A rare , unusually - colored bottlenose dolphinfish has catch the eye of Australian researcher . Its unequaled skin pattern has been attributed to piebaldism , earning the nautical mammal the nickname “ Speckles ” . investigator say that Speckles is the first piebald dolphin ever see in Australian waters .
Speckles was make out near a research vas in Hervey Bay , Queensland , on the afternoon of September 25 , 2022 . “ It was swimming with a grouping of five otherdolphinsabout 16 [ kilometers ] [ 9.9 miles ] off Hervey Bay ’s Scarness Beach and we noticed it straight away as it had such unknown coloration compare to the others , ” said doctoral student Georgina Hume of the University of the Sunshine Coast , lead writer of a paper documenting Speckles , in astatement . The group was seen to be foraging during the 40 - minute period they were respect .
The researchers were n’t actually seek out funky - patterned cetaceans – they were there to take how dolphins in the domain are colligate when they encounter to come across this strange creature .

“ Speckles leapt out of the urine three time in an upright , erect position , while the eternal rest of the group travelled in a ‘ porpoising ’ motion , ” Hume carry on . Porpoisingis affiliate with fast swim , wherecetaceansleap out of the water while race along . “ This allow us to get a very vindicated look at its underside which had many blanched area , along with white stripes across its dorsal and sidelong sides . ”
“ Piebaldismis alike toalbinismandleucism , where the animals typically have white skin , feathers or pelt , whereas piebaldism is a fond - red of pigmentation so the individuals show this patchy coloration , ” explain study co - supervisory program , behavioral ecologist Dr Alexis Levengood .
Piebaldism occursdue toa lack of cells that produce the pigment melanin in certain areas of the pelt . The researcher take down that it ’s uncommon to find atypical color like this in marine mammalian – only 24 someone have been documented in lit , and just six have been caught on camera . It can number with a whole host of downside , such as being more easily spotted by both predators and prey , as well as the lack of melanin potentially increasing susceptibility to sun damage and decreasing heat absorption when the water experience parky .
Luckily , Speckles was observed to be a healthy sizing – the fact it surface multiple multiplication tightlipped to the research vessel allow researcher to estimate its duration to be around 3 meter ( 9.8 foundation ) – with a heal shark bite on the right side of its peduncle . Speckles ' sex could not be determined . “ The clear designation of close - proportionate livid patches and the overall ‘ healthy ’ appearance of Speckles help eliminate the possibility that these patches are due to potential disease or stranding - touch on suntan , ” explained Hume .
“ It ’s an exciting discovery , as to day of the month , there are no documented sighting of any untypically coloured dolphins in Australian water , ” Levengood articulate . “ There have however been a few sightings of atypicalwhales . One of these is a well - have it off albino kyphosis whale called ‘ Migaloo , ’ first observed in Byron Bay in the early nineties and whose all - white status was confirmed from a sighting in Hervey Bay one year by and by . "
Unfortunately , Speckles was not sighted by researchers again in 2022 after that fortune encounter , despite them assay to find it again the next day . Levengood advocate “ transmitted sampling of both common bottlenose dolphin and Indo - Pacific bottlenose dolphins in and surrounding Hervey Bay , to measure the population genetics and relatedness of individual that might be influencing atypicalcetaceanskin pigmentation . ”
The study is published in the journalAquatic Mammals .
