Viper bat

The viper-bat is a small, flying, winged serpent found in the Earth Kingdom. Though generally diurnal, viper-bats typically avoid strong light and are most comfortable in dark, damp areas, making caves their most preferred habitat. Often living in large colonies, they are known to be easily aggravated and ill-tempered. Despite their naturally aggressive temperament, domesticated viper-bats are known to exist.

Anatomy
The viper-bat primarily resembles a rattlesnake in corpus, the only exceptions being the facial details and wings. They grow to be one to one-half meters in length and have a wingspan of about fifty to one hundred centimeters. Though their wings give them great speed and agility and their fangs a penetrating bite, it is unknown whether or not they are venomous, or what damage they are capable of. viper-bats bear distinctive dull red markings which run the length of their back, and have a softer sand-colored underbelly. Their tail ends in a crotalus, or rattle, which is of similar color to the belly. Though the mouth and eyes resemble that of a serpent, the ears and nose are more similar to that of a bat. The viper-bat has eight fangs that can be found within its mouth, and sand-colored tufts of hair in each of its ears. Moreover, the creature's facial structure is similar to a dog's, resembling the chihuahua most specifically.

Connection
The term viper refers to the Viperidae family of snakes, known for their venom and rather stocky build. Bats are mammals with the ability to fly, achieved through the use of webbed forelimbs resembling wings. Dogs are domesticated animals known for their versatility. The viper-bat exhibits both physical and behavioral similarities to all the aforementioned species.
