Pleurobrachia pileus is a small, globular or ovoid comb jelly up to about 2.5 cm (1 in) in length. It has a pair of long tentacles that are used to catch prey and can be retracted into sheaths. The tentacles are up to twenty times the length of the body and are fringed with filaments along one edge. [2]
This comb jelly lives freely on soft sediment, unlike other benthic ctenophora which are typically parasitic. [3] They are hermaphroditic like most platyctenids, and are also capable of asexual reproduction via body fission and regeneration.
The comb rows bearing bands of cilia, typical of comb jellies, are absent, but one end of the animal bears a pair of well-developed, retractable tentacles that can be extended for feeding. The underside of the comb jelly is a "creeping sole", formed from the everted lining of the pharynx, [3] and on this it can move over the surface of the ...
Cydippida is an order of comb jellies. They are distinguished from other comb jellies by their spherical or oval bodies, and the fact their tentacles are branched, and can be retracted into pouches on either side of the pharynx. The order is not monophyletic, that is, more than one common ancestor is believed to exist. [1]
Lobata is an order of transparent marine invertebrates belonging to the phylum of Ctenophora in the class Tentaculata, and are commonly referred to as comb jellies or sea gooseberries. [1] There are currently 19 extant known species in the order of Lobata. [2] Members of Lobata exhibit a compressed body in the vertical plane and a pair of oral ...
Beroidae is a family of ctenophores or comb jellies more commonly referred to as the beroids. It is the only known family within the monotypic order Beroida and the class Nuda . They are distinguished from other comb jellies by the complete absence of tentacles, in both juvenile and adult stages.

Tentaculata is a class of comb jellies, one of two classes in the phylum Ctenophora. [1] [2] 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.
