Enchodus, the extinct saber-toothed fish

Enchodus species were small to medium in relation to other fish of the era. One of the genus' most notable features are the large "fangs" at the front of the upper and lower jaws and on the palatine bones, hence the nickname, "the saber-toothed herring". These fangs, along with a long aerodynamic body and large eyes, suggest Enchodus was a predatory species.
