Alligar

Overview
Razorjaws are large, vicious fish that live primarily in freshwater environments. They aren't particularly social creatures, but a single razorjaw is far more dangerous than an entire group of muckrippers. They consider anything in the water to be their prey, including any unlucky creature that happens to fall in. - (Text from the press kit)
