Oikopleura cophocerca
''Oikopleura cophocerca'' is a species of small pelagic tunicate found in the surface waters of most of the world's oceans. It superficially resembles a tadpole and is surrounded by a transparent mucus net known as a "house".
==Description==
The trunk of ''Oikopleura cophocerca'' is oval and slightly arched and a few millimetres in length. A mouth at one end opens into a funnel-shaped pharynx and the anus is half way along the ventral surface. The endostyle is small and equidistant between the mouth and the anus. The branched ovary lies between the two testes. The tail is long, broad and muscular and contains remnants of the notochord as small, globular cells.〔Zoppy, Evelyn. 1971: Apendicularias de la Región Oriental de Venezuela. ''Studies on the Fauna of Curaçao and other Caribbean Islands'', 132:76-109. Lam I – VI.〕 The tail is attached just behind the anus and is bent forward to pass near the mouth. The tail has ventral and dorsal fins running along its length. However, because it is twisted through a right angle, it appears to have fins on its left and right sides and it undulates up and down rather than from side to side. The exoskeleton of this class of tunicates consists of a mucus net which is known as a "house" and surrounds the animal's body like a bubble.〔
