The orca
or killer whale is a toothed whale that is an efficient
predator, even attacking huge young blue whales. Their
only enemy is human beings. Orcas live in small, close-knit,
life-long pods and have 1 blowhole. The killer whale
belongs to the family of dolphins and is the biggest
dolphin. It is sometimes called the "wolf of the
sea" because its behavior is similar to that of
wolves.
