Comb jelly - Bolinopsis infundibulum

Maximum length: 15 cm.

Appearance: The jelly in Bolinopsis infundibulum is completely transparent, except with some adults that can have a milkish white colour. On the exterior of the oblong body, four long and four short comb-rows are situated. These can shimmer with the colours of the rainbow. Bolinopsis infundibulum has two small tentacles that are transformed into fringes along the sides of the creature. The mouth is surrounded by two flaps; while the other end of the body is drawn out into a obtuse point. Compare with the sea-gooseberry and other comb-jellies.

Depth: From the surface to unknown depth.

Environment: Pelagic.

Misc: Bolinopsis infundibulum is very fragile and almost always breaks when handled. On the two large flaps small organisms fasten and thereafter are transported to the mouth with the small flickering hairs. Certain fish, e.g. lump suckers and other comb-jellies feed on Bolinopsis infundibulum. Individual adults produce both eggs and sperm which they release into the water where fertilization takes place. It is possible to see Bolinopsis infundibulum shine in the dark.

Classification: Bolinopsis infundibulum is a member of the comb jelly group (ctenophora).
