Maximum depth from Ref. 106595. Intertidal (Ref. 106595) to sublittoral (Ref. 106593). Found on rocky shores (Refs. 106372, 106591, 106593, 106597). Also on grounds consisting of gravel encrusted with calcareous red algae (Ref. 106597). Herbivorous grazer (Ref. 106997). Grazes on encrusting coralline algae on rocks, on dead Posidonia oceanica leaves and their epiphytes, and on the rhizomes and roots of the seagrass when accessible (Ref. 106595). Scrapes the external part of rhizomes and consumes the roots entirely (Ref. 106997). Bioeroder since it feeds on any coralline substrate (Ref. 106598).

Life cycle and mating behavior Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Các trứng | Sự sinh sản | Ấu trùng

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.
