					This is the largest African pyurid, some specimens are larger than 10 cm across (Ref. 2673). Benthic, marine; aggregations on sediment free rocky substrate; solitary on sandy substrate (Ref. 1134).  It forms aggregates or mats in rocky intertidal environments (Ref. 3464).  Also found in pier piles and reefs.  Feeds on plankton or particles (Ref. 101296).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the class Ascidiacea are hermaphroditic; both cross- and self-fertilization is typical.  Life cycle:  Eggs develop into lecithotrophic larva before metamorphosing into benthic adults.
