![]() ![]() melanogaster Langhammer, 1983: a nomen dubium ĭescription Size and weight Several other subspecies have been described at different times, but currently, these are no longer considered to be valid subspecies by many herpetologists and taxonomists. ![]() The subspecific name ortonii is in honor of American naturalist James Orton. South America except for the ranges of the other three subspecies Boa imperator, Boa nebulosa, Boa orophias and Boa sigma have all been elevated to full species status. Some appear to be based more on location rather than on biological differences. Several subspecies of Boa constrictor have been described in the past, 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." 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 the species Boa constrictor and Boa imperator. Only one other vertebrate animal shares this trait, the theropod dinosaur Tyrannosaurus rex. Though all boids are constrictors, only this species is properly referred to as the "boa constrictor" - an instance of an animal having the same English common name and scientific binomial. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. ![]() ![]() A staple of private collections and public displays, its color pattern is highly variable yet distinctive. The species is native to tropical South America. The boa constrictor is a member of the family Boidae. The boa first strikes at the prey, grabbing it with its teeth it then proceeds to constrict the prey until death before consuming it whole.The boa constrictor (scientific name also Boa constrictor), also known as the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. However, they do hunt, particularly in regions with a low concentration of suitable prey, and hunting generally occurs at night. Boa constrictors are ambush predators, so often lie in wait for an appropriate prey to come along, when they attack. It makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might be otherwise. Like all snakes, Boa constrictors in a shed cycle are more unpredictable, because of the substance that lubricates between the old skin and the new one. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. These snakes strike when they perceive a threat. Boa constrictors often occupy the burrows of medium-sized mammals, where they can hide from potential predators. As semi-arboreal snakes, young Boa constrictors may climb into trees and shrubs to forage however, they become mostly terrestrial as they become older and heavier. They are nocturnal, but they may bask during the day when night-time temperatures are too low. Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate. ![]()
