Butterflyfish depend on living coral for shelter and food.

Many species feed directly on living coral polyps, and others on the tiny invertebrates around the corals, or on the tube feet or tentacles of larger invertebrates such as Sea Cucumbers, Starfish, Sea Anemones or Jellyfish.

Coral Biology

Corals are small animals (polyps) that are closely related to sea anemones and jellyfish.

Most corals create colonies, by growing a large rocky skeleton that we see as a solid coral rock. The soft bodied polyps live in the outer edge of this skeleton, on top of the empty skeletons of previous generations. Only the outer layer of a coral boulder is alive.
