Bolinopsis infundibulum is a medium-sized, oblong shaped comb jelly. It may reach up to 15 cm in length. It is completely transparent or, more rarely, a milkish white colour. It swims with eight longitudinal combs, four long rows and four short rows, that give the comb jellies (ctenophores) their characteristic shimmering appearance. These combs consist of plates of transverse rows of hairs that beat in waves downwards, which produces the shimmering effect. These plates are phosphorescent at night. Bolinopsis infundibulum only has two small tentacles with fringes along its sides.Bolinopsis infundibulum is carnivorous and feeds on copepods, euphausids and other zooplankton. Prey are funneled on to the mucous-covered loral flaps with the aid of ciliated structures known as auricles. Cilia transport the captured food to the mouth (Gamble, 1977).
