Tentaculata

Tentaculata is a class of comb jellies, one of two classes in the phylum Ctenophora. The common feature of this class is a pair of long, feathery, contractile tentacles, which can be retracted into specialised ciliated sheaths. In some species, the primary tentacles are reduced and they have smaller, secondary tentacles. The tentacles have colloblasts, which are sticky-tipped cells that trap small prey.

Platyctenida, also known as benthic comb jellies, is an order of comb jellies in the class Tentaculata. Platyctenids display a generally benthic lifestyle in contrast to most ctenophores being largely pelagic. Platyctenids display widely differing morphological characteristics from their pelagic counterparts, being highly flattened on their oral-aboral axis and having lost many key traits associated with the phylum.

Cestidae is a family of comb jellies. It is the only family in the monotypic order Cestida. Unlike other comb jellies, the body of cestids is greatly flattened, and drawn out into a long ribbon-like shape. The two tentacles are greatly shortened, and two of the four ciliated comb rows are reduced. The unusual body form allows the animals to swim by means of muscular undulation, as well as by using their cilia. The largest species, belonging to the genus Cestum, can reach in length.

Euplokamis is a genus of ctenophores, or comb jellies, belonging to the monotypic family Euplokamididae. It shares the common name sea gooseberry with species of the genus Pleurobrachia. After being originally described by Chun (1879), the family Euplokamididae was expanded by Mills (1987) due to the discovery of a new species, Euplokamis dunlapae. Further research indicated that Euplokamis should be identified from Mertensiidae due to the rows of combs and some compression. They may also be distinguished from the genus Pleurobrachia due to their more elongated shape. Additionally, various ada

Thalassocalyce is a genus of ctenophore, or comb jellies, known from the California Coast, Gulf of Mexico, and west north Atlantic. It is represented by a single species, Thalassocalyce inconstans, which is the only species in the family Thalassocalycidae and the order Thalassocalycida. T. inconstans is a pelagic ctenophore typically occurring in upper-mesopelagic depths, but has been observed at depths up to 3,500 m in Monterey Canyon.
