Hydrozoa
There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 20 species of Cubozoa, and in Hydrozoa there are about 1000-1500 species that produce medusae (and many more hydrozoa species that do not).
The hydrozoa refers to the taxonomic class of predatory animals and colonial animals that live in salt water. The members of hydozoa are related to corals and jellyfish.
