Chupacabra

Chupacabra, or "Goat Suckers," are creatures that average about four feet in height and are roughly humanoid, though they are not believed to be sentient.  They have long heads with snouts that end with a disc shaped mouth that is full of needle-like teeth.  They also are covered with a thick coat of spines which can take on colors of the surrounding environment, allowing them a very effective form of camouflage.

Some biologists believe that chupacabras existed before Serpentfall, but their camouflage enabled them to evade detection, observation, and capture.
