Shark's Tooth Pendant - Fish

Product History

Fish were vertebrates (backbones animals) that live in water. Fish without jaws or teeth appeared at the end of the Cambrian Period, about 480 million years ago. Jawless fish fed by sucking tiny pieces of rotten flesh from the sea floor. Fish developed jaws and teeth 420 million years ago. This allowed them to catch and eat larger animals and move around more freely than jawless fish.

During the Devonian Period, about 410 million years ago, fish had heavy armour of bony plates and scales. Most of these fish eventually died out, but some, including the first sharks and ray-rimmed fish, have modern relatives.
