Heteroxenia is a genus of soft corals in the family Xeniidae.
The World Register of Marine Species lists the following species: [1]
Xenia is a genus of photosynthetic soft marine coral in the family Xeniidae. They resemble a mushroom, with "arms" coming out from the top that end in many-fingered "hands". It is unique among corals because of its ability to use its "hands" to "pulse" or push water away from the colony in a constant, grabbing motion. Common names include fast-pulse Xenia. Species of Xenia are sometimes referred to as pulse corals.
Turritella is a genus of medium-sized sea snails with an operculum, marine gastropod mollusks in the family Turritellidae.
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in captive aquaria.
The pulsating xenid is a species of soft coral in the family Xeniidae.
Goniodorididae are a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod molluscs in the order Opisthobranchia.
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms.
Zeadmete is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.
Bullia is a genus of sea snails, marine gastropod mollusks in the family Nassariidae, the Nassa mud snails or dog whelks.
Typhis is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Athleta is a genus of sea snails, marine gastropod mollusks in the family Volutidae.
Jujubinus is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Hespererato is a genus of small sea snails, marine gastropod mollusks in the family Eratoidae, the false cowries or trivias.
Trivirostra is a genus of small sea snails, marine gastropod mollusks in the family Triviidae, the false cowries or trivias.
Xeniidae is a family of soft coral in the order Alcyonacea.
Dendronephthya is a genus of soft corals in the family Nephtheidae. There are over 250 described species in this genus. They are sometimes kept in aquariums, but are notoriously difficult to keep, requiring a near constant supply of small foods such as phytoplankton.
Anthelia is a genus of soft corals in the family Xeniidae.
Cespitularia is a genus of soft corals in the family Xeniidae.
Sansibia is a genus of soft corals in the family Xeniidae.
Litophyton is a genus of soft corals in the family Nephtheidae.
The Hexanauplia constitute a class of crustaceans, comprising two groups: the Copepoda and the Tantulocarida. The former subclass Thecostraca was elevated to class rank and removed from Hexanauplia in 2021.
