The orca, or killer whale, is a large, marine mammal found in oceans around the world. Its black and white pattern and dorsal fin are distinctive features easily recognizable to most people. Research tells us orcas inhabit all of the world's ocean basins, in both coastal and pelagic environments.

Known for its intelligence, orcas live in social groups and adults have complex roles in the family. Orcas are considered the largest species of dolphins and because they are large, they are considered apex predators, meaning they occupy the top slot in the food chain.
