Though it is a favorite of the pet industry, it has no morphs.

Are They Dangerous to Humans 

Dumerils Boa Constrictor

Like any other wild animal, it bites when it feels threatened. But being non-venomous, a bite with its fairly small teeth will only leave a scar without causing any harm. Though it may seem frightening for its imposing size, it loves to be left alone.

As pets, they are pretty docile and readily feed. But they are prone to stress that may cause them to stop eating, leading to health issues. Also, some may be bitier and need patience to be tamed.
