About the Red-Tailed Boa

Geographic Range:

Class: Reptilia
Order: Squamata
Family: Boidae
Genus: Boa
Species: constrictor

The red-tailed boa is named for its reddish tail, although it's primarily tan and brown. It's a large snake, growing as long as 10 feet and weighing up to 60 pounds. Since it's a constrictor and not venomous, it feeds by using its powerful coils to tightly constrict its victims, cutting off blood flow to the heart and causing death. The red-tailed boa’s jaw unhinges and stretches, allowing the boa to swallow medium-sized and large prey, after which it doesn't need to eat again for weeks or months.
