Diagnosis

Cydippidae with an egg-shaped body with but little lateral compression, the tentacular diameter being only slightly wider than the sagittal. In this respect Pleurobrachia differs markedly from Mertensia, wherein the sagittal diameter is much narrower than the tentacular. The tentacle bulbs are placed within deep clefts, midway between the sides of the stomach and the general surface of the body. The 2 long, lateral tentacles give rise to numerous, simple, filamentous side branches. The 8 meridional canals extend under and along the 8 rows of cilia and end blindly, not forming a closed system of tubes.
