Parrotfish Teeth: Stiff Biominerals Whose Microstructure Makes Them Tough and Abrasion-Resistant To Bite Stony Corals
Published 2017“…Its enameloid is a fluorapatite (Ca<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>F) biomineral with outstanding mechanical characteristics: the mean elastic modulus is 124 GPa, and the mean hardness near the biting surface is 7.3 GPa, making this one of the stiffest and hardest biominerals measured; the mean indentation yield strength is above 6 GPa, and the mean fracture toughness is ∼2.5 MPa·m<sup>1/2</sup>, relatively high for a highly mineralized material. …”
