Western Pacific: from Japan to East Indies, Fiji and Samoa.
Occurs in shallow intertidal areas at depths of 0 to 20 m. Buries in the sand. Feeds by non-selective deposit feeding (Ref. 800). 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).
