A new BBC documentary shows a pod of killer whales hunting a seal using a sophisticated technique. They used "wave crashing," creating a wave to break up an ice platform and trap the seal on it.
There are anecdotal reports that, c. 1955, an Inuk man fell prey to an orca entrapped by ice in Grand Suttie Bay (Foxe Basin, Canada).A pod of orcas (likely 10-12 animals) was trapped in a polynya, and a young man visited the site in spite of advice from elders to wait until the ice was strong enough.
Although resident orcas have never been observed to eat other marine mammals, they occasionally harass and kill porpoises and seals for no apparent reason. [106] Some dolphins recognize resident orcas as harmless and remain in the same area. [107] Orcas do consume seabirds but are more likely to kill and leave them uneaten.
At least 15,000 whales are estimated to inhabit the North Atlantic. [35] In the Northeast Atlantic, two orca ecotypes have been proposed. [36] Type 1 orcas consist of seven haplotypes and include herring-eating orcas of Norway and Iceland and mackerel-eating orcas of the North Sea, [36] as well as seal-eating orcas off Norway.

The skull of the leopard seal. The leopard seal has a distinctively long and muscular body shape when compared to other seals. The overall length of adults is 2.4–3.5 m (7.9–11.5 ft) and their weight is in the range 200 to 600 kilograms (440 to 1,320 lb), making them the same length as the northern walrus but usually less than half the weight.
