Mudfangs are hideously ugly, pop-eyed and needle-toothed fish about eight inches long that can survive out of water for a time. They hunt on the shallows and mudflats of some southern islands in large swarms. Mudfangs move about by hopping on their leglike front fins, and can hop faster than a man can run in the sticky, sucking morasses that they dwell on. These fish lie buried up to their eyeballs in mud most of the time, almost invisible, but when prey enters their range they burst out of hiding and attack en masse. They will attack creatures larger than themselves, and can pull down wading birds, wild pigs, sea lizards, even humans by sheer force of numbers.
