Benthic; depth range 0 - 90 m (Ref. 81020)
Climate / Range
Indo-Pacific: from Indian Ocean Tahiti and from Japan to South Pacific Islands.
Reported to have the broadest range of color morphs in the family Diadematidae (Ref. 2932). Most common color morphs throughout Indo-Pacific were the white (inerambulacral spines) and brown (test and ambulacral spines) and the completely brown color morph (Ref. 2929).
Inhabits shallow coral and coral rubble areas at depths of 1 to 40 m (Ref. 800). Feeds on algae (Ref. 2938). 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).
