					Fished along Chilean coasts since the 1960's and has been used as a food source since pre-Columbian times. It is found on rocky substrates from the intertidal to a depth of 340 m, and it feeds on Macrocystis sp. (Ref. 87801).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the class Echinoidea are gonochoric.  Fertilization is external.  Brooding is common, eggs are held either on the peristome, around the periproct or deep into the concavities on the petaloids.  Life cycle:  Embryos develop into planktotrophic larvae (echinoplateus) and live for several months before they sink to the bottom using their tube feet to adhere on the ground where they metamorphose into young urchins.
