Biology     Glossary (e.g. epibenthic)

Harvestable size is around 9-10 cm test diameter (4-5 years in age) (Ref. 121955). Found in relatively high energy environments on open rocky intertidal and subtidal shores (Ref. 121802). Herbivorous grazer in nearshore habitats (Ref. 121801). Kelp forest species (Ref. 121804). Found in concentrated amount at the apex of the holdfast of the giant kelp Macrocystis pyrifera (Ref. 121803).

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.
