31 Days of Monsters - Day 8: Ahuitzol

In Aztec legends, Ahuitzol is a aquatic, dog-like creature with slippery fur that can cut like razor blades. It has human hands instead of paws, and its long tail ends in a fifth hand which is uses to snatch prey from the shoreline. The bodies of Ahuitzol’s victims are found pounded into a rubbery mess and covered in slime. The only parts of a human that Ahuitzol consumes are the eyes, teeth and nails.
