Killer whales are beautiful and olympian , but there ’s very little variation in what they await like — their shape , size and coloring are pretty standard from whale to whale . So , when people jump spottingkiller whaleswith a noticeably different physique — flimsy , with much smaller white center patches and narrower , sharp dorsal 5 — scientists paid attention .
In January , an outside team of researchers tracked down these potential killer whale role player and collected samples for genetic examination that will discover whether or not the creature are a newfound , distinct coinage of killer whale .
Type D whales could be a new species of killer whale.
" We are very excited about the transmissible psychoanalysis to number , " Bob Pitman , a investigator from NOAA Fisheries ' Southwest Fisheries Science Center in La Jolla , California , said in astatement . " Type D cause of death hulk could be the big undescribed animal left on the planet and a absolved indication of how little we know about life in our sea .

Not a fish story, after all
Until now , the beingness of this potentially newfound mintage was based only on stories from black cat and a smattering of photographs .
The first record of these mysterious whales date back to 1955 when 17 of the animalsstranded on the glide of New Zealand . While their markings resembled known killer whales , these animals were small , with a blunt schnozzle and bulblike head . The marooned whales also had narrower , pointy dorsal fin and much small livid patches above their eyes compare with typical killer whale . Experts meditate that the unusual whales were simply a product of a genic optical aberration that exist in only those individuals .
Then , in 2005 , a French scientist showed Pitman pic of some odd - looking killer giant that were steal fish from fishers in the Crozet Islands in thesouthern Indian Ocean . The whales search just like the one that had ground in New Zealand , more than 5,500 miles ( 9,000 kilometers ) away . This suggested that the unique whales were more widespread than antecedently cerebrate .
At top is a drawing of a typical adult male killer whale. Note the size of the white eye patch, less rounded head and dorsal fin shape. On the bottom is a drawing of an adult male Type D killer whale. Note the tiny eye patch, more rounded head and more narrow, pointed dorsal fin.
For the next few old age , Pitman and his colleague pile up 1000 of images from holidaymaker and vessels operating in the Southern Ocean . By 2010 , Pitman and his squad had collected six images of the wanna - be killer whale , which they dubbed the " Type D " killer whale .
The photograph of the Type D whales were snapped at latitudes that often live theworst boat stipulation on the planet — area known as the Roaring forty and Furious L because of the punic winds in the region . If the Type D whales liked to hang out in those spotlight , then it was no wonder humans had n’t laid eyes on the whale until recently .
The final piece of the puzzle
After years of gather information about a potentially undescribed specie of killer whale , Pitman pretend out to sea to feel the secret beast . He recruited an outside team of maritime mammal experts to come with him . In January 2019 , the team left the shore of Argentina and found a fuel pod of about 30 Type D whales .
The squad pass about 3 hours with the chemical group of whale , all the while commemorate the sights and sounds of the showdown above and below the H2O . The researchers also roll up three biopsy , or tiny bit of pelt , from the whales , which will undergogenetic testingto reveal how closely related the Type D whales are to typical killer whales .
accord to Pitman and his team , the find of the Type D killer whale serves as a admonisher of how much we have depart to larn about life in our sea .
