Boas - General Description

Boa constrictors are non-venomous boa species found in mostly Central America, South America and some islands in the Caribbean. As unusual as it sounds, the common name is the same as the scientific name. Its color pattern is highly variable depending on the location of the sub-species. Boa Constrictors may grow to become quite large, some even as large as 20 feet. Among all of the snakes on SnakeEstate.com you'll find that our Boa Constrictor database offers the most valuable information. Adult sizes vary between the subspecies, although those found in northern South America reach the greatest lengths among all of the subs.

The tail is slightly prehensile and there are no thermoreceptive labial pits around the mouth, boas tend to move rather slow on the ground.

The color pattern consists of a ruddy brown ground color, becoming a rich brick red on the tail. Dorsally, the ground color is overlaid with a series of large tan-colored saddles that become lighter towards the tail. Here, the saddles break up into half rings of a pale cream color in vivid contrast with the red.
