Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Maximum length assumed to refer to total width (spinetip to spinetip) based on Ref. 87866. Occurs in shallow waters, especially in disturbed areas where it occurs in large aggregations. Feeds on algae. Associated with Stegopontonia commensalis (commensal) (Ref. 800).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
