It was proposed that this species played an important role in the transformation of the coral community in reefs of Rhomboidal Cays, Belize. It used to be dominated by Acropora cervicornis, but was transformed to be dominated by Agaricia tenuifolia due to the herbivory of this species. It resulted to promoting the settlement and growth of Agaricia in the area (Ref. 86570).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
