It has one extant order, [[Stauromedusae]] (stalked jellyfishes), and one extinct order, Conulatae.<ref>{{Cite web|url=http://marinespecies.org/aphia.php?p=taxdetails&id=265044|title=WoRMS - World Register of Marine Species - Staurozoa|website=marinespecies.org|language=en|access-date=2018-03-21}}</ref> The extinct order is largely unknown and described as a possibly [[cnidaria]]n clade of marine life with shell-like structures, the [[Conulariida]]. Staurozoans are small animals [1–4 cm (0.4–1.6 in.)] that live in marine environments, usually attached to seaweeds, rocks, or gravel.<ref>G., A. (1970, January 01). Staurozoa.

Few staurozoans are found in warmer tropical and subtropical water environments of the Atlantic, Indian, and Pacific Ocean basins, but most are known from the Northern Hemisphere.<ref>G., A.
