Distribution in scandinavian waters
|
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).
