justification : japalura tricarinata has been assessed as least concern owing to its large distribution . no specific threats have been reported and this species is not undergoing significant population declines . further research into the taxonomy of the genus japalura , including j . tricarinata is needed . monitoring is required to ensure that the localized threat of deforestation does not become more widespread .

as the
younger sibling
to the chameleon , the armattan japalura is the fanciest micro frame around , and the second design in armattan ' s selection that features aluminum protection . inspired by many of the same principals as the chameleon , the japalura is a lighter , more compact package that still supports many of today ' s fpv standards . this
3 inch
frame can handle full - sized miniquad guts , houses your standard hs1177 camera , and shields everything but the battery with two 4mm thick 6061 aluminum ribs .
the specific epithet is a noun in genitive case formed from the personal name hidetoshi ota of the tropical biosphere research center , university of the ryukyus , japan . his comprehensive work and taxonomic revisions of japalura species have immensely contributed to our current knowledge of this genus .

according to teldap . tw , taiwan ' s japalura breuipes is an arboreal ( lives in trees ) lizard that can grow to be a foot long . interestingly , new research into the island ' s jungles has provided a glimpse of a new relative of our lovely local lizard . this recently discovered creature measures 138 mm diagonally , and incorporates metal with its largely carbon - based body . fortunately for many of the collectors who have expressed interest in the organism , this little one prefers to keep its feet firmly planted on terra firma . we call this new lizard the japalura .
the japalura has been constructed to armattan standards , and we believe the frame is tough enough to warrant a top - to - bottom warranty . ( hah , see what we did there ? ) this baby is covered from the aluminum roll bars down to the smallest of top - plates .

the japalura is the newest quadcopter to the armattan micro quad lineup . it ' s a 130mm mini racer constructed using top of the line hardware . the quality that went into this thing is as high as it gets . super smooth carbon plates , that were cut to perfection , even the edges are smooth . the frame is a work of art and comes in 2 colors : purple and silver . the fully built prototype that i received , contained the following hardware :
the armattan japalura is the little brother to the popular armattan chameleon . the components used here will work on either the 3
or the 4
baseplate . traditionally 1407 motors have been used exclusively on 3
builds , but a new trend has emerged putting 4
props on a 3
powertrain . the advantage is a light - weight build with the flexibility to choose either 3
or 4
props and carry an hd camera . this particular configuration can easily handle a mobius mini .
diagnosis : following inger’s ( 1960 ) definition of the genus , the new species is assigned to japalura based on a number of diagnostic characters , including : ( 1 ) dorsal scales unequal in size ; ( 2 ) enlarged crest scales present ; ( 3 ) gular pouch present ; ( 4 ) lateral fold of skin in axilla - groin region present ; ( 5 ) supraciliary scales greatly imbricate ; ( 6 ) head relatively long , flat ; ( 7 ) tail long , slender ; ( 8 ) tail cylindrical in shape ; and ( 9 ) precloacal and femoral pores absent .
diagnosis : following inger’s definition of the genus ( inger , 1960 ) , the new species is assigned to the genus japalura based on a number of diagnostic characters , including : ( 1 ) dorsal scales unequal in size ; ( 2 ) enlarged crest scales present ; ( 3 ) gular pouch present ; ( 4 ) lateral fold of skin in axilla - groin region present ; ( 5 ) supraciliary scales greatly imbricate ; ( 6 ) head relatively long , flat ; ( 7 ) tail long , slender ; ( 8 ) tail cylindrical in shape ; and ( 9 ) precloacal and femoral pores absent .
as with any armattan release , some of the best features of this frame are the lack of restrictions you have when building . for example : like usual , the japalura supports a 30 . 5mm center stack up to 28mm high . in addition , the adjustable angle on the aluminum vtx mount supports a variety of transmitter options . another feature is the option to mount the battery on the top or the bottom of this machine , just in case you have a strong preference . lastly , if built with an eye on the weight of all the components , you ought to be able to skate by underneath the united state ' s faa registration restriction of 250g .
the japalura is equipped with a foxeer hs1177 camera upgraded with a gopro lens . the vtx is a foxeer tm200 - 200mwvtx connected to this is a lumineer axii 5 . 8ghz antenna . this was the first time i ' ve even seen a mini antenna like this , i am happy to say that it performed great - it ' s small makeup makes it light , but it also performs just as good as any other antenna i ' ve used . as far as the rest of the fpv gear goes , everything worked as it should , excellent range , excellent picture quality , can ' t think of a single negative , so i will leave it at that .
i was amazed at how smooth and easy it was to fly this thing . i ' ve flown other smaller sized quads and none come close to how good this thing feels . i ' m not the best at tuning quads , actually i use basically the same tune on all of my quads , with slight variations . so with the japalura , even with a moderate tune , it feels locked in . i think a lot of it has to do with the fc and esc ' s - it ' s able to process noise and errors out resulting in a super smooth flight . and because of this : i feel so much more confident when i am out flying .
japalura iadina sp . nov . differs from j . laeviventris by having a smaller adult body size ( svl 54 - 65 mm v . s . 64 - 72 mm ) , distinctively keeled ventral scales of head and body ( v . s . smooth or weakly keeled ) , fewer md ( 35 - 46 v . s . 57 - 59 ) , distinct ground coloration of the dorsal surfaces of head and body in males ( emerald green v . s . off - white ) , distinct coloration of gular spots ( blue in males , greenish yellow in females v . s . orange in both sexes ) , and distinct patterns of pigmentations on the dorsal surfaces of the body along the dorsal midline ( black vertebral stripes speckled with green v . s . m - shaped patterns of dark brown pigmentation ) .
the frame is not just attractive , its also tough as nails ( i ' ve been in some pretty gnarly crashes ) - aside from a few scratches , the frame remains in excellent condition . its thick in all the right places , and yes , there are a crap load of screws , but this just adds to the frames strength . the final version of the japalura have slight changes to the bottom and side plates . from the pictures it looks like the arms were rounded out at the end , and the side plates were made taller and wider . the frame has holes to support mini flight controllers w / 20x20mm mounting holes , and also holes to fit regular sized fc ( 30x30mm mount holes ) . the front portion of the frame angles upwards and allows fitment of full sized cameras similar to an hs1177 . holes in the frame allow the camera to be mounted directly to the frame , and allows uptilt angles of nearly 90 degrees .
japalura laeviventris sp . nov . can be distinguished from all congeners by the combination of the following suite of morphological characteristics : ( 1 ) small adult body size ( svl 67 - 72 mm in males , 64 - 70 mm in females ) ; ( 2 ) moderate tal ( tal / svl 168 % - 200 % ) ; ( 3 ) moderate hll ( hll / svl 64 . 3 % - 78 . 4 % ) ; ( 4 ) nsl 1 ; ( 5 ) t4s 22 - 26 ; ( 6 ) sor 3 ; ( 7 ) strongly - protuberant , conical , post - tympanic scale absent ; ( 8 ) strongly - protuberant , conical , post - rictal scale absent ; ( 9 ) tympanum concealed ; ( 10 ) nuchal crests relatively raised on weak skin folds ; ( 11 ) dorsal crests weakly developed without distinct skin folds in males ; ( 12 ) transverse gular fold present ; ( 13 ) gular pouch distinct , present ; ( 14 ) scales of ventral surface of body smooth or weakly keeled ; ( 15 ) md 57 - 59 , ( 16 ) ground dorsal coloration off - white in males , brownish - gray in females ; ( 17 ) dorsal , lateral , and ventral surface of head , dorsal forelimbs , and lateral surface of body speckled with black ; ( 18 ) distinct radial streaks around eyes ; ( 19 ) dorsolateral stripes present , smooth - edged , pale - yellow in males ; ( 20 ) dark - brown , “m” - shaped pigmentation patterns along dorsal midline in males ; and ( 21 ) small , triangular , orange gular spots in adults of both sexes .
available in either silver or purple , this frame looks smashing when paired with oomph 1407 motors .

too cheap to be real ? how is this possible ? furibee x215 review .
here we ' re using the new kiss all - in - one flight controller . joined with the x4r receiver and tbs unify vtx we can tune pids and change radio frequencies through a taranis . while support for the tbs unify isn ' t cooked into the kiss firmware at the moment , it will be released any day now .
it ' s best to start by fitting the stack . sometimes this can be the most time consuming part of the build depending on your stack space and standoff selection . it ' s definitely good to have a wide variety of standoffs on hand because the included standoffs rarely ever work . here i used 7mm anti - vibration standoffs . while most flight controllers work just fine , soft mounted or not , these are less prone to break and could potentially improve flight performance . that being said , they can be troublesome to fit as the female end is more shallow than a typical standoff . i ended up sending a 5mm screw with a 1mm spacer through the bottom plate into the anti - vibration standoffs . without the spacer the threading is too long .
next you ' ll want to mount the motors . normally i attach them using two screws at first in the event that i need to remove them for whatever reason . just don ' t forget to finish them up with loctite before the maiden . once the motors are in place and the flight controller is mounted you ' ll want to cut the wires to length . i used 2
lengths paracord 550 to protect the wires , but that ' s entirely optional .
you ' ll want to cut each motor wire to length individually to reach their respective esc pads . while kiss doesn ' t support motor rotation changes via software , you can solder jumper pads to change the rotation as necessary . to cut each wire you need to lay it down flat against the arm , run it up to the standoff , follow the edge of the board and divert straight up into the groove of the esc pad . it ' s important that the wires remain under the flight control board otherwise they ' ll get in the way of the canopy mounts .
you ' ll also want to solder the xt30 connector to the lipo input pads of the flight controller . i like a short lead here , so 2 - 3cm should be sufficient .
since kiss doesn ' t allow you to test your motor rotation without a bound transmitter , you ' ll want to wire up your receiver first . this is fairly straightforward , so just refer to the photos to learn the wire positions . to prepare the fc pads , add a little flux and create a nice shiny pillow of solder . the key is to leave none of the copper pad showing . this is where a quality iron is important . if the solder makes a pointy bit as you pull away you either aren ' t operating at a high enough temperature ( 750 to 800 degrees ) or your iron tip lacks sufficient flux .
now you need to bind your rx and test the motor rotation . first download the latest kiss
cc
fc firmware and install kissfc to google chrome . to update the firmware open kissfc , plug the usb cable into your flight controller , hold the boot button and plug the other end into your computer . while continuing to hold the button choose the firmware you downloaded and flash it . if you let go too early the process will fail .
after the firmware has been updated , attach a lipo , connect to the board and click
data output
to test the motor rotation . i normally rub each motor to feel the rotation direction . for any motor that spins the incorrect direction solder the corresponding jp1 jumper for that motor . refer to the kiss compactctrl
cc
manual for details .
once you ' ve completed these steps you can mount your rx and antennas . what i did was use a couple layers of double sided tape to prevent any potential shorts against the flight controller . using wide shrink tube would be a better solution , but i had none wide enough for this rx . the antennas are incredibly long , so i rotated the u . fl connectors 180 degrees to send the antennas forward . i wrapped them around the standoffs across to the other side , and out behind the front arms . if you do it just right you ' ll manage 2in of zip tie for the tips of both antennas .
now you can assemble the canopy and wire the camera and vtx . be sure to mount the antenna holder flat side out so the wings of the pigtail catch the lip . this prevents the pigtail from rotating as you attach your antenna . since we ' ll eventually be using tbs smartaudio , you can solder the audio wire of the vtx to the tx pad of the fc . now depending on which version of the tbs unify you ' re using ( hv or 5v ) you ' ll either want to solder the power leads to the lipo input pads or the rx 5v / gnd pads . once you ' ve done this you can solder the runcam wires to the vtx wires to complete the wiring . just be sure to leave enough slack to remove the canopy .
now you can attach the canopy being careful not to pinch any motor wires . i found that the pigtail can assert just enough pressure to hold the vtx to the top of the rx , so i didn ' t use any tape to hold it down . it seems to fit just right behind the camera , so i don ' t believe it ' ll be moving around in there . be sure to loctite your motors and you should be ready to maiden !
i ' ve been itching to fly this one . i ' ll see if i can take a screenshot when i get in there .
i can get about 3 minutes on an 850mah 4s pack . i haven ' t tried anything larger .
battery on the bottom and i ' ve got a mobius mini mount that fits directly on top placing the camera at an angle over the fpv cam cage . it ' s a great fit !
first of all , impeccable build . . . as a retired rf engineer , i really appreciate excellent workmanship and you ' ve done it here . do you have any photos of the mobius mini mounted to this frame ? i would love to see the mounting system . congrats . . . a beautiful piece of work .
thank you ! i haven ' t mounted the mobius mini on this one , but i do fly it with a foxeer legend 3 . here ' s a photo :
looks pretty good , looks like a good option for sub 5
builds . thanks for the reply . . . cheers , dave
it ' s a great little cam . i ' d say the image quality is more or less on par with the session 5 .
that ' s impressive . . . thanks again for your input , it really helps a lot . happy landings . . .
hi ! i can ' t stop watching this beauty , thanks for posting it ! i love it and i ' ll build it with the exact same setup but 3
. i was wondering how much does it weigh ? ( i really want to be sub - 250g ) thanks in advance for your answer , and congrats . . . nicely done !
thank you ! i think you ' ll have a hard time keeping it under 250g with most 4s packs . maybe a light 3s pack would do it . this one is 182g without a battery .
sure thing ! why not build the 4
version ? you ' d have the option to use both 3
and 4
props at only the cost of a few extra g of frame weight .
glad you liked the jap 4 . i had a lot of fun designing that one . i thought the 5
would be my favorite , but the 4
definitely takes the win for me . i built 2 and i don ' t really fly anything else now .
great work ! when i first saw that there was a 4
version i just had to build it . i liked the 3
, but that size wasn ' t compelling enough to me . did you also design the chameleon ?
same here . i built the 3 , but i ' ve only logged like 5 min on it . not for me . i did design the chameleon as well . that was more of a group effort tho . chris ' s concept , my interpretation , and a lot of really great input . this was kind of my baby . i designed it as an aluminum hybrid version of my old kaeru frame . it was intended to be 5
as well , but then i saw what catalyst was doing with the 3 . 5
prop on 1407 motors and wanted to give 4
a try . they ended up beating me to the punch with their superlite . kinda nice that they did all the research tho . then chris said he wanted a 3
as well , so i scaled it back . surprisingly , i ' m the only one on the team to ever build the 4
.
well congrats on the successful designs ! the chameleon really has taken the scene by storm . i don ' t think a day or two goes by without a new chameleon post here . whose idea was it to go with the reptile theme ?
i like it . it taught me the name of a new reptile . always good to keep learning !
those are dal bi - blade 4045s . i thought i ' d go easy on this board , but apparently it can handle a bit more . i plan to try some tri - blades at some point .
thank you ! i ' m still trying to improve them , so hopefully they ' ll get better with time .
work of art ! o - rings work great to cover that extra distance the anti - vibration standoffs leave as well as a 1mm spacer .
thank you ! i wish i had done a nicer job on the esc solders , but it works .
that ' s shrink tubing . it ' s a must when you get into building quads .
before giving this a thorough review i thought i ' d do a teardown to see what makes the taranis x - lite tick . without getting into too much detail the x - lite is a new fpv transmitter designed to be compact and ergonomic . it ' s shaped like a video game controller but has all of the functionality of a traditional transmitter like the taranis q x7 or the taranis x9d . it features opentx and supports most . .
the bannilite was a collaborative effort between luke bannister , aka banniuk and falcon multirotors . the bannilite features ample camera protection , easy arm replacements and weighs in at only 72g . it even includes a spare arm and camera mount . it ' s an excellent choice for fpv racing and doesn ' t break the bank . the goal of this build was to feature a number of modern fpv luxuries including easy . .

to their 3 line : a 130mm prototype that was nearing it ' s final stages of production . talk about excited , i was on cloud 9 ! all
the final version has a couple slight changes to the main plate and side plates .
chris hooked it up with some rotorx props and stickers . these props are amazing ! excellent top end power .
the frame is made up of a number of carbon plates ( 5 ) and aluminum pieces ( 5 ) that are held together by lots of hex head screws . the bottom plate = 3mm and side plates = 1 . 5mm
vtx mount is adjustable , simply loosen the two 1 . 5mm hex head screws on both sides : lets you keep your antenna straight . i don ' t like bending my antennae
super smooth armattan 20amp blheli - s esc ' s upgrade - able through blheli suite .
lumineer axii 5 . 8ghz rhcp antenna - excellent , lightweight antenna , just a good as any other antenna i have used , but in a smaller form factor . weighing in @ 7 . 7 grams , and 2 . 8 inches long , with the thickest part being just 0 . 7 inches .
perfect fitment for the hs1177 and other comparably sized cameras ' . easily adjust though 2 screws placed on either side of the frame . i also like the fact that i can adjust the camera to have as much up - tilt as i need .
lastly the prototype i received uses a piko blx micro f3 flight controller . i believe the version that will be released will give you the option of other fc ' s .
with this board and the esc ' s , i was able to use 8k / 4k gyro & pid loop frequencies with cpu load @ 21 % . 8k / 8k brings cpu load to 41 %
brother hobbyt1 tornado 1407  3600kv  pure awesomeness ! the motors are the heart of this quad , and they impressed the crap out of me . these 1407 t1s are tiny but very powerful . they use high quality japanese nmb bearings , along with n52h arc magnets . i took a look inside the motor , and noticed a strange magnet arrangement . it would be two magnets placed close to each other periodically around the bell . i think this may be the reason for why the motor felt notchy . these motors have a ton of power , i ' ve been running them with 4s ( 450mah , 850mah , and 1000mah ) 3
props ( mostly 40 ' s and 45 ' s ) - i don ' t remember them ever getting hot , they seem to dissipate heat very well .
the included escs are armattans own 20amp blhelli - s , and the fc is a piko blx micro f3 from furious fpv . im not sure what is different with this flight controller compared to my other f3s , but it is able to achieve an 8k / 8k gyro update / pid loop frequency , and still stay under 45 % cpu load . i have mine set to 8k / 4k to be safe ( cpu load = ~ 21 % ) but i have flown it at 8k / 8k and didnt run into any issues . its pretty amazing how everything is not only getting better , but smaller too . the piko blx is a 27x27mm fc and uses 20mmx20mm mount holes . the armattan esc ' s are smooth as butter , not a single issue , i ' ve actually tried to make them desync , but nothing : it works flawless .
i didn ' t even think to mount batteries on top , thanks wickedwingman .
that ' s looking really nice . that was the
new thing
that chris promised to send you , right ?
very nice frame indeed . what other fc options ? also what aios could be used ? ( height )
sweet as ! ! ! m8 , ive just built a couple of 130 ' s and 150 ; s for us to throw around , maybe next time i will grab one of these frames .
it can fit the small 20mm or 30 . 5mm standard fc and pdbs . stack height from man plate to alumi roo bars is 28mm , and to the cf top plate is 30mm . to the cf cutout on the side cf plates is 21mm . see picture below . this is final rev using armattan mini 1407 oomph motors . this has a full size armattan mini pdb v3 with 5v and 12v regs on board , a full size xracer f3 controller , a dys 25 / 200mw vtx with a pigtail attached , and a full size x4r frsky rx with telemetry hooked up . we also have a full size hs1177 cam with a 2 . 5mm lens installed . it all fits very nicely . osd is optional , we can install them and they fit well . we use the piggy back osd that is designed to attach to the rear of the camera .
bare frame weights 51 grams fully assembled . so basically , this will fly super well on 1306 motors with very good flight times , then it will feel closer to what a 5 inch setup feels like with more modern 1407 motors on 4s . it ' s insane fast . some footage to come soon .
dan , thanks for review in so much details . much appreciate your professionalism throughout . best , chris
fantastic review ! glad you like it ! final revisions affect the main plate arm widths and side plates . production side plates leave room for straps for top mounted batteries or accessories and also have more clearance for fill size stack components . 2 board stacks are easily possible .
that quad is flat out far out . i like the looks of it better than my gt2 150 . no doubt from what i ' ve read about armattan on here she ' ll fly amazingly . hurry up and take my money , damn this hobby chooses to be expensive . thank you danq for the in depth review and youtube videos , subbed !

this species is found in northern india and eastern nepal . it occurs in the annapurna region of nepal , and eastwards into sikkim and west bengal ( schleich and kästle 2002 ) . macey et al . ( 2000 ) also recorded this species in xizang , tibet . schleich and kästle ( 2002 ) note that specimens collected in southern tibet have previously been misidentified as calotes jerdoni . this species is found between 900 and 2 , 900 m above sea level .
this species is locally abundant in zhangmu ( j . macey pers . comm . ) . schleich and kästle ( 2002 ) report that in ghorepani relatively high densities of this species were found .
this species is a terrestrial , rock - dwelling agamid ( sharma 2002 ) . in nepal , it is known from wet monsoon and rhododendron forests , and is most frequently encountered along forest edges ( schleich and kästle 2002 ) .
it is unlikely that any major threat is impacting this species , however , this species may be locally threatened as a result of deforestation . schleich and kästle ( 2002 ) note that the sporadic distribution of this species may be caused by the lack of remaining moist broadleaf forests .

hector 's dolphin ( cephalorhynchus hectori ) is the best-known of the four dolphins in the genus cephalorhynchus and is the only endemic cetacean to new zealand .

at approximately 1.4 m in length , it is one of the smallest cetaceans .

two subspecies occur : c. h. hectori , the more numerous subspecies , is found around the south island , and the critically endangered maui 's dolphin ( c. h. maui ) is found off the northwest coast of the north island .

maui 's dolphin is one of the eight most endangered groups of cetaceans .

the hector 's dolphin is also the world 's smallest and rarest dolphin .

a 2010/2011 survey of maui 's dolphin by the new zealand department of conservation estimated only 55 adults remain .

hector ’s dolphin was named after sir james hector ( 1834 – 1907 ) , who was the curator of the colonial museum in wellington ( now the museum of new zealand te papa tongarewa ) .

he examined the first specimen found of the dolphin .

the species was scientifically described by belgian zoologist pierre-joseph van beneden in 1881 .

māori names for hector 's and maui 's dolphin include tutumairekurai , tupoupou and popoto .

hector ' s dolphin is new zealand ' s smallest dolphin . these native dolphins are endangered in new zealand . find out how to behave when sharing the water with hector ' s .
location : hector’s dolphin is found only in the shallow waters around new zealand’s south island . a subspecies of hector’s dolphin , maui’s dolphin , is even more endangered with only about 110 individuals left . this member of the family lives around north island .
the north island subpopulation of hector’s dolphin was recognized recently as a subspecies , cephalorhynchus hectori maui ( baker et al . 2002 ) , and it has been assessed separately . this subspecies is sometimes referred to as maui’s dolphin ( not maui’s hector’s dolphin ) .

wwf works to end gill net use and trawling in hector’s and maui’s dolphin habitat . after the 2012 international whaling commission meeting , new zealand agreed to ban gillnets in a portion of maui’s dolphin habitat . this is a positive step , but a ban throughout the dolphin’s entire range is needed to ensure their survival . wwf is urging new zealand prime minister john key to protect the last remaining maui’s dolphins by prohibiting dangerous fishing gear from their habitat , safeguarding the region from sand mining and the threat of oil and gas exploration , and establishing a protected ocean corridor .
the results of the survey will be one consideration in the ongoing risk assessment for the species , and will factor into the hector ' s and maui ' s dolphin threat management plan which is due for full review in 2018 ,

according to the iucn red list of threatened species , north island hector ' s dolphins are
critically endangered
and south island hector ' s dolphins are
endangered
. hector’s dolphins are regularly caught in gillnets , which is by far the greatest threat to their survival . small population size , segregated genetic groups , and low population growth rates ( maximum plausible annual growth rate = 1 . 8 % ) pose a significant threat to their persistence . trawl nets , pollution , tourism , boat strikes and possibly mining are also thought to affect hector ' s dolphins .

set net fishing poses a major threat to hector’s and māui dolphin . like all marine mammals they need to come to the surface regularly to breathe . if they become tangled in set nets , they will hold their breath until they suffocate .
hector ' s dolphins of all ages spend a lot of time playing . they surf a lot at beaches when seas are quite rough . in calmer weather a favourite game is playing with bits of seaweed . the dolphin will carry it until it falls off or until some other dolphin
steals it
. they have even been seen playing with bits of floating sticks and leaves . hector ' s are very curious and people friendly which is why they like to visit boats .
hector’s dolphin is one of the smallest cetaceans , and new zealand’s only endemic cetacean . this charming little dolphin is only 1 . 4 meters long at the most , with the males being slightly smaller than the females . at its heaviest , this dolphin does not weigh more than 50 kilograms . hector’s dolphins do not have the beak usually associated with dolphins in general , but have instead a shorter face which makes them look more ‘whale - like’ . the back of this dolphin is light grey or white , with white extending down the front of the face . the throat and undersides are white , while black patches surround the eye region and extend to the rounded flippers . the round dorsal fin and the tail are also black .
clement said policy makers had been provided with with robust scientific evidence so they could make effective decisions around protecting and managing hector ' s dolphins .
new information from new zealand’s department of conservation reveals that a record six hector’s dolphins were found dead last december . five of the deaths occurred along the east coast of the country’s south island . the sustainable limit for this area is just one dolphin per year . another individual was washed up along the west coast . in 1988 new zealand’s established its first marine mammals sanctuary to protect the hector’s dolphins against harmful fishing practices , the primary cause of their decline . but sanctuary is failing in its task because it is simply too small . read more . . .

hector ' s dolphin is endemic to the coastal waters of new zealand , where it is threatened by fisheries bycatch , pollutants and boat disturbance . recent surveys estimate the total abundance at about 7000 animals , fragmented into three populations around the south island , and a sub - species ( māui dolphin ) on the west coast of the north island .
the average lifespan of hector ' s dolphins has not been documented . however , the oldest recorded individual was 20 years old at time of capture .
banning the use of set netting . south australia , and several states in the us have already done so , and this is the only way to ensure no more hector’s or maui’s die in this way .
this species was once hunted for bait , but this has now stopped . due to the coastal habitat of hector ' s dolphin , the species is vulnerable to a large number of different threats such as chemical pollution , vessel traffic and habitat modification .

the new zealand government has exposed its anti - conservation stance in the most spectacular way . at the recent iucn world conservation congress , new zealand was the only nation to cast a vote against a motion in favour of better protection of the last 55 or so maui ' s dolphins and their endangered cousins , the hector ' s dolphin . with about 6000 daily participants , the meeting is the world’s largest conservation event and brings together professionals and governments to discuss the environment . the iucn ' s demands perfectly match those of our

calista w . has opened her heart to the plight of new zealand maui’s dolphins in a big way . just eight years old and about the size of a maui ' s dolphin , she is on a mission to tell the dolphins ' sad story and to touch your heart .
the reproduction rate of hector’s dolphin is extremely low : barely 2 percent per year . they breed 2 - 4 times a year , and females can only have up to 7 offspring throughout its life . males reach sexual maturity at 5 - 9 years and females at 7 - 9 years of age . both are polygamous .

this dolphin tends to occur in small groups of two to ten individuals . these groups sometimes join together forming larger temporary aggregations . hector’s dolphins undertake short dives for about 90 seconds and feed on a variety of small fish and squid . hector’s dolphins reproduce slowly and without human impacts have a maximum population growth rate of about 2 percent per year . females reach maturity at around 7 to 9 years of age , and males between 5 and 9 years . courtship behaviour involves close contact , leaping , chasing and belly displays . each female has one calf every 2 - 4 years which tends to be born between late spring and summer ( 6 ) . a maximum age of about 20 - 25 years has been observed . hector’s dolphins are unusual in that they only produce short , high frequency clicks , not whistles like many other species of dolphin ( 7 ) .
the findings of a three - year marine aerial survey to update the dolphin ' s population and distribution show there are between 12 , 000 and 18 , 500 dolphins , almost double the last estimation of 7000 .

in 2008 , jim anderton ( then minister of fisheries ) put in place a comprehensive package of protection measures for maui’s and hector’s dolphins . again , the trust was at the forefront of this development , providing most of the research data and public education essential to reaching this goal .

aggression in hector’s dolphins is expressed via tail - splashing , chasing , biting , and bubble - blowing . breaching , which is often done when feeding , appears to be associated with a state of excitement . in addition , lobtailing is associated with excitement and sometimes aggression . dolphins often flex their body at the water surface and swim on their sides during feeding . hector’s dolphins are slow swimmers relative to other delphinids and use an undulating motion to move through the water . dives usually last less than 3 minutes . hector’s dolphins tend to swim closer together when in close proximity to boats , which may be an indication of stress .

“the most contentious issue in this plan is how far to extend the set net ban . we are taking a cautious approach by banning set netting where there is clear evidence the maui’s dolphin go while not unnecessarily banning fishing where they are not . there have been five reported maui’s sightings in recent years in the area of the extension . there have been no sightings of maui’s dolphin south of the set net ban area despite 91 days of fishing trips monitored by independent observers on vessels over the past year , ” dr smith says .
commercial fishing nets used to be a problem but that too is improving . the department of conservation created the banks peninsula marine mammal sanctuary in 1988 to help offer refuge to those hector’s dolphins that had gotten injured .
the hector’s dolphin only inhabits around the south island of new zealand and a small region of the north island . its distribution is the most limited of all extant cetaceans . for habitat , it prefers shallow coastal waters with depths less than 100 meters . it lives about 7 kilometers off the coasts and can reach estuaries , river mouths , and shallow bays .

firstly come for an akaroa harbour cruise with us to really appreciate how special the dolphins are . we ' ll tell you all about them too , but there is nothing like seeing them for yourself to get a full appreciation . part of your ticket price goes towards dolphin research and education . other things you can do to help the dolphins is support the department of conservation as they find new ways to protect the species , including more marine mammal sanctuaries , which will stop dolphins being killed in set nets . doc also opposes marine mussel farms which may impact the dolphin’s habitat . if you own your own boat , and see the hector ' s dolphin , ask the driver to slow down to avoid turning suddenly . do not chase the dolphins . often , if you simply stop the boat , they will come and see you . avoid using set nets ( also called gillnets ) close to shore , where the dolphins are most common . if you ever see a hector ' s dolphin stranded on the beach , call the department of conservation , they would like to hear about it .
male hector’s dolphins reach sexual maturity between ages 6 and 9 , and females reach sexual maturity between ages 7 and 9 . they mate in the summer , have a gestation period between 10 and 12 months , and parturition occurs from early november to mid february . hector’s dolphins reproduce every 2 to 4 years and usually one calf is born at a time . females can give birth to a maximum of 7 calves during their lifetime .
feel free to remove post if of topic . my name is jurgen schwanecke . i ' m a year 12 student at rathkeale college in the wairarapa . me and a group of friends are part of a business group known as maui dolphin t - shirts . we are selling t - shirts that have critically endangered maui dolphin on them . we plan to donate 50 % of our profits to the nzwhale & dolphin trust . we would immensely appreciate the support for our cause to help protect the maui dolphin . you can learn more at maui tee project face book page thank you
