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.
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
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.
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 ...
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.
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.
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 ...
