Sample Locations:

Agelas dilatata

Notes: Light brown to tan fans, thin to rather thick; with many round oscules on the upper (exposed) surface. The underside (cryptic) is smooth, often riddled with dark zoanthids, and sometimes having a few scatteres oscules. Some specimens may take a flat-branching form, like that of some A. cervicornis (Schmidt, 1870), also pictured here, but the latter usually arise from a narrow, cylindrical base. Spicules are acanthostyles.
