![]() Boa imperator, Boa nebulosa and Boa sigma have been elevated to full species status. ![]() Some appear to be based more on location, rather than biological differences. Several subspecies of Boa constrictor have been described, but many of these are poorly differentiated, and further research may redefine many of them. ![]() Other common names include chij-chan ( Mayan), jiboia ( Latin American), and macajuel ( Trinidadian). Within the exotic pet trade, it is also known as a "BCC", an abbreviation of its scientific name, to distinguish it from other boa species, such as Boa imperator or "BCI." Though all boids are constrictors, only this species is properly referred to as a "boa constrictor"-a rare instance of an animal having the same common English name and scientific binomial name.Īll subspecies are referred to as "boa constrictors", and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising species of both Boa constrictor and Boa imperator. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. Four subspecies are currently recognized. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. The boa constrictor is a member of the family Boidae, found in tropical South America, as well as some islands in the Caribbean. The red-tailed boa ( Boa constrictor constrictor) is a popular exotic pet.The boa constrictor (scientific name also Boa constrictor), also called the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. Farmers keep the snake around their fields and storage sheds to reduce the rodent populations. Slow moving and of a mild temperament, it is easily tamed. It kills by constriction, first grasping the prey and then using its coils to exert a deadly amount of pressure. In daytime it shelters in tree hollows, old logs, and animal burrows. It is mostly terrestrial but climbs into trees in search of birds. ![]() The boa constrictor is active from dusk to dawn, feeding on a wide variety of birds and mammals. The Argentine boa constrictor ( Boa constrictor occidentalis) is silvery gray with an unusual network pattern. In Boa constrictor ortonii, native to Peru, markings on the tail are red rather than brown, and the tail pattern is distinct. However, colours and markings frequently vary, not only among the subspecies but also among individuals in the same population. The basic coloration is deep brown-and-black markings-often in the shape of triangles, ovals, and joined ovals-against a pale brown-and-gray background. The head of the boa constrictor is long and triangular, with dark streaks from the eyes to the back of the jaw and another dark streak along the top. The number of boa constrictor subspecies is disputed, ranging from 6 to 11. The snake’s adult length is typically about 10 feet (3 metres), though individuals of more than 18 feet (5.5 metres) have been reported Central American boas rarely exceed 8 feet (2.4 metres). Though it thrives in tropical rainforests, it also inhabits savannas, cane fields, and semiarid scrublands. Its range is wide, from Argentina to northern Mexico.
