Though
killer whales, also called orcas, are considered whales
by most people, they are actually members of the Delphinidae
(dolphin) family. Killer whales are excellent hunters
that a wide range of prey, including fish, seals, and
big whales such as blue whales. Despite their hunting
of other animals, free-ranging killer whales have never
been reported killing a human being.

Killer whales are extremely distinctive with jet-black
bodies and white patches usually over the eyes, under
the jaw, on the belly, and extending onto their sides.
Female killer whales can grow up to 26 feet (7.9 meters)
with a 3 foot dorsal fin while males are larger than the
females growing up to 28 feet (8.5 meters) with a 6 foot
(1.3 meters) dorsal fin. Killer whales have 48 to 52 teeth
that are large and conical shaped as well as slightly
curved back and inward.
