The orca is actually the largest dolphin in the world. It is one of the most intelligent marine mammals and hunts in coordinated groups.

The body is black with striking white spots. The dorsal fin of the males can grow over 1.5 meters tall. The animals have powerful teeth and a very muscular body.
No natural enemies
Not poisonous. Rarely dangerous to humans in the wild.
Orcas have complex family structures. Each group has its own hunting techniques and even its own “dialects” in their sounds.
