						Often with small flat shell remnant hidden in mantle above digestive gland. Color ranges from translucent pale yellow to bright red; back covered with small white gland cells which secrete milky white secretion as a defense mechanism.					
				
				
						
			
			
			
			
				
					Assumed maximum length from Ref.  844. Known from depths of 0 to 150 m (Ref. 7727); and at shallow subtidal depths under boulders on reefs; shells to 40 m (Ref. 337) and in rock pools up to 2 m.  Hides under rocks at daytime, active at night (Ref. 844).   Reported as a scavenger (Ref. 866) and as feeding on a variety of sponges and three species of corals, i.e., Tubastrea coccinea, Leptastrea sp. and Porites lobata (Ref. 84066).
