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]
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]

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 ...
