5. Boa constrictor (Boa constrictor)
Boa constrictor ranks 5th in our list of most common snakes in America. It is the commonest of boa snakes, which include 10 subspecies, and it is the fifth most common shake in America. It is a non-venomous constrictor snake, among one of the biggest snakes in the world. Their massive bodies average about 3 meters in length, and up to 45 kg of weight. Their coloration varies and depends on the environment, making them masters of disguise, usually being grayish with brown and red patches. Even though they are terrestrial species, boa constrictors are excellent swimmers, so no prey can escape them. Nevertheless, they are very calm and slow snakes that would very rarely attack, rather they produce a whistling sound in order to warn and drive away the intruders.
