Corals are large colonies of small animals called polyps.
These polyps reside within a cup-like calcium carbonate
skeleton. They have a central opening surrounded by
tentacles which can be extended to feed on phytoplankton
in the water column. Corals are a member of the phylum
cnidaria, which also includes jellyfish and anemones.
