Anthozoa. Anthozoa is a subphylum of marine invertebrates which includes sessile cnidarians such as the sea anemones, stony corals, soft corals and sea pens. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as planktons. The basic unit of the adult is the polyp; this consists of a cylindrical column topped ...
Hexacorallia is a class of Anthozoa comprising approximately 4,300 species of aquatic organisms formed of polyps, generally with 6-fold symmetry. It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. [2]
Octocorallia. Octocorallia (also known as Alcyonaria) is a class of Anthozoa comprising over 3,000 species [1] of marine organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians (sea fans and sea whips) within three orders: Alcyonacea, Helioporacea, and Pennatulacea. [2]
Corals are colonial marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
Sea anemone. Sea anemones (/ əˈnɛm.ə.ni / ə-NEM-ə-nee) are a group of predatory marine invertebrates constituting the order Actiniaria. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia.
Aiptasia is a genus of a symbiotic cnidarian belonging to the class Anthozoa (sea anemones, corals). Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic ...
Sea pen. Sea pens are marine cnidarians belonging to the order Pennatulacea, which are colony -forming benthic filter feeders within the class Octocorallia (subphylum Anthozoa). There are 14 families within the order and 35 extant genera; it is estimated that of 450 described species, around 200 are valid. [1]
