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]
The comb jellies have more than 80 different cell types, exceeding the numbers from other groups like placozoans, sponges, cnidarians, and some deep-branching bilaterians. [ 23 ] Ranging from about 1 millimeter (0.04 in) to 1.5 meters (5 ft) in size, [ 22 ] [ 24 ] ctenophores are the largest non-colonial animals that use cilia as their main ...
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.
Beroe cucumis is a predator and mostly feeds on other comb jellies, particularly Bolinopsis infundibulum; these are pulled into the large mouth and swallowed whole. [3]The comb jelly Mnemiopsis leidyi is an invasive species originally native to the western Atlantic coastal waters that was introduced into the Black Sea in the 1980s, with deleterious results to the ecosystem.
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.
