Boa constrictors are some of the world's most recognisable snakes. Their large size, docile nature (in captivity) and lack of venom has resulted in them being popular pets. However, in the wild, they still deserve respect and should NOT be interfered with by Pantanal visitors. Although not venomous, they can still give a very painful bite.
