Clownfish
Finding Nemo, the Pixar movie introduced millions of people around the world the clownfish.
Twenty-nine species of clownfish live among the reefs from East Africa to French Polynesia
and from Japan to eastern Australia. Among scientists and aquarists, clownfish are also
known as anemone fish because they can't survive without a host anemone, whose stinging
tentacles protect them and their developing eggs from intruders. It's still a mystery exactly
how a clownfish avoids being stung by the anemone. Of the roughly thousand species of
anemones, only ten host clownfish. What's good for the clownfish is good for the anemone,
and vice versa. Clownfish spend their entire lives with their host anemone, rarely straying
more than a few yards from it
