It is common for female individuals to exceed 10 feet (3.0 m), particularly in captivity, where lengths of up to 12 feet (3.7 m) or even 14 feet (4.3 m) can be seen. As such, the average size of a mature female boa is between 7–10 feet (2.1–3.0 m), whilst it is 6–8 feet (1.8–2.4 m) for the males. There is clear sexual dimorphism seen in the species, with females generally being larger in both length and girth than males. The Boa constrictor is a large snake, although only modestly sized in comparison to other large snakes such as the reticulated python and Burmese python, and can reach lengths of anywhere from 3–13 feet (0.91–4.0 m) depending on the locality and the availability of suitable prey. Other common names include "chij-chan" (Mayan),"jibóia" (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 constrictor subspecies such as the Boa constrictor imperator which is also regularly, and erroneously, referred to as a "red-tailed boa". constrictor, is often referred to specifically as the "red-tailed boa". (The distinction is shared with Tyrannosaurus rex.)Īll subspecies are referred to as "Boa constrictors", while the nominate subspecies, B.
Though all boids are constrictors, only this species is properly referred to as "Boa constrictor" a rare instance of an animal having the same common and scientific binomial name.
