Orca, also known as the killer whale, is a highly intelligent marine mammal belonging to the dolphin family, Delphinidae. Distinguished by its striking black and white coloring, the orca can be found in oceans all over the world, from frigid polar regions to more temperate tropical waters. Known for their complex social structures, orcas live in pods that exhibit sophisticated hunting techniques and vocal communication methods. They are apex predators, with a diet that includes fish, seals, and even whales, varying by population and region. Despite their formidable name, orcas have generally benign interactions with humans in the wild.
