The Orca is found in all oceans and seas
of the world, from the deepest waters to the coast. These
whales occur less in waters far from land and more often
in colder waters rich in food. The degree of ice cover limits
their polar distribution and they do not normally migrate
from warm to cold waters like the baleen whales do - but
they are hardy enough to survive in many different conditions
and are found in tropical waters as well.
The Orca or "killer whale" is
a toothed whale that is an efficient predator, known to
attack even young blue whales. The Orcas' only enemy is
human beings. These communal whales live in small, close-knit,
life-long pods and have one blowhole. The killer whale is
the biggest dolphin in the family of dolphins and is sometimes
called the "wolf of the sea" because its behavior
is similar to that of the wolves.
