An orca is a large, powerful ocean mammal, also called a killer whale, though it's actually the largest member of the dolphin family. Orcas are easy to recognize: they're sleek and black with distinctive white patches near their eyes and on their bellies. A full-grown orca can reach 30 feet long and weigh up to six tons, about as heavy as an elephant.

Orcas are apex predators, meaning they're at the top of the ocean food chain. They hunt in family groups called pods, working together with remarkable intelligence to catch fish, seals, and sometimes even other whales. Different orca pods develop their own hunting techniques and communicate with unique sounds, almost like different cultures or dialects. Some pods specialize in hunting salmon, while others might focus on seals or rays.

These animals are extraordinarily smart. They can solve problems, teach their young complex skills, and coordinate elaborate hunting strategies. Scientists have observed orcas creating waves to knock seals off ice floes, and using clever tactics to confuse schools of fish. They live in tight family groups led by experienced females, and family bonds can last their entire lives.

Despite the name “killer whale,” orcas aren't a threat to humans in the wild.
