Benthocodon is a genus of hydrozoans of the family Rhopalonematidae. The genus contains two known species: Benthocodon hyalinus and Benthocodon pedunculatus, however due to the small size and red pigmentation, they can easily be confused with related genera. Unlike many hydromedusae, these jellyfish do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. The genus Benthocodon can be found near the sea floor in the Pacific Ocean from Antarctica to California to the Arctic Ocean.

Muggiaea is a genus of siphonophores in the family Diphyidae. Members of this family are colonial siphonophores with two nectophores (swimming bells) arranged one behind the other, but in the genus Muggiaea, the posterior nectophore is absent. The anterior one has a complete dorsal ridge. The somatocyst (extension of the gastrovascular system) is very close to the nectosac (central cavity with muscular walls) wall.

Hydrichthys is a genus of colonial marine hydrozoans formerly placed in the family Hydrichthyidae but is now included in the family Pandeidae. The polyps of members of this genus are parasitic. The polyp attaches itself to a fish, and in one species exhibits hyperparasitism by attaching itself to a copepod, itself the parasite of a fish.

Csiromedusa medeopolis is a species of hydrozoan described in 2010. It was discovered in the estuarine waters of the River Derwent near to the Commonwealth Scientific and Industrial Research Organisation's Marine and Atmospheric Research branch in Hobart, Tasmania, Australia. C. medeopolis has been described as presenting a new family and genus as well as species.

Kephyes is a genus of cnidarians belonging to the family Clausophyidae.

Trichydra is a monotypic genus of cnidarians belonging to the monotypic family Trichydridae. The only species is Trichydra pudica.

Apolemia is a genus of siphonophores. It is the only genus in the monotypic family Apolemiidae.

Laomedea is a genus of Cnidaria of the family Leptothecata. The genus was described by Lamouroux in 1812.

Lineolaria is a genus of hydrozoans belonging to the family Lineolariidae.

Gymnangium is a genus of hydrozoans belonging to the family Aglaopheniidae. The genus was first described in 1874 by British naturalist, Thomas Hincks He describes the species of the genus as having unprotected gonothecae, whence the genus name, which derives in part from the Greek work for naked, γυμνός. In 1923, Eberhard Stechow, nominated the type species as Halicorniara montagui.
