The orca is the largest dolphin and the apex predator of the oceans. This social marine mammal has black-and-white coloration and high intelligence.
The orca differs from other dolphins in its larger size, high dorsal fin in males, and complex social life in families. It is important for nature as the main predator that regulates the population of other marine animals.
