Orcas hunt cooperatively, using strategies like carousel feeding to catch fish and stunning prey with tails or flippers.
Hunting Marine Mammals
Orcas also hunt seals, sea lions, and even dolphins, using intelligence, teamwork, and tactical approaches, including beaching themselves temporarily.
Unexpected Prey Choices
They occasionally hunt other dolphins, showcasing their adaptability and complex predatory behaviors in marine ecosystems.
Communication and Social Structure
Clicks, Whistles, and Songs
Orcas communicate through clicks, whistles, and songs. Each pod has a unique dialect, taught from mothers to calves, helping them identify each other.
Matriarchal Pods
Orcas live in family pods led by older females who prioritize the pod’s survival, share food, and ensure strong cooperation.
Social Bonds
