Organisms of a Subtidal Sand Community in Southern California
A long-term study of a subtidal sand community on the exposed coast of California has revealed a highly structured, diverse assemblage of macroscopic, epifaunal organisms. It is dominated by a few species of relatively large, long- Uved suspension feeders, particularly the sand dollar Dendraster excentricus. Along the depth gradient from 2.6 m to 13.1 m there are three faunal zones with the sand dollars occupying most of the middle zone. The community is composed of about 45 common species; the seaward zone has the greatest diversity and number of predators. Nearly 90 invertebrate and more than 30 fish species were recorded during the study.
