Also known as Savigny’s long-spine sea urchin. Diet: Algae
Max. Size: 25 cm
Fun Fact: Associated with Stegopontonia commensalis. 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. In some regions of the world specific fishes larvae species can hide between their spines in order to get protected from predators.
