A killer whale (also called an orca) is a marine mammal.[1] The largest member of the dolphin family, it was characterised by its black body, white underbelly, and the white, eye-like patches above both of its actual eyes.[1]

An orca is one possible corporeal form of the Patronus Charm.[2]


In 1994, Dudley Dursley was described as having reached "roughly the size and weight of a young killer whale," prompting the Smeltings school nurse to urge his his mother and father to place him on a strict diet.[3]
