptly named the desert horned lizard ( phrynosoma platyrhinos ) consisting of two subspecies : the northern ( p . p . platyrhinos ) which inhabits the great basin desert , and the southern ( p . p . calidiarum ) which inhabits the sonoran and mojave deserts including a finger of the east coast of northern baja california .

populations of the texas horned lizard have disappeared in east and central texas , and are decreasing in north texas as well . a decline and disappearance of them in oklahoma and new mexico has been noted . other species of horned lizards throughout the southwest are also in trouble including the san diego coast horned lizard and the flat - tailed horned lizard . the primary cause for population decline is the loss of habitat by agricultural and urban conversion . other causes also have lead to declining populations including overharvesting for the pet trade and curio trade and the invasion of exotic species , particularly exotic ants which the lizards can not survive on and outcompete their preferred ant .

more recently , as the lizards’ habitat has shrunk and as imported fire ants have supplanted their favored prey , the numbers of horned lizards have declined drastically . in many regions where the little creatures once abounded , they are no longer seen . in texas , two of the three native species , the texas horned lizard and the mountain short - horned lizard , are now designated as threatened . jane manaster has written this book for a general audience , but she discusses all aspects of the lizards’ biology as well as the horned lizard’s place in the culture of the west . most of all , she has written it to attract attention to this little animal that deserves our respect and protection .

lizards are also used as clan animals in some native american cultures . tribes with lizard clans include the hopi ( whose lizard clan is named kuukutsngyam or kukuts - wungwa ) and the pueblo tribes of new mexico .
the broad , flattened body separates this lizard from the other three lizard species regularly documented in montana , and the range overlaps only with the common sagebrush lizard . the pygmy short - horned lizard has been reported from extreme southwestern montana , in the centennial valley , beaverhead county ( maxell et al . 2003 ) , but adults of this species are much smaller than greater short - horned lizards , the small horns on the back of the head project almost vertically rather than horizontally , and they lack the wide notch between the horns on the back of the head that gives the head of greater short - horned lizards a

appearance when viewed from above ( st . john 2002 ) .
snakes , and some birds such as roadrunners , need to swallow their prey whole . that means they have to get their mouth around the entire body . a horned lizard will not make it easy .

research by the texas parks and wildlife department on the chaparral wildlife management area , under the leadership of david synatske , have added to our knowledge of texas horned lizards ,
henke said . tpwd employees melisa montemayor and chip ruthven have been studying population dynamics and horned lizard movements for the past seven years .
most lizards scatter at the first sight of a human approaching , and horned ones are no exception .

the texas horned lizard can be distinguished from other species of horned lizards by the two very sharp spikes that protrude from the back of their head , two rows of fringed scales on their sides , dark brown to sooty - colored dorsal spots edged with lighter colors and a light - colored stripe down the middle of their back .
the horned lizard population is decreasing in north texas , so the fort worth zoo is partnering with the texas parks and wildlife department to breed and re - introduce them to nature . ( published tuesday , july 25 , 2017 )
in addition to texas , the lizard can also be found in southwestern missouri , kansas , much of the southwestern united states and mexico . it is against the law in texas to kill the horned lizard or to collect it and keep it as a pet . while horned lizards are probably the coolest looking reptiles in north america , unless you have a steady supply of harvester ants ( these lizards eat thousands of ants everyday ) they are virtually impossible to keep .

i dreamt of an indian lizard usually found in homes in india …dreamt of it in the home where i used to live as a child but the dream had me , my daughter and husband where i was asking my husband to get rid of the lizard and he tried but he did not follow my instructions so the lizard climbs the ceiling and then when he tries to get rid the lizard stops in the air for . 5 seconds and then falls on the bed , i rush away from the bed with my dot and the lizard is trying to run away from us making way from beneath the quilts and finally i woke up . .
humans and horned lizards have shared each other ' s company for thousands of years . this relationship is recorded from anasazi , hohokam , mogollon , and mimbres cultures through their use of horned lizard images on pottery , petroglyphs , effigy bowls , figures , and shells . hopi , navajo , papago , pima , tarahumara and zuni cultures portray horned lizards in their ceremonies and stories as symbols of strength . piman people believe horned lizards can cure them of a staying sickness by appealing to the lizard ' s strength and showing their respect to the animal . they formulate a cure by singing at a patient ' s side songs describing the lizards and their behaviors . a horned lizard fetish may be placed on an afflicted person ' s body during the songs . native mexican people also respect horned lizards attributing the words ,
don ' t tread on me ! i am the color of the earth and i hold the world ; therefore walk carefully , that you do not tread on me .
a mexican common name for horned lizards is
torito de la virgen
or the virgin ' s little bull . this name apparently was given to the lizards both because of their horns and because horned lizards are sacred to many people due to their blood squirting behaviors , otherwise considered weeping tears of blood .

there does not appear to be any one single reason for their statewide decline ,
he said .
most likely , it is a combination of these factors that is causing the decline in the population of the texas horned lizard .
a horned lizard will lap up its food with the tip of its sticky tongue . it does not chew the ants . instead , before swallowing , it wraps the ants in strands of thick mucus secreted by special cells at the back of its throat . this protects the lizard from the ants ' stings , allowing them to exploit a resource that most animals can ' t .
horned lizards are found throughout the sonoran desert region from near sea level up to 11 , 300 feet ( 3440 m ) . some species are widespread , such as the round - tailed and texas horned lizards which occur in several u . s . and mexican states , while the flat - tailed horned lizard ( p . mcalli ) is restricted to southwestern arizona , extreme southeastern california , a small part of northeastern baja california and the upper neck of northwestern sonora , mexico .
the diet of some horned lizards consists of specific insects , while other species are more catholic in their tastes . not only does p . solare prefer ants , it has a strong preference for harvester ants , which may make up to 90 percent of its diet . as diets go , ants are low return items because so much of their body consists of indigestible chitin . thus , the regal horned lizard must eat a great number of ants to meet its nutritional needs . this diet requires space , which is why the stomach of the regal horned lizard may represent up to 13 percent of its body mass .

jay snow took this series ( left to right , top to bottom ) of a red racer trying to eat a live southern desert horned lizard over a period of 44 minutes . the snake failed to swallow the lizard and crawled away . in the last picture you can see that the lizard lay prone for several minutes after the coachwhip left then took up to 15 minutes to clean the saliva off its face before slowly walking away , no doubt thankful for the row of horns behind its head . © jay snow
the coast horned lizard ( phrynosoma coronatum ) , which is found in coastal and cismontane california , crosses to the east side of the baja peninsula , actually making contact with the desert horned lizard in the vicinity of bahía de los angeles . the two live sympatrically for a distance along the east coast . as the coastal form has taken over the balance of the peninsula , it could also be considered a desert form since it does live in the deserts of baja right down to cabo san lucas .

the short - horned lizard is a small lizard species that lives in north america , in saskatchewan and alberta canada , through montana , utah , colorado , arizona , new mexico and into mexico through northeastern sonora , chihuahua , and durango . the creature is best known for having one of the weirdest defensive mechanisms out there , and that is the ability to shoot blood from its eyes !
to the uninitiated , their dragon - like appearance is quite formidable . the squat form and head armor has given rise to the name
horny toad ,
horned toad
and
horned lizards .
however , since there is a true toad with horns , it is best that we speak of this genus as the
horned lizards .
habitat destruction and ant destruction have placed several species of horned lizards in danger . after all , the first thing people do when they move into the desert is kill the pesky ants , thereby depriving horned lizards of their only dependable diet .
nevertheless , the coyote spots it . the predator pounces and holds the lizard down . then it gingerly nibbles – and immediately regrets it .
i had a dream about a lizard last night , and in my dream , i heard someone say that the lizard’s pituitary gland needed to be cut out . craziest dream ever . no clue as to what it may mean , but i clearly remember seeing this lizard , it having a so called “surgery , ” and it struggling afterwards but coming through . anyone have an idea as to what it may mean ?
i have been meditating or journeying for about 2 years now but in the past 6 months i have been seeing lizards , first was a komono dragon , and i could find information on him , but then i saw a black lizard with yellow spots , again i went in search of info and found general info on lizards . but yesterday i saw a horned lizard . i am wondering should i accept the information on all of these as one or is there specific knowledge to each type of lizard ? i am not able to find much on the horned lizard and find my self seeking the answer perhaps it is just not time to understand his meaning but if you have any thing that coould halp me on the diferent species of lizards i would really apreciate it . thank you in advance !

up to 10 species of horned lizards occur in the sonoran desert region , from the 2¾ inch ( 69 mm ) long round - tailed horned lizard ( p . modestum ) to the 5 inch ( 127 mm ) long texas horned lizard ( p . cornutum ) . with squat , flat , toad - like bodies ( phrynosoma means “toad - body” ) and thorn - like projections at the rear of their heads , horned lizards are easily distinguished from other lizards . the projections differ in size and arrangement from one species to another . along the sides of the body , fringe - like scales occur in one row , two parallel rows , or they may be absent . males have enlarged post - anal scales , and during the breeding season , a swollen tail base .

a stream of nasty - tasting blood squirts from the lizard ' s eyes , straight into the coyote ' s mouth . the coyote steps back , shaking its head from side to side in disgust . it retreats , wiping its muzzle , while the uninjured lizard skitters away to safety .
however , rattlesnakes don ' t chase . they wait for prey to come to them before biting , injecting venom and swallowing . so when a horned lizard encounters a rattlesnake , it runs for its life , safe in the knowledge that the snake will probably not follow .

most species of horned lizards lay eggs between may and august , with clutches ranging from 3 to 45 depending on species . even with such high numbers of eggs only around 2 from each clutch will reach sexual maturity . the short - horned lizard bears live young . this is considered an adaptation to living at higher elevations , where eggs may be at risk due to low temperatures , and egg development might be slowed considerably .
pygmy short - horned lizard ( phrynosoma douglasii ) the pygmy short - horned lizard is found in the pacific northwest from northern california through oregon and washington to british columbia , canada , and east through southeastern idaho . the species occurs in forest habitats and open plains with sagebrush at elevations from about 400 to 8 , 000 feet . phrynosoma douglasii can be distinguished from other horned lizards by its small adult size of only 2 - 3 inches , one rowof abdominal fringe scales , and head spines that are very short and reduced with a deep notch between them . their back scales are irregular in size and distribution and set in a rosette of smaller , keeled scaleswhile scales on their ventral ( belly ) side are smooth .

greater short - horned lizard ( phrynosoma hernandesi ) the greater short - horned lizard is a wide - ranging species ; it occurs from southern alberta and saskatchewan , canada , through montana , wyoming , utah , colorado , arizona , new mexico , texas , then through northeastern sonora , chihuahua , and durango , mexico . the species lives in short - grass communities of the northern great plains , in sagebrush and greasewood of the great basin , and on mountain hillsides and valleys with pine , juniper , aspen , and coniferous forests throughout its range . the species is found between 2 , 000 and 10 , 400 feet in elevation . phrynosoma hernandesi can be distinguished from other horned lizard species by the following : one rowof abdominal fringe scales , reduced central horns separated by a deep notch and slightly longer side horns , back scales are arranged in 6 - 8 rows . this species is the wyoming state reptile .
