The orca, also known as the killer whale, is a large marine mammal belonging to the dolphin family. They are easily recognized by their distinctive black and white coloring, with a white patch above and behind the eye. Orcas are highly social animals, often living in groups called pods, which can consist of family members and other related individuals. Orcas are found in oceans worldwide, from the Arctic and Antarctic regions to tropical seas. They are known for their intelligence and complex behaviors, including hunting techniques that vary by region. Their diet primarily consists of fish, squid, and marine mammals, making them apex predators in their ecosystems.
