Depending on the phase the species can be striped instead.\nBlue Spotted Sea Urchin Astropyga radiata occurs in the tropical Indo-Pacific Ocean from the African coast to Australia and to Hawaii in a depth range from 0 to 60m, usually 10 to 30m, max. test diameter 20cm. \nThe species is often found in lagoons and bays where the substrate is sand, shingle or coral rubble.
