Eirenidae is a family of hydrozoans.
The following genera are recognized within the family Eirenidae: [1]
Nausithoidae is a family of jellyfish.
Atolla is a genus of crown jellyfish in the order Coronatae. The genus Atolla was originally proposed by Haeckel in 1880 and elevated to the monotypic family level, as Atollidae by Henry Bigelow in 1913. The six known species inhabit the mesopelagic zone. The medusae possess multiple lobes called lappets at the bell margin. Medusae also have eight tentacles, alternating with eight rhopalia, and twice as many lappets occur as tentacles.
Leptothecata, or thecate hydroids, are an order of hydrozoans in the phylum Cnidaria. Their closest living relatives are the athecate hydroids which are similar enough to have always been considered closely related, and the very apomorphic Siphonophora which were placed outside the "Hydroida". Given that there are no firm rules for synonymy for high-ranked taxa, alternative names like Leptomedusa, Thecaphora or Thecata, with or without the ending emended to "-ae", are also often used for Leptothecata.
Conica are a cnidarian suborder of the Leptomedusae. They make up the bulk of their order; their internal relationships are not well resolved, and most of the roughly 30 families are not yet assigned to a superfamily.
Buprestinae is a subfamily of beetles in the family Buprestidae, containing the following genera in the tribes Anthaxiini, Buprestini, Chrysobothrini, Melanophilini, and Xenorhipidini:
Agalmatidae, or Agalmidae, is a family of siphonophores.
Pandeidae is a family of hydroids in the class Hydrozoa. Like other jellyfish there is usually a mature medusa form which is pelagic and reproduces sexually and a hydroid or polyp form which is often benthic and reproduces asexually by budding.
Aeginidae is a family of hydrozoans in the order Narcomedusae. The family comprises 6 genera and 8 species.
Cuninidae is a family of hydrozoans in the order Narcomedusae. They have dome-shaped bells and tentacles set above the undulating margin of the bell. Their gastric pouches contain the gonads situated in line with the tentacles, the number of pouches being the same as the number of tentacles. The pouches do not extend below the points of origin of the primary tentacles. Members of some genera have a peripheral canal system and others do not. No radial canals or secondary tentacles are present.
Aequorea is a genus of pelagic hydrozoans in the family Aequoreidae.
Filifera is a suborder of hydrozoans in the order Anthoathecata. They are found in marine, brackish and freshwater habitats.
Pelagia is a genus of jellyfishes in the family Pelagiidae. It is currently considered as monotypic with one species, Pelagia noctiluca(Forsskål, 1775).
Eirene is a genus of hydrozoans in the family Eirenidae.
Tima is a genus of hydrozoans in the family Eirenidae.
Eleutheria is a genus of hydrozoans belonging to the family Cladonematidae.
Eutonina is a genus of cnidarians belonging to the family Eirenidae.
Linuche is a genus of cnidarians belonging to the family Linuchidae.
Cytaeididae is a family of cnidarians belonging to the order Anthoathecata.
Amphidorini is a tribe of darkling beetles in the family Tenebrionidae. There are about 7 genera in Amphidorini.
