stonogobiops is a genus of gobies native to the indian and pacific oceans .

this is one of the " shrimp goby " genera , the members of these genera being commensal with various species of shrimps .

stonogobiops

yasha hase shrimp goby ( stonogobiops yasha ) , the yellow rose goby ( stonogobiops nematodes ) and the dracula goby ( stonogobiops dracula ) .

stonogobiops is considered to be a relatively new genus as it wasn ' t raised to generic status until polunin and lubbock ( 1977 ) described stonogobiops dracula . in hoese and randall ( 1982 ) three additional species were added to the genus , followed by one species in iwata and hirata ( 1994 ) and finally the last species ( for now ) in the aforementioned yoshino and shimada ( 2001 ) , which brings the total number of stonogobiops species to six .
the most common member of the genus is the blackray shrimpgoby ( stonogobiops nematodes ) . the husbandry requirements of this species are very similar to the whiteray shrimpgoby .
stonogobiops pentafasciata is rarely encountered in the marine aquarium trade . presumably this is because of its limited ditribution around regular collection facilities . photos courtesy of jun harada .
the most sought after stonogobiops also happens to be the focus of this column . the whiteray or yasha hashe goby that is commonly referred to as scientifically un - described is actually named stonogobiops yasha . this species is most often found in pairs , but not always . it is , however , always found with the shrimp alpheus randalli .

while many of the fish listed are good tank mates for stonogobiops species , one should research each fish individually before adding it to the aquarium . some of the fish listed above are better left in the ocean or for advanced aquarists .
stonogobiops is one genus of a small group of genera often referred to as
shrimp - gobies
or
watchman gobies .
this is because these fish act as guardians over shrimp of the genus alpheus . this symbiotic relationship will be discussed in detail below .
predatory invertebrates such as brittle starfish from the genus ophiarachna should also be avoided . small gobies such as stonogobiops are an easy meal for these aggressive predators . likewise , anemones such as stichodactyla species should be avoided . all too often fish will fall victim to these anemones .
in addition to the teeth on the vomer , stonogobiops is noted to be one of the few genera of gobies that has a swim bladder . additionally , it differs from its closest relative , the genus cryptocentrus , by having a different pore pattern and reduction of sensory papillae on the head .
a near exact match to stonogobiops nematodes is s . xanthorhinica , or the yellowfaced shrimp goby . its common name is directly taken from the greek meaning of xanthorhinica .
xanthos
means yellow and
rhinos
refers to the snout . this goby , also only seen in pairs , relates with the shrimp alpheus bellulus .
it is difficult to assess what species of stonogobiops this is . this photo could easily be s . xanthorhinica , which differs only from s . nematodes with the short first dorsal spine . however , juvenile individuals of s . medon also have this same coloration . it isn ' t until s . medon ages into adulthood that it losses the black diagonal stripes . photo courtesy of jun harada .
la crevette et le gobie vivent dans le même trou . la crevette a une très mauvaise vue mais est un manœuvre puissamment outillé d ' une paire de pinces capables de remuer le sol pour creuser son refuge . le gobie lui voit clair avec ses grands yeux globuleux mais se montre naturellement peu équipé pour construire et d ' entretenir au quotidien un terrien qui régulièrement s ' effondre . la crevette glane de quoi se nourrir aux abords du terrier gardant toujours une antenne en contact avec le poisson . le gobie attend immobile scrutant l ' eau , quand un problème survient , ce dernier secoue la queue et se précipite au fond du terrier . la crevette perçoit le mouvement et ne tarde pas à s ' abriter elle aussi . une douzaine d ' espèces de gobies ont choisi de vivre ainsi avec des crevettes du genre alpheidae ou stonogobiops . chacun se trouve en usant de ses sens : le gobie utilise ses yeux pour reconnaître la crevette alors que cette dernière compte sur une détection chimio - olfactive pour trouver son partenaire . le lien de mon blog : urltoken

i hope that those of you that have a passive community tank will seek this fish and its shrimp associate out and give it a try ! they make fascinating pets .
the whiteray shrimpgoby ( stonigobiops sp . ) is a stunning fish that makes an fascinating addition to the reef aquarium . this individual was photographed off oshima island , japan , in 30 m of water .
when a predatory fish approaches , the goby will rapidly flick its tail , warning the shrimp of impending danger . if the goby flicks its tail once the shrimp may not respond , but if the goby executes a series of flicks the shrimp it will move quickly back into its burrow . if the predator comes within a critical distance , the goby will also dart ( headfirst ) into its hiding place . ( for a more extensive survey of shrimpgoby biology and behavior go to urltoken )
the yellownose shrimpgoby ( stonigobiops xanthorhinica ) and its snapping shrimp partner , alpheus randalli . this species is uncommon in the aquarium trade .
a captive whiteray shrimpgoby . note the slight differences in color pattern between this individual ( that was reportedly collected in the indian ocean ) and the individual from japan shown above .
in contrast , i have also had individuals that were very bold . one such individual “hooked - up” with its shrimp and was making feeding forays the second day after it had been introduced to the tank . but , this individual represents the exception , not the rule for this species .
of course , the whiteray is potential prey for piscivorous fishes , including large comets ( calloplesiops spp . ) , and may fall victim to fish - eating invertebrates , like carpet sea anemones ( stichodactyla spp . ) , crabs , and green brittle stars ( ophiarachna incrassata ) . ( it is more likely to be preyed upon when it is initially added to the aquarium and has yet to find a crustacean partner . )
a detailed shot of the head of the same individual . note the black patch of pigment on its
chin .
more than one whiteray shrimpgoby can be housed in the same tank . for example , i am currently keeping two of these gobies in a 105 gallon oceanic aquarium ( the footprint is 18 x 48 inches ) . in this reef aquarium , the snapping shrimp have constructed burrows on opposite ends of the aquarium . ( note : when i added the second goby - shrimp pair , i carefully introduced them to the end of the aquarium , opposite to where the other whiteray had established its burrow ) . because these gobies rarely move more than 10 inches from their burrows , i have yet to see them interact . because of their limited home ranges , i believe that i could get away with slipping another whiteray shrimpgoby into this reef tank .
placing the whiteray shrimpgoby tank in a low traffic area will also facilitate acclimation . for example , it is best not to house a whiteray shrimpgoby in an aquarium in the lobby of a dentist office , where there is a lot of human activity , including kids tapping on the glass . in this venue , the whiteray is likely to hide constantly , and as a result , it will not get enough to eat .
husbandry prerequisite is to feed this fish at least once a day . i feed my whiteray shrimpgobies twice a day . i feed frozen mysid shrimp , omega one flake food , and a wonderful food called cyclop - eeze® . the latter is a very nutritious food ( e . g . , high hufa and protein content ) , it remains in suspension longer , and my fish love it ! ( ask your
) . this gives smaller zooplanktivores more time to pick the food particles out of the water column . when you feed them , it is best to place the food in the out flow of a water pump , so that it moves through the water column like their natural prey .
that ends our examination of the fascinating whiteray shrimpgoby . i hope that those of you that have a passive community tank will seek this fish and its shrimp associate out and give it a try ! they make fascinating pets . happy fish watching !

* not all members of this genus have vomerine teeth . * * teeth are weakly attached and easily fall out .
in addition to the above genera , three additional genera have been noted to have vomerine teeth . unfortunately , i was unable to locate any additional information on these unnamed genera . therefore , i feel it is important to note the species which were initially reported to have vomerine teeth , but further research has proven they do not have vomerine teeth ( see below ) .
as may be seen in the above video , wormfish from the genus ptereleotris are often found as unwelcomed , yet ignored , guests sharing the burrow with the goby and shrimp . photo courtesy of jun harada .
the shrimp will collapse the entrance each night after all the occupants are inside . this serves as protection from animals that are able to slither into the burrow and capture their prey , such as myrichthys maculosus , the spotted snake eel . every morning the goby will burst through the collapsed entrance and the shrimp will begin the arduous task of rebuilding the entrance for the following day . once all the maintenance duties are completed , the shrimp will begin foraging for food and feeding .
there are additional benefits to the goby in this relationship . the female goby uses the burrow as a nesting place for her eggs . because of this , unfortunately , little is known about the mating ritual of this fish species . lastly , the shrimp has also been noted to use the smaller of its two claws in actions similar to cleaning as it works over the goby ' s dorsal fin and caudal fin , possibly cleaning the fish of parasites ( karplus et al , 1972 ) .
the goby always takes its food from the water column . while the fish hovers outside the burrow it is on constant watch for not only predators , but also prey . prey items typically consist of most anything fitting under the classification of zooplankton . the goby will dart up to one or two feet from the burrow in an attempt to capture prey , always quick to return back to the burrow ' s entrance immediately after capturing the food item .
provided the aquarium is large enough for anthias and direct feeding to the goby is administered .
most dottybacks will hunt and kill small gobies - pseudochromis fridmani and p . springeri are possible exceptions .
should be ok provided the aquarium is large enough for the rabbitfish and enough food reaches the goby .
many wrasses are best avoided . the most peaceful ones will be good choices .
it seems hobbyists are always looking for the next new thing to grasp their interest . symbiotic relationships are certainly one of those new elements . however , most aquarists tend to gravitate towards the clownfish - anemone relationship , which is more than a unique relationship itself . but for some hobbyists the clownfish is just too common to satisfy the desire for something novel . for those individuals the goby - shrimp relationship might just satisfy that hunger .

are a common sight in any aquarium store , with species oftentimes selling for not much more than the cost of a cheap damselfish . because of this , it might come as a surprise to learn that the half - dozen species that comprise the genus were completely unknown to science as recently as the late 1970’s ! the filamented shrimpgoby (
) , a particularly ubiquitous and affordable species in our hobby , was originally known from just a single specimen . so how do we explain this apparent contradiction between the rarity and monetary value of these fish ?
clearly , our knowledge of how to locate these fishes in the wild has improved drastically . unlike some of their close relatives ,
moderate depth ( 15 - 45m ) and in sheltered sandy or rubbley habitats , generally some distance away from coral reefs . many of the undescribed species which we’ll discuss in this review are known exclusively from deep , silty environments , where few divers venture . these fishes are in fact quite common in their preferred habitat—it just took a while to discover what that was .
is simple enough for aquarists ; they are small ( by shrimpgoby standards ) and typically have four black diagonal bars along the side of the body . the only exception common to aquarists is the yasha goby (
) , which has longitudinal red stripes . but the issue becomes murkier when discussing the obscure species
, which has a seemingly divergent color pattern—a single reflective - blue longitudinal stripe and similar markings across the cheeks .
what this phenotypically heterogeneous mix of species shares in common is the possession of a toothed bone ( the vomer ) in the roof of the mouth . amongst the enormous family gobiidae , only a handful of disparate groups share this feature , none of which bear close relations to
. to understand this properly , we’ll need to individually examine the coloration , ecology and biogeography of the many species in some detail .
the evocative name of this species can trace its origins back to its initially discovery in a seychelles lagoon back in the 1970’s . during a collecting dive , one of these diminutive fishes bit the finger of its collector , ichthyologist roger lubbock , drawing blood . this led to the discovery of the unique vomerine teeth , and the creation of a new genus to house this fish . the habitat it was found in was typical for the genus—a mix of sand and rubble at 15 - 40m .
is still poorly documented . in addition to the seychelles population , it can also be found in the maldives , from which specimens are regularly exported for the aquarium trade . identification is simple enough , as there are many useful characters to observe : 1 ) the first dorsal fin is short and clear , with a black marginal band posteriorly . 2 ) the thick bars along the body are red , and there are usually thin red bars placed between them . 3 ) there are two preopercular sensory pores . this last feature is only observable under magnification , but it is important , as it helps show the link to its sister species ,

in my experience , this species is somewhat delicate , with many specimens arriving in a lethargic and emaciated state and , soon after , perishing . this is apparently the result of poor collecting and handling on the part of maldivian fish distributors , and , given the inherent difficulty present in collecting these fish from their burrows , could be indicative of a narcotizing agent of some sort being administered . buy these fish with some caution , as specimen that refuse food are highly suspect .
is found a great distance away in the waters of southern japan . its distribution there appears to be limited to around okinawa eastward to the izu islands . it is apparently absent from the aquarium hobby , and is remarkably lacking from even the japanese market . its habitat is essentially identical to its sister species , and it shares with it a preference for living alongside the pistol shrimp
to identify this species , look for : 1 ) a series of five black bars along the body , with the first running diagonally through the eye to the bottom of the lower jaw . 2 ) a black bar across the tip of the fused pelvic fins . 3 ) a completely clear first dorsal fin , lacking any marginal coloration . 4 ) paired preopercular sensory pores , as in
this species nearly always has a white head anterior to the black stripe , which is typically yellow in related species . there are possible hybrids known ( presumably with

coral reefs , thousand of species , thousand of associations : but the relationship between little gobies and their shrimp partners is one of the most famous and better balanced , where everybody wins and nobody loses . a wonderful example of mutualistic symbiosis .
ew examples of symbiosis in the whole natural world show such a wonderful balance between giving and receiving like the mutual relationship existing between shrimp - gobies and their fellows alpheid shrimps .
shrimp - gobies are little fish widespread along tropical and sub - tropical seas worldwide , especially in sandy or rubble areas , where they share their ' house ' ( a burrow ) with small prawns , commonly called snapping - shrimps .
fig . 2 : a gold - barred shrimp goby amblyeleotris randalli displays his wonderful dorsal fin and eyespot . this feature can make a predator thinking that the fish is bigger of how he really is .
fig . 3 - 3b : a flag - tail shrimp - goby amblyeleotris yanoi sharing his burrow with the colorful shrimp alpheus randalli . this is an example of obligate relationship : this goby share his burrow only with this species of shrimp .
fig . 5 - 5b : not every shrimp - goby shows nice colors : this black - nape shrimp - goby cryptocentrus inexplicatus ' s color pattern makes a perfect camouflage with the sandy bottom . on the contrary , his fellow shrimp alpheus sp . displays a wonderful color especially on his legs .
fig . 6 : quite often the same burrow is inhabited by pairs of gobies and / or shimps . in this case a pair of alpheus ochrostriatus share the burrow with broad - banded shrimp - goby amblyeleotris periophthalma . it ' s almost impossible to distinguish the sex of the shrimps without bringing them out of the water , anyway sometimes even male - male or female - female pairs have been observed .
fig . 6b : quite often the same burrow is inhabited by pairs of gobies and / or shimps . in this case a pair of alpheus randalli share the burrow with a flag - tail shrimp - goby amblyeleotris yanoi . it ' s almost impossible to distinguish the sex of the shrimps without bringing them out of the water , anyway sometimes even male - male or female - female pairs have been observed .
when the pair it ' s formed , the process of building the burrow starts and , depending on the substrate and on the species of shrimp , could be short and branching , or long and deep , as it has been observed sometimes in some aquariums where the shrimp decided to build his house nearby to the glass .
the activity of the pair during the day is quite intense : the shrimp keep removing material from the burrow , enlarging the house and looking for food . the goby , aside from his watchman duties , is busy in catching his food ( mainly zooplankton ) . most gobies just lay down on the sand waiting , while some others hover on the top of the hole . the pair activity normally is reduced in the late afternoon , and in some cases during the night the shrimp closes the burrow entrance as a further protection against night predators .
more than 130 different goby species belonging to almost 20 genera are officially already described , but probably many other are still waiting to be discovered , especially in the coral triangle area ( indonesia , malaysia , philippines an papua new guinea ) . the symbiosis has been observed with up to 30 different species of pistol - shrimps , mainly of the genus alpheus .
fig . 7 : smart engineers , this steinitzi shrimp - goby amblyeleotris steinitzi and his little shrimp alpheus sp . have a reinforced entry , equipped with stones and pieces of coral that avoid the burrow entry ' s collapse .
fig . 8 : many species of shrimp - gobies have not been yet described officially , like this vanderhorstia sp . photographed in tulamben ( bali , indonesia )
fig . 8b : many species of shrimp - gobies have not been yet described officially , like this cryptocentrus sp . photographed in bunaken ( north sulawesi , indonesia )
fig . 8c : many species of shrimp - gobies have not been yet described officially , like this flag - fin shrimp - goby tomiyamichthyis sp . photographed in tulamben ( bali , indonesia )
shrimpgobies in the wild feed on zooplankton mainly . quite often a couple of gobies inhabits the same burrow , where the female lays the eggs . they are territorial fish even if the territory is not very large and in the same area it ' s possible to find several couples . they are not very good swimmer of course , but can be very fast .
all the shrimps living in association with a goby belong to the alpheidae family ( genera alpheus or synalpheus ) . they are even called
snapping shrimps
or
pistol shrimps
for their ability to produce a loud snapping sound using their larger claw . even if they are so small , they are one of the major sources of underwater noise .
fig . 9 : the genus vanderhorstia is relatively new and many species has been discovered in recent years . this twin - spotted shrimp - goby vanderhorstia ambanoro inhabits sandy areas of tropical indo - pacific .
fig . 10 : the rare mottled shrimp - goby tomiyamichtys oni with the common generalist shrimp alpheus randalli .
snapping shrimps are socially monogamous and territorial , with females performing all parental care . anyway , male and female partners share other duties like territorial defense , burrow construction , and foraging duties by returning food to the burrow , where both partners consume it .

scientists aim to describe a single ' tree of life ' that reflects the evolutionary relationships of living things . however , evolutionary relationships are a matter of ongoing discovery , and there are different opinions about how living things should be grouped and named . eol reflects these differences by supporting several different scientific ' classifications ' . some species have been named more than once . such duplicates are listed under synonyms . eol also provides support for common names which may vary across regions as well as languages .
eol content is automatically assembled from many different content providers . as a result , from time to time you may find pages on eol that are confusing .

bummer on the lost female . good to hear the other pair seems to be settling in . i ' m looks forward to checking these out soon ! good luck with them .
thanks for the luck , i need it ! i was not in a very good mood for a while after i found her . my odds would have been much better with 2 pairs . they were a noticeably larger pair as well . i chose the two larger ones to be a pair and the two smaller ones . a future mission i need to do soon as well is find a way to feed multiple times a day while gone . i am thinking of trying to make a doser type setup to meter in some live copepods every few hours . maybe just tiny pump in a fresh tigger cup each day would work and kick it on for a few seconds at a time . i would do a normal auto feeder and pellets ( if they would take them ) but now the jumping has me concerned . although maybe i can use a small funnel and airline to drop them through an opening the fish can ' t go the wrong way through .
sorry to hear about the jumper . . . funny how the fish that live on the bottom are always the ones that seem to make it out the top . the feeder into a funnel is a great idea ! hope you have luck with these !
here is a pic of the pair . they seemed to be a lot more relaxed and settled in last night . you can even see the tail of the shrimp in the bottom right corner .
thanks and i agree . this pair ( trio actually ) has been a dream of mine for a long time , something like 10 + years ago when i saw one single at a frag swap . it was pretty expensive then . i delayed too long and missed out on the 2nd part of the dream with a species first but they are awesome . beautiful fish and a cool relationship with the shrimp . i don ' t see how the rwu group won ' t sell a ton of these las they will be available year round instead of just a short collection season .
bad news update . i fed the pair monday and for about 2 hours left the towel off the top in one area , thereby exposing about a 1 / 4
gap on the normal glass cover . you guessed it , when i went back to plug in the filter i only saw 1 and my stomach sank . i don ' t know if these are just prone to jumping or if the tank is just too small for them . i had been intending to stop and buy some of the old school plastic presentation binders that i think i can slide onto the glass all the way around to fill the gap and prevent a jump but it ' s frustrating that it ' s almost like they hunt out openings . needless to say i will be stopping tonight but i have to make sure to keep everything covered 100 % of the time . the only silver lining is that the male of this pair jumped so i have 1 female and 1 male left . the male is now quite a bit larger than the female , not sure if that is good or bad . i will be putting them together this weekend , fingers crossed they do well . good days and bad days i guess .
good looking pair daniel ! i can ' t wait to join you in pursuit of these beauties . i hope the female eats soon . since these are wild caught , maybe them not having sand really stressed them . i think andy said it needed to be excavated gradually in order for them to adjust .
thanks . i agree on the wild / sand combo . the odd part though was that she was in this exact tank with barebottom prior to me adding the male and she was relaxed and eating well .
ken ( lrood ) is providing me a big bag of chaeto that i will be adding tomorrow . i figure that will help with any water quality and will also provide a good source of the tiggers that i load into it . i also just realized if she isn ' t back to eating prepared ( or maybe just instead of having him try to feed frozen food ) i will prepare a couple bottle of tigriopus and have him keep it in his fridge and add to the tank . the way the filtration is in this tank the face of the media is right there at that grate visible in the pics . with the relatively low flow and that placement , i think the copepods would end up staying in the tank until consumed . definitely a test run needs to be done tonight .
good luck daniel - hope that chaeto helps out . and be sure to enjoy that vacation ! ! !
step one is complete , finally ! they will now eat fertility frenzy out of the feeding tube . going to start trying to add pellets this weekend to see how they do with hopes i can add an autofeeder for daytime feeding . i am going to try to get them on pellets in an autofeeder ( and still fertility frenzy every night ) and then fattened up a little more before i start removing sand and a pipe in order to be able to see them better to allow easier monitoring . as of now i have to watch them on this cam feed in order to see them .
thanks kathy . the cam has been very useful . it ' s actually just an old iphone 4 running the manything app . you can do one camera for free and lots of people have old phones around . you can set it up to record on motion and can blank out any areas that you don ' t want it to record on . the only down side to the free is you can only view the last 4 hours of recording . if you pay you can get extra cams and extended viewing though . it gave me great peace of mind on the vacation ! i am happy with how the feeder is working . i just happened to make the horizontal part long enough that even when they move around in the tube and stir the food it doesn ' t float out into the tank . leaving the pumps off for an extended time and then hunting down all pieces of leftover food was becoming too time consuming . i also figured something like this was my only shot at feeding pellets in my autofeeder during the day with all the pumps on without polluting the tank .
thanks ken ! the vacation was awesome and the chaeto worked perfectly . one of the pistols is actually living inside the clump now . i can sometimes see his body moving around inside it and it occasionally comes out to grab food . i will have to be careful when pruning it .

dear song , specimens of flabellina rubrolineata from the nw pacific seem to have these brighter colours . apart from this , the colour pattern , and anatomy , appear to be identical to more typical southwestern pacific animals best wishes , bill rudman
hi bill , when we looked at these photos on the computer we noticed that this flabellina rubrolineata was laying eggs and you can actually see them being extruded from the body . we also noticed what may be a much smaller nudibranch in two of the photos but we are not sure whether it is a tiny flabellina rubrolineata that hasn ' t developed its colours yet . thought this may be of interest since it is a different colour form to the one we have previously sent in laying eggs .
distinguishing characteristics there are three mediterranean species of flabellina that resemble at first glance f . rubrolineata because of their violet general coloration ( f . affinis , f . pedata and f . ischitana ) , but the three red or purple longitudinal lines along the length of the animal are diagnostic for f . rubrolineata . besides , the mediterranean species have lamellate rhinophores instead of papillated .
dear ian , this is the ' typical ' colour form of flabellina rubrolineata , in the sense that it has the red lines that give it is name . some animals have no red lines and in others they appear as a series of red spots .
thanks for this photo of flabellina rubrolineata . although it appears to be feeding on the grey coral colony in the foreground it is a hydroid feeder so it is either just finished eating a hydroid colony or is our looking for one . best wishes , bill rudman
dear atsushi , flabellina rubrolineata is somewhat variable in colour . sometimes the red lines are broken or absent , and while in some animals such as yours , the skin is dusted with white , in others there may be no sign of white . best wishes , bill rudman .
hi bill , we found flabellina rubrolineata mating at the weekend . couldn ' t see any records of them mating on the forum list so thought this might be of interest . again because they curl up so much it is diificult to get a clear shot of it all happening .
dear bill , concerning your comment about the egg mass in des paroz ' s message , here is a photo where you can see the egg mass of flabellina rubrolineata more clearly . it was taken at ninepin island , hong kong . 15m depth . december 2000 . thank you leslie
this is flabellina rubrolineata . as its name suggests it usually has red longitudinal lines on its body , one down the centre of its back and one down each side of the body just below the cerata , but these lines can sometimes be broken , or in this case totally absent . . . bill rudman
hello bill , i was wondering if you could confirm the identity of this nudibranch for me please . is it a flabellina rubrolineata ? there were a number of these on the one bryozoan . this is the same bryozoan , pleurotoichus clathratus that i normally find the okenia hallucigenia on so at first i thought that it was another form of okenia . after some research and looking at the numerous colour variations for the flabellina rubrolineata shown on your site i think that it may well be one . i realise that they feed on hydroids and that it is possibly just a coincidence that its on the same bryozoan food source for the okenia .
hi bill , we found this flabellina rubrolineata laying eggs at the weekend . we often see them laying eggs during winter but it is difficult to get a decent photo showing what ' s happening because they tend to curl up and the growth that we find them on is so light that any water movement makes the whole thing sway like mad .
the ' typical ' colour form of flabellina rubrolineata , is the red lines that gives it is name . some animals have no red lines and in others they appear as a series of red spots . in this species , in comparison to conspecifics , the rhinophore club is papillate , but there are papillae only on the posterior side of the rhinophores .
thanks leslie , it ' s nice to get such quick feedback . i wasn ' t even sure that the egg mass in des ' photo actualy belonged to f . rubrolineata . cheers , bill rudman
i have included a small uncropped version of your whole photo to show what heaven your animal was living in . a huge ' forest ' of hydroids to eat , and not another flabellina in sight ! best wishes , bill rudman
hi bill , i was very excited to find these as aeolids were not so common in kavieng . i think they are both flabellina rubrolineata . the first image was taken on a wall , the second on a reef . the first was solitary , and on a sponge , while the second was with several other specimens and on hydroids and tunicates . dive sites : near kavieng , papua new guinea , july 2001 . depth : 15 meters length : 15mm photographs : marli wakeling
hi bill , i think this might be a flabellina . please can you help with the id locality : sodwana bay , south africa , indian ocean coast . depth : 13 m . length : 15 mm . 19 january 2006 . coral reef . photographer : colin ogden
hi bill it may not be scientifically relevant , but i think this photo is very cool ! this species of flabellina is common in the shallow reef areas here in timor and we found this individual just beginning to lay eggs . it seemed that it was using its posterior foot to direct the eggs onto a hydroid branch .
dear des , yes this is f . rubrolineata . it seems to be a tropical species with a permanent population in new south wales . in the upper photo i think you can see an orange egg mass beside the slug . it would be worth checking next time you see this species if you can find what its egg mass looks like .

the body of this aeolid is translucent white with patches of opaque white and a thin purple medial line running the length of the notum . two other lines run down the sides of the body . the cerata are translucent with opaque white subapically and purple , shading to white , at there tips . the digestive gland is visible through the cerata and is usually tan although the tissue of the cerata may be yellow in some animals . (
is a rare species on maui known from only four animals found in moderately protected to moderately exposed locations . their habitats ranged from rocky areas at 15 m ( 50 ft ) to
beds at 32 m ( 105 ft ) . it may be more common on oahu . it probably feeds on a yellow hydroid .
maui , molokai and oahu : widely distributed in the indo - pacific ; introduced to the mediterranean .
first recorded in hawaii from off makena , maui by pf on june 7 , 1994 . the name means
red - lined .
lars snitker : found by tiffany winn ; reef ' s end , molokini islet , maui ; dec . 28 , 2011 .
the yellow pigment in the cerata of some oahu animals seems to be in the tissue rather than the digestive gland . however , it closely matches the hue of at least one of the hydroids it eats . (

the general body color is translucent pinkish white . varying amounts of opaque white may be present on the sides of the body and notum
three purple or reddish longitudinal lines extend from the head to the posterior limit of the tail . the longitudinal lines can be broken into bars .
the coloration is variable , even within a population of a single locality . . .
three purple or reddish longitudinal lines extend from the head to the posterior limit of the tail .
- one of these is middorsal and extends from the anterior border of the head to the tail .
the rhinophores are elongate with an acute apex . the posterior surface is ornamented with approximately 100 elongate papillae . the anterior face of the rhinophores is the same color as the body . their posterior surface , where the papillae are situated , is opaque white or yellow
the cerata are variable in length and may be short and bulbous or elongate and cylindrical . they are arranged in 5 or 6 distinct groups , each elevated from the notum

in most aeolids the eggs and sperm producing structures ( gonads ) of the reproductive system consist of small spherical sac - like structures ( acinus , acini ) which sit in the body cavity above the viscera . usually there are separate male and female acini . if i look carefully at you photo i think i can see developing eggs in the acini in the left of your photo . each acinus has a fine duct connecting it to the rest of the reproductive system .

dear leanne & david , thanks for the photo . apart for the useful breeding record , the photo has good shots of the rhinophores . in this species the rhinophore club is papillate , but there are papillae only on the posterior side of the rhinophores , as your photo nicely shows . .
bill , is this a cuthona ? observed in a sheltered section at the eastern end of the narrow neck artificial reef . i have tried to be more observant as previously i had only seen one nudibranch on this reef and today i also counted 3 hypselodris obscura , so obviously it was lack of effort on previous dives .

dear leanne & david , this is an nice illustration of the life cycle of these animals which are so tied to their hydroid food . the branching object they are laying eggs on is the dead skeleton of a hydroid colony - perhaps the one they have been feeding on - and now that their food supply is gone , they can make one last move to continue the species , by laying the eggs which contain the next generation .

dear gary , this species is found throughout the tropical pacific and indian oceans , and i have found it as far south as sydney in new south wales . these animals are very dependent on their food , in this case a hydroid , so sometimes they can be found in quite large numbers in a particular spot . for that to occur , their food needs to be present , and their free - swimming larvae needs to be drifting past in the currents and be mature enough to settle down and become crawling slugs .
this colour form , in which the red lines are broken into short dashes , is quite common in eastern australia . best wishes , bill rudman
i believe this is an aeolid nudibranch , information from a coffee table book ( the living seas - marine life of the southern gulf , 1989 , dipper and woodward ) . i have searched some books ( e . g . debelius 2003 ) the sea slugs web pictures and found none that compare well to it . any suggestions ?
locality : clives crane wreck , east of al - khor , qatar , persian gulf , indian ocean . depth : 25 m . length : 25 - 40 mm . june 2004 . photographer : iain macdonald
image data : hidayet , kas , antalya , turkey . october 1999 , 10 - 12mt / 4 - 5cm , sea grass bed .

hi dr . rudman , here is another nudibranch i snapped recently at pulau dayang off the east coast of malaysia . kheong .
photo : adnan buyuk : ado2000tr @ urltoken - upper right , lower left ; and photo : hasan yokes : hyokes @ urltoken - lower right .
it has similarities to some mediterranean species , but none of them have three red stripes down the body and the papillate rhinophores .
for those of you interested in exotic introductions to the mediterranean , there is a website ciesm atlas of exotic species in the mediterranean sea which has a list of introduced molluscs , including quite a few opisthobranchs . there is a comprehensive page on each species , but unfortunately no photos .
the animal was collected at suakin , sudan , red sea , 18 april 1980 , by chris todd . am c131641 [ 13mm long preserved ] .
this species was originally described from the red sea ( suez , egypt ) and animals from that region tend to lack the pinkish background colour found in animals from the western pacific although other aspects of the colour and the radular morphology are the same .
i have added these photos so that they can be compared with the photos in baki yoke ' s recent message from turkey .
encountered this one at the pipeline , nelson bay , port stephens [ new south wales , australia ] in early march .
dear bill , you ' ve mentioned several times that you ' re interested in images of nudibranchs feeding . i think these two photos qualify . they were both taken on 2 april , 1999 , at fly point , port stephens , new south wales [ australia ] . the depth was 8m .
unfortunately it is when you try and get food items identified that you find that it is not only nudibranch taxonomists we are short of . so in most cases i photograph the food item and preserve it so that hopefully , some time in the future , i will find someone who is able to identify it . so any little bit of information , like erik ' s photos , is welcome best wishes , bill rudman
in november 1996 i found at sipadan island ( malaysia ) another specimen which looks , i think , similar to aeolidiella indica . it is a small slug of about 12 mm .
rudman , w . b . , 2000 ( jul 11 ) . comment on aeolid from malaysia by fredy brauchli .
dear bill , thank you for id of hallaxa hileenae and h . paulinae .
here is an eolid species i found at 5m depth on coral rubble [ at kerama is . near okinawa ] . this size is 13mm long .
bill , we found this at fly point , port stephens , new south wales over christmas . thanks , david & leanne atkinson .

the posterior face of each rhinophore bears over 120 densely packed , elongate papillae . the rhinophores are thick basally , and terminate in a distinctly apex
the oral tentacles are cylindrical throughout their length , tapering to an acute apex . basally , the oral tentacles are the same color as the rest of the body . their middle third is deep purple and the outer third is generally opaque cream yellow . however in some specimen from aldabra atoll ( gosliner , 1990 ) and other country ( rudman and nudipixel ) , there is no opaque pigment on the outer portion of the tentacles and their are the same colour as the rest of the body
the cerata are slightly elevated from the notum on a common peduncle . the basal half to two - thirds of the cerata is pinkish purple . above this section a deep purple ring is present . the apical portion of the cerata is opaque cream yellow . they are thick and cylindrical for most of their length , and they taper to an acute apex
the anterior foot corner are enlarged and tentacular , and usually recurved posteriorly when the animal is crawling . purple pigment is present on the apical portion of the foot corners .

this is small and flamboyantly colored species of aeolid , with variable degree of pink - red coloration , including lined and unlined individuals , on the body and cerata .
little is known about the relationship of this species to other members of the genus .
sexual , hermaphrodites . in most aeolids the eggs and sperm producing structures ( gonads ) of the reproductive system consist of small spherical sac - like structures ( acinus , acini ) which sit in the body cavity above the viscera . usually there are separate male and female acini . each acinus has a fine duct connecting it to the rest of the reproductive system .
this is a widespread indo - west pacific tropical and subtropical species . in australia , it is known from new south wales , northern territory , queensland , victoria and western australia ( australian fauna directory website , searched 2 / 06 / 2017 ) .
