Found on fine sand that is superficially muddy, on sand between coarse and fine grade, and on plain coarse sand (Refs. 103193, 129602). Genus Clypeaster feeds by crushing sand-sized particles and producing finer sediments (Refs. 108727, 129602). Burrows in coarse or fine sediment (Ref. 129602).
Life cycle and mating behavior
половая зрелость | размножение | нерест | 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.
