The Anthozoa live only as polyps, while Scyphozoa live most of their life cycle as medusa. The Hydrozoa live as polyps, medusae, and species that alternate between the two (Towle 1989). Invertebrates belonging to the class Cubozoa are named for their cube-shaped medusae, which form the dominant part of their life cycle.
