Filifera is a suborder of hydrozoans in the order Anthoathecata. They are found in marine, brackish and freshwater habitats.
Members of this suborder are characterised by the filiform tentacles of the polyps which do not terminate in knobs. The rose corals, family Stylasteridae, secrete calcium carbonate exoskeletons around a network of stolons. [1]
According to the World Register of Marine Species, the following families are found in this suborder : [2]
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.
Rhopalonematidae is a family of hydrozoans. The family comprises 15 genera and 36 species.
Narcomedusae is an order of hydrozoans in the subclass Trachylinae. Members of this order do not normally have a polyp stage. The medusa has a dome-shaped bell with thin sides. The tentacles are attached above the lobed margin of the bell with usually a gastric pouch above each. There are no bulbs on the tentacles and no radial canals. Narcomedusans are mostly inhabitants of the open sea and deep waters. They can be found in the Mediterranean in large numbers.
Solmundella is a genus of hydrozoan in the family Solmundaeginidae. It is monotypic, with the single species Solmundella bitentaculata.
Agalmatidae, or Agalmidae, is a family of siphonophores.
Aequoreidae is a family of hydrozoans. There are approximately 30 known species found in temperate and tropical marine coastal environments. Aequoreids include Aequorea victoria, the organism from which the green fluorescent protein gene was isolated.
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.
Solmarisidae is a family of hydrozoans in the order Narcomedusae. The name is sometimes spelled "Solmaridae".
Bougainvillia is a genus of hydroids in the family Bougainvilliidae in the class Hydrazoa. Members of the genus are characterised by having the marginal tentacles of their medusae arranged in four bundles. Some species are solitary and others are colonial but all are filter feeders. They are found in the Southern Ocean, having a circumpolar distribution, but some species also occur in the Northern Hemisphere, possibly travelling there as polyps on the hulls of ships.
Limnomedusae is an order of hydrozoans.
Olindiidae is a family of hydrozoans in the order Limnomedusae. They have a polyp phase and a medusa phase. The polyps are generally small (1 mm) and solitary, but a few species are colonial. They have a varying number of tentacles and can reproduce by budding. In the largest species, the medusae can grow to 15 cm (6 in). Centripetal canals may be present or absent and the radial canals are unbranched. The gonads are beside the radial canals, except in Limnocnida, where they are on the manubrium. The fertilised eggs develop into planula larvae which become polyps. These multiply asexually or can bud off medusae. In some species, medusae are only produced when the water temperature exceeds a certain level. Most species are marine, but several can also be found in brackish water and a few, notably Craspedacusta and Limnocnida, are found in fresh water.
Corynidae is a family of hydrozoans in the order Anthomedusae.
Hydractiniidae is a cnidarian family of athecate hydroids.
Aequorea is a genus of pelagic hydrozoans in the family Aequoreidae.
Capitata is a suborder of Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria.
Solmaris is a genus of diminutive hydrozoans.
Cystonectae is a suborder of siphonophores. It includes the Portuguese man o' war and Bathyphysa conifera, sometimes called the "flying spaghetti monster."
Physonectae is a suborder of Siphonophores. In Japanese it is called 胞泳.
Bassia is a monotypic siphonophore genus in the family Abylidae. The genus only contains the bioluminescent species Bassia bassensis.
