Description
A living specimen of Decatopecten radula, a species of scallop, resting on a sandy and gravelly seabed. The shell is fan-shaped, bivalve, and exhibits prominent radial ribs. Its surface is covered with a greenish-brown layer, likely algae or other epibionts, and intricate white, worm-like patterns. The shell margin is slightly undulating, reflecting the ribbing.
