The Orca Whale (or Killer Whale, as it is sometimes called) is actually a member of the dolphin family. They get the name "killer" not from their danger to humans, as I've heard they've only ever attacked humans in water parks (call that ironic), but from the diet and how they hunt. These whales/dolphins can hurl themselves onto beaches to capture penguins, and work together in packs, like wolves, to attack fish.
