Here's a breakdown:
* Teeth: Elephant molars are made of dentine covered in a thin layer of enamel, which is the hardest substance in the body. They have a unique structure with ridges that allow them to grind tough vegetation.
* Tusks: Tusks are actually modified incisor teeth that grow continuously throughout an elephant's life. They are made of dentine and a thin layer of enamel at the tip.
Fun fact: Elephants use their tusks for digging, lifting, fighting, and even stripping bark from trees.
