Keropins

Amphibious demonoids that live within forests and swamps. The Keropin develops from a tadpole state to a large, man eating-beast. It has an omnivorous diet and can swallow almost anything it can fit into it's stomach.

A Keropin will swallow it's prey whole and digest it into materials to use for its eggs, usually having messy sex with it beforehand. While not the strongest, they are very resilient in body and versatile in water and on land, making them very proficient predators.
