Common Northern Boa
The Common Northern Boa (Boa constrictor imperator), is a species of boa native to Central America. It is one of the most common boa species found in captivity. In the wild it is found in Colombia, the Caribbean Islands, the Sonoran Desert of Mexico, and the Hog Islands, as well as other areas. There are fears that this species may be nearly extinct in the wild.
This is one of the smaller boa species, and averages 51 to 100 inches in length when fully grown. However, some specimens have been known to reach over 12 feet. They average about 13 pounds with females being significantly larger than males. In the wild, the lifespan is between 20 and 30 years, and 40 years in captivity.
The Common Northern Boa is hypomelanistic, meaning it has reduced melanin, and is more lightly colored, except for the tail, which is darker and is characteristic of this species. The tail color varies from salmon pink to orange in color.
