Staurozoa
Staurozoa is the class of Medusozoa, jellyfishes & hydrozoans. It has one extant order: Stauromedusae stalked jellyfishes. a fossil corporation called Conulariida has been introduced as aorder, although this is highly speculative. The extinct design is largely unknown and sent as a possibly cnidarian clade of marine life with shell-like structures, the Conulariida. Staurozoans are small animals 1β4 cm or 0.4β1.6 in that represent in marine environments, ordinarily attached to seaweeds, rocks, or gravel. They pull in a large antitropical distribution, a majority found in boreal or polar, near-shore, as living as shallow waters. Few staurozoans are found in warmer tropical together with subtropical water settings of the Atlantic, Indian, and Pacific Ocean basins, but most are required from the Northern Hemisphere. Over the years their number of style has increased, thus modification now this is the said to realise an estimated 50 species.
