Are They Dangerous to Humans 

Amazon Tree Boa Teeth

The Amazon tree boa is not venomous, so it can’t kill you. But it is very aggressive and can inflict a painful bite without warning. You can get an infection from its bite, just like any other animal bites. You can get the worst injury when you pull back when it is latched onto you. It could cause tearing of your skin. Being relatively small, even as an adult, this is as much it can do to hurt you.

If you approach a captive snake at night, it will consider your hand as potential prey and inevitably bite. It might break your skin as it draws in blood. Once bitten, you need to clean and disinfect the wound. Most cases don’t need any medical attention.
