Amphimedon compressa

Notes: Thickly encrusting, massive, flabellated or branching, from dark brown to purple to bright red, sometimes dark orange; all apparently seem the same species, with a reticulation of spongin fibers filled with oxea spicules. Dark specimens may be confused with black Amphimedon complanata (Duchassaing, 1850), also pictured here.
