Enameloid, also known as durodentineorvitrodentine, is an enamel-like tissue found in many fish. It is the primary outer component of shark odontodes (teeth and dermal denticles). Although the origin of enameloid is debated, it is probably homologoustodentine rather than true enamel, despite its enamel-like strength and development. The term covers any hyper-mineralized tissue with an organic "scaffold" consisting of ectodermal and ectomesenchymal proteins.[1][2][3]
