The hardest animal substance known is the tooth enamel, which is the outer layer of teeth in vertebrates. Composed primarily of hydroxyapatite, a crystalline calcium phosphate, tooth enamel is highly mineralized and extremely durable, enabling it to withstand the pressures of chewing and grinding food. Its hardness surpasses that of bones and most other biological materials. Additionally, the unique structure of enamel provides excellent resistance to wear and damage.

Diamond is the hardest known natural substance, with a score of 10 on the Mohs scale of mineral hardness. It is made up of carbon atoms arranged in a crystal lattice structure, giving it its exceptional hardness and durability.
The hardness of diamond is a physical property of the diamond. The statement is also untrue as diamond is only the hardest known mineral, not the hardest known substance.
