Of all the animals on the planet, fish show some of the most diversity among all their many and varied species. One such trait that many fish tend to have are very, very unique teeth. Some fish have incredible canines for skewering their prey while other have smaller rows of sharp teeth for taking tiny nibbles of things. The wolffish has nearly every kind of tooth possible. It’s got large canines in the front to grab hold of their prey as well as rows of flat teeth designed to crush their food as it makes its way down their throats.
