This is the largest Mediterranean bivalve mollusc and it may reach 100 centimetres in length. It is found on sandy beds, standing vertically with a third of its body buried in the sand. It usually lives in areas in meadows of seaweed, especially Posidoniaoceanica and Cymodocea nodosa.

This mollusc is on the list of endangered species, although its population in the sea around the Ebre Delta has increased, thanks to the fact that the seaweed meadows are protected on this coast.
