Ahuizotl

Ahuizotls are beasts that originate from South America, however, they have now spread worldwide.

Appearance
Ahuizotls look like a strange mash up of a lot of creatures. They look mostly canine in appearance, with waterproof fur that, when dried out, becomes spiny in appearance (which give them its name, meaning "spiny aquatic thing"). They also have simian-like front paws/hands, which are fully prehensile, and their long tails also have fully functional hands on the ends.

Behavior
Ahuizotls are reclusive creatures, tending to live in pools of water, and keeping to themselves except during mating season. They are ambush predators, preferring to lie in wait until a creature comes near it's home pool, then unleashing a sneak attack, dragging the unlucky prey under the water. However, they don't eat the whole of their prey, preferring to eat their eyes, teeth, and claws/hooves/fingernails. Then the ahuizotl in question leaves the rest of the carcass to whatever scavengers tend to live near their pool. Despite their fearsome appearance, just like other mammals, they are actually quite good parents, with the female protecting her 5-6 pup litter until they are old enough to take care of themselves.
