4/C – Cerianthid anemone - Cerianthus membranaceus

This animal, with a vermiform body, lives in pipes that it secretes itself, of pergamenous consistency (up to one meter long) and totally or almost totally embedded in the sediment. The crown of tentacles, which captures the food, is the only visible part of the animal. It can be found in rocky-sandy-muddy mixed beds, among Posidonia and also in caves, from few meters up to around 40/45 m deep, always in waters rich in sediment.
