Popis
Shell large, frequently distorted. Sculpture of low, narrow, widely spaced radial ribs, and finer commarginal ribs, nodose at intersections. Periostracum heavy, with dense, broad, sharply pointed setae. Byssal gape distinct, narrow. Length to 100 mm.
This species is a member of the Panamic fauna, but in warm-water years larvae have been known to settle as far north as San Pedro, California (33.7°N) [CAS]. It is unlikely that reproducing populations are present north of Isla Cedros, Baja California (28.2°N) [LACM]; from San Felipe, Baja California (31.0°N) [LACM] to Paita, Peru (5.1 °S) [CAS], and the Islas Galapagos (1.0°S) [LACM], in the intertidal zone to 120 m. Recorded as early as the Pliocene in western North America.
