Scientists say they’ve determined a mysterious type of killer whale they have been trying to find for years. It lives in components of the sea near Antarctica — and it may be the most important animal to have remained unidentified with the aid of biologists. The belief that there is probably some unusual type of killer whale emerged in 1955. Photos from New Zealand confirmed a gaggle of whales stranded on a beach.
This becomes a totally exclusive-searching institution of killer whales,” says Robert Pitman, a marine ecologist with the National Oceanic and Atmospheric Administration. The whales were smaller than other killer whales, with rounded heads and pointier fins. “And most importantly,” Pitman adds, “they’d like a little tiny eye patch,” a white spot underneath every eye function of killer whales. These patches have been tiny and nearly nonexistent in a few cases. Biologists were mystified. Then, in 2005, Pitman met a French biologist at a technological
know-how conference who confirmed him a photograph of an unusual-searching killer whale swimming within the southern Indian Ocean. “And I regarded down, and there they were, the New Zealand killer whales,” he remembers. For Pitman, the search becomes on. Last year, he assembled a team to visit Cape Horn in Chile to search for what’s now technically called the “type D” killer whale. Local anglers complained that some form of whale changed into stripping fish of their traces. NOAA biologist Lisa Ballance, who’s married to Pitman, become
a part of the crew. “From the beginning, I had cited it because of the needle in the haystack,” she says. “It’s a big ocean, and it is a hard ocean.” It changed into a slow start. Their ship at Cape Horn became trapped at anchor for 8 days via howling climate. But then they got a 12-hour quiet spell. “We left that night,” Ballance remembers, and “pounded into the seas so that we should get to our spot at first mild the next morning.” Pitman explains the tale: “The solar got here up in the morning at five:50. We had kind D killer whales swimming around our boat.” “There they have been,” Ballance remembers, confused for a second. “Uh … I can not even … It changed into thrilling for everyone.” Pitman provides: “It’s like seeing a dinosaur or something. It’s one of these moments that biologists stay for. And I stated, ‘That’s it! That’s the New Zealand killer whale!’ ” There changed into no mistaking
its extraordinary look, says Ballance. “Visibly,” she says, “this shape is the most uncommon and awesome shape of a killer whale on the planet.” Later, they found out why the whales swam as much as them. The group had diminished an underwater microphone over the side on an extended cable, with cameras attached. Pitman says it needs to have appeared like a fishing line with fish on it — it gave the impression of breakfast. “And you may imagine them wondering, ‘Hey, wherein’s our fish?’ ” he says.
But that was, undoubtedly, the way to carry them to the boat.” The team became capable of sniping off small tissue samples from the whales by firing an innocent dart attached to a line into their skin. An evaluation of the DNA will determine if that is a very new species or just an unusual subtype. Either manner, the thriller killer whales of the Southern Ocean have been observed.
