Substrate Subclass Shell Reef Substrate
Substrate Group Crepidula Reef Substrate

Definition Shell Reef that is primarily composed of conglomerated Crepidula shells. While Crepidula are slowly mobile and do not cement their shells, the gregarious settlement of their larvae on conspecifics (Zhao and Qian 2002) can lead to very dense accumulations with a flat, reef-like texture as live shells build over dead shells.
