It is an epibenthic species found on reefs (Ref. 95730), that feeds by grazing (Ref. 96498). It is also found in sheltered, localised populations, on fronds, rock surfaces, undersides of rocks, boulders, seaweeds, and shallowly buried under gravel (Ref. 124689).
Life cycle and mating behavior
পরিপক্কতা | প্রজনন | ডিম ছাড়া | Eggs | ডিম্বধারন ক্ষমতা | 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.
