A close-up of the noble fan mussel (Pinna nobilis), nestled among Mediterranean Posidonia seagrass.

The fan mussel (Pinna nobilis) is the largest bivalve mollusc in the Mediterranean Sea. It features symmetrical, triangular shells with a reddish mother-of-pearl interior and a heavily encrusted exterior. This species lives anchored vertically in sandy bottoms or within Posidonia oceanica meadows, at depths ranging from 3–4 meters to over 30 meters. It can reach a maximum length of 90 centimeters.
