Orca whales

The orca is the largest member of the dolphin family and is not considered dangerous to humans. Its killer whale nickname is attributed to its voracious appetite for fish, sea turtles, aquatic mammals (including larger whales), and sea birds. Orcas live in more parts of the world than any other aquatic mammal, but they are more commonly found in colder waters. Orcas congregate in pods, with each pod having its own dialect. Orcas also have a highly defined social structure based on the female as dominant, and they demonstrate a great deal of care for their young. Animated, playful, and curious, orcas rely largely on sounds, including clicking noises, screams, whistles, and pulsed calls to communicate and locate prey.
