The Sheepshead is a species of fish that is found in the Southern parts of the United States. They feed on shrimp, sandfleas, clams, and crabs. What do these things have in common? They tend to have harder shells.
In order to be able to eat them, the Sheepshead has developed stubby teeth that look human! The stubby form of their teeth allow them to more easily crush their prey. Check out the source for more creepy pics!
