Morphology of Sea-Urchin Teeth

I. The Tooth of Stylocidaris affinis (Phil.) (Echinodermata, Echinoidea)

Abstract

The teeth of sea-urchins are not to be compared with the other skeletal-structures of echinoderms. The tooth is constructed of two rows of calcitelements, which are connected by secondary calcareous deposits forming the functional tooth. The surface of the tooth is covered by a crust of calcit. This fundamental construction is described from Stylocidaris affinis, which belongs to the archaic Cidaridae.
