Biology     Glossary (e.g. epibenthic)

Found subtidally (Ref. 102838). Inhabits hard substrates by boring on rocks in shallow waters (Ref. 800). It is also found on fore-reefs (Ref. 87903). Feeds on algae and small invertebrates. Associated with Athanas indica, which hides between its spines (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).
