Class Hydrozoa

Family Milleporidae

Fire corals are reef-building hydroids with hard skeletons and embedded zooxanthellae.  They differ from stony corals in having a smooth surface and tiny pores with thin hairs that deliver painful stings.  Reproduction involves a free-living medusa stage.  Colonies are especially common in shallow water with good circulation.  None occur in Hawaii.

All coral skeletons illustrated are from scientific collections taken prior to 1998.
