The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, 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. The usual size of mature female boas is between 7 and 10 ft (2. 1 and 3. 0 m) whereas males are 6 and 8 ft (1. 8 and 2. 4 m). 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. The largest documented non-stretched dry skin is deposited at Zoologische Staatssammlung München (ZSM 4961/2012) and measures 14. 6 ft (4. 45 m) without head. A report of a boa constrictor growing up to 18. 5 ft (5. 6 m) was later found to be a misidentified green anaconda.
