Definition: | Is a multi-tissue structure composed of dentine, enameloid and tooth pulp. The tips of the ceratobranchial 5 teeth form before the ceratobranchial itself (3.0 mm NL). As they grow ventrally, they meet the perichondrally ossified surface of ceratobranchial 5 and become firmly ankylosed to the bone. Ceratobranchial teeth are the only teeth present in zebrafish and other cypriniforms. |
