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]
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. It has a pair of long tentacles that are used to catch prey and can be retracted into sheaths.
Euplokamis is a genus of ctenophores, or comb jellies, belonging to the monotypic family Euplokamididae. [2] 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 ...
Pleurobrachia bachei is a selective carnivore and its feeding habits are analogous to other ambush "sit and wait" predators, such as the orb-weaving spider.When searching for prey the Pleurobrachia swims with its oral pole forward to set its tentacles.
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 ...
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 ...
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 ...
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.
