Scyphozoa

Helmet jelly Periphylla periphylla, copyright Erling Svensen.


Belongs within: Medusozoa.
Contains: Ulmaridae.

The Scyphozoa are a group of cnidarians including the typical jellyfish and related taxa, united by the presence of polydisc strobilation in metamorphosing polyps (further modified in some rhizostomes), rhopalia and ephyrae. Most scyphozoans have a life-cycle alternating between a sexually reproducing planktonic medusa and an asexually reproducing benthic polyp (Daly et al. 2007).
