The largest dolphin family member is the ORCA, also known as the Killer Whale. It is the largest species of the oceanic dolphin family and is easily recognizable by its black and white coloration. Orcas are highly social and live in groups called pods. They are found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas. They are apex predators, meaning they have no natural predators. Orcas are known for their intelligence, playfulness, and striking appearance.
