Biology     Glossary (e.g. epibenthic)

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). 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 (Ref. 833). Spawning began August which extended to November. High percentage of spawning males due to resorption of gametes was observed in December. No spermatogenic activity observed from late December to February. Gonad recovery started March, spermatozoa resorbed by nutritive phagocytes. Gonad recovery for females was slower compared to males (Ref. 93016).
