Orca

The orca, also called the killer whale, is a large member of the dolphin family with bold black-and-white coloring. It is a toothed marine mammal that hunts using sound and coordinated movement. Diet and social customs differ strongly among populations. Some groups specialize in fish, while others hunt marine mammals or other prey. Family relationships and learned behavior shape how individuals communicate and feed. A tall dorsal fin and pale eye patches make orcas recognizable at the surface.
