Boinae
Quick Summary
The Boinae are a subfamily of nonvenomous constricting snakes within the family Boidae. This subfamily includes well-known species like the boa constrictor, tree boas, and anacondas, found in the American tropics, as well as other genera from Madagascar and the southwestern Pacific islands.1
Boinae members vary in size, with some species reaching over 4 meters (13 feet) in length, such as the green anaconda. The boa constrictor inhabits diverse environments from Mexico to Argentina. Tree boas, like the emerald tree boa, are arboreal and possess heat-sensing organs in their lips to aid in hunting. Most boines are terrestrial or arboreal, preying on mammals and birds, which they capture through constriction.1
