Diagram 1b- Fisheriferious Omnivorous

The teeth of this species of Fisher are akin to the shark and are not attached to the jaw, but embedded in the flesh. In this particular species, they are constantly replaced throughout the Fisher's life. All Fishers have multiple rows of teeth along the edges of their upper and lower jaws (see diagram). New teeth grow continuously in a groove just inside the mouth and move forward from inside the mouth on a “conveyor belt” formed by the skin in which they are anchored.

In some Fishers, rows of teeth are replaced every 8–10 days, while in other species they could last several months. The lower teeth are primarily used for holding prey, while the upper ones are used for cutting into it. The teeth range from thin, needle-like teeth for gripping pizza to large, flat teeth adapted for crushing gobstoppers.

By "prey" I assume you mean "candy" (let the reader understand.)
