Noaa scientists find killer whales in antarctic waters prefer weddell seals over other prey Noaa scientists find killer whales in antarctic waters prefer weddell seals over other prey Noaa's fisheries service scientists staring at the cooperative hunting behavior of killer whales in antarctic waters observed the animals favoring one type of seal over all other available food sources, in a study published in the journal marine mammal science.Analysis robert pitman and john durban from noaa's southwest fisheries science center in la jolla, calif, watched killer whales hunting in ice floes, off the traditional american antarctic peninsula during january of 2009.While documenting the whales' behavior of on purpose creating waves to wash seals off ice floes, they noticed weddell seals as their primary target, despite the of other prey species, specially the more abundant crabeater seals. "These killer whales would identify and then attack weddell seals almost entirely, even though they made up only about 15 percent of the disposable seal population, wanted to say pitman. Killer whales creating waves to wash seals off ice floes in antarctica had previously been observed only a number of times.The entire Pandora Bracelets UK whales, sometimes up to seven abreast, charge the ice floe creating a wave that either washes the seal off the ice or breaks the ice into smaller pieces and weaker to another attack. If your seal was washed off the ice, the killer whales worked as a group to keep it away from hauling onto the protection of another ice floe.The whales seemed to try and confuse the seal by causing turbulence within water with their flukes and blowing bubbles under the water through their blowholes. From the ice, the whales attempt to tire and finally drown the animal by pulling it under water by its hind flippers.Eventually the seal succumbs to exhaustion and is usually divided up among the pod members marine.Most of the time, little of the seal's remains float to the counter, but in one instance the carcass rose to the surface and appeared to have been systematically skinned and dismembered before being eaten.
