Venus flytrap sea anemone is a passive
suspension feeder, and orients itself on its often slender column so that it faces the upwelling current. Although usually considered
sessile, the Venus flytrap sea anemone sometimes moves, particularly as a juvenile. In 2004 a
mass mortality event occurred adjoining an oil pipeline off the
Ivory Coast. Large numbers of the
tunicate Pyrosoma atlanticum were involved, the moribund carcasses sinking to the seabed and accumulating in canyons and by the pipeline. Species found feeding on the gelatinous
detritus varied by depth. At a depth of few
fish were present, but Venus flytrap sea anemones were numerous. Other
necrophagous invertebrates at this depth included the sea anemone
Actinostola sp., the
sea pen Pennatula sp., the
sea urchins
Phormosoma sp. and
Mesothuria sp., brittle stars in the family
Ophiolepididae, the
penaeid shrimp Parapenaeus sp. and the
sea spider Colossendeis sp. ==References==
