Black Dragons are a very rare melanistic form of the Asian water monitor lizard. Melanism means that its body produces an overabundance of the pigment melanin, making the animal nearly solid black (it's the opposite of albinism.)
Black Dragons can grow to become very muscular lizards, averaging 5-6 feet in length and weighing over 60 pounds!
Black Dragons are also called water monitors and spend much of their time living in the water.
It is natural for black dragons to hide and rest to digest their food. When hungry, it will come out for food and repeat the process. This species needs to eat more than most reptiles to support their high metabolism and sustain a huge amount of growth during the first two years of its life.
