Mediterranean Sea Anemone

Scientific name : Anemonia viridis

Columnar body, ending with about 200 tentacles that usually hide it, reaching a maximum length of 20 centimetres.
The mouth is in the middle of the tentacles; on the other side there is the basal portion, that fix the animal to the substrata. The body is yellowish or brown, due to symbiotic algae hosted in the animal’s tissues, while the tentacles have usually purple tips.

It lives in shallow waters, where the strong light allows the algae to have photosynthesis, and feed on small fishes and crustaceans, that capture with the tentacles.

Associated organisms
It is often associated with Inachus phalangium, a small maijdae, in a symbiotic rapport.
