Clownfish (Anemonefish)

Clownfish, also known as anemonefish, are colorful, tropical members of the damselfish family. All are "obligate symbionts" with large sea anemones - they can survive and reproduce only when living under the protection of their host anemone. Clownfish gain "immunity" to an anemone�s powerful sting, by gradually exposing more of their bodies to the tentacles, until they have acquired a protective coating of the anemone�s own mucus. Typically, an anemone plays host to a single pair of adult fish, and a variable number of juveniles.
