Killer whales hunt in pods, similar to a wolf pack, which is how they earned the moniker "wolves of the sea." A pod is a family group of up to 40 individual orcas and they prey on a variety on animals, using different techniques to capture them. While resident pods will focus on fish, transient pods are typically on the hunt for larger marine mammals.

Orcas work cooperatively to herd fish into a compact area where they're easier to consume. If they're after penguins, sea lions, or other animals on the surface, the killer whales will slap their tails on the water, creating a large wave that sends their prey off ice floes and within reach. Pods of orcas can take down something as large as a blue whale by surrounding it, then chasing and biting at the mammal until it weakens enough to be ripped apart and eaten.

As social creatures, orcas value sharing their hunt and females will share all the fish they catch with their offspring. Males, however, will only give away about 15% of their catch, typically shared with their mothers.
