How do orcas hunt cooperatively in the ocean?

Orcas, or killer whales, are highly social predators that often hunt as a coordinated pod. In some regions, they herd fish into tight balls; in others, they create waves to wash seals off ice floes or work together to isolate prey. These tactics can vary by population and are often learned from older animals rather than invented individually. Orcas are found in many oceans and are known for complex vocal communication and strong family bonds. Their teamwork makes them one of the most effective hunters in the marine world.
