(2 specie in Swedish waters)

Comb jelly

Distribution in scandinavian waters

Maximum length: 16 cm.
Appearance: The jelly in comb jellies is more or less transparent, while the characteristic channels and branching are light purple, or somtimes brown to red. On the exterior of the oblong body, eight comb-rows of fused cilia are situated. These can shimmer with all the colours of the rainbow. Comb jellies have no tentacles. The large mouth covers most of the end of the comb-jelly. Compare with the sea-gooseberry and Bolinopsis infundibulum.
Depth: Sea-level to unknown depth.
Environment: Pelagic.
Misc: Comb jellies eat sea-gooseberries and Bolinopsis infundibulum. Certain fish, e.g. lump sucker, are among those that eat comb jellies. Individual adults can build both eggs and sperm. Fertilization takes place in the surrounding water. Comb-jellies shine brightly when dark.
Classification: Comb jellies are members of the ctenophora group.
