The boa constrictor (Boa constrictor), also called red-tailed boa, is a species of large, heavy-bodied snake. It is a member of the family Boidae found in North, Central, and South America, as well as some islands in the Caribbean. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Ten subspecies are currently recognized, although some of these are controversial. This article focuses on the species Boa constrictor as a whole, but also specifically on the nominate subspecies B. c. constrictor.
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.
All subspecies are referred to as "boa constrictors", while the nominate subspecies, B. c. constrictor, is often referred to specifically as the "red-tailed boa". Within the exotic pet trade, it is also known as a "BCC", an abbreviation of its scientific name, to distinguish it from other boa constrictor subspecies such as B. c. imperator, which is also regularly, and erroneously, referred to as a "red-tailed boa" or "common boa".
Other common names include chij-chan (Mayan),jiboia (Latin American), and macajuel (Trinidadian).
The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python and Burmese python, and can reach lengths from 3–13 ft (0.91–3.96 m) depending on the locality and the availability of suitable prey. Clear sexual dimorphism is seen in the species, with females generally being larger in both length and girth than males. As such, the usual size of mature female boas is between 7 and 10 ft (2.1 and 3.0 m), and 6 and 8 ft (1.8 and 2.4 m) for the males. Females commonly exceed 10 ft (3.0 m), particularly in captivity, where lengths up to 12 ft (3.7 m) or even 14 ft (4.3 m) can be seen. A report of a boa constrictor growing up to 18.5 ft (5.6 m) was later found to be a misidentified green anaconda.
