The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales are found in all oceans, from Arctic and Antarctic regions to tropical seas.
WOO AT LAST! Been working on this one for a little while. Orcas are such facinating animals. They are the second most-widely distributed mammal on the planet (after humans), and they fill an ecological niche similar to our own. Not only do they vary.
