					Pelagic (Ref. 99821).  Found on buoys and floating objects (Refs. 2767, 7484, 85157) and grows on cork lifebelt (Ref. 3534).  Also on keel of ships and driftwood.  Known as a fouling species (Ref. 81749).  Nonselective filter feeder; opportunistically ingests an array of zooplankton and fills its gut with sand when stranded on the beach.  Readily ingest large prey up to 5 mm in diameter (Ref. 106994).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the superorder Thoracica are mostly hermaphroditic.  Broadcast spawners, fertilization occurs in the mantle cavity.  Life cycle:  Eggs hatch into planktonic nauplii and leave the mantle cavity.  Afterwards, they undergo six naupliar instars succeded by nonfeeding cypris larva (settling stage) which later metamorphose into adults.
