Amphibious predators that look like a cross between an eel and a frog

Whippersnappers are amphibious predators, that look like a cross between an eel and a frog. They have long, slender bodies, covered in slimy, mottled skin, long mouths filled with needle-like teeth, and large, unblinking eyes, well adapted to see clearly in the murky water of their homes. Using their four, powerful webbed feet and muscular tails to propel them through the water with alarming speed. In combat, whippersnappers will either try to bite with their sharp teeth or slap with their powerful tail. They are generally not aggressive towards anything as big as a human, but they will defend themselves if provoked or cornered.
