Puerto Rican boa

The Puerto Rican boa (Chilabothrus inornatus), most commonly known as Culebrón ("big snake"), is a large species of boa endemic to Puerto Rico. It is a terrestrial and arboreal snake with a pale brown to dark brown coloration. It grows to 1.9 m (6.2 ft) in length. It feeds on small mammals such as rodents and bats, birds and sometimes anole lizards. Like most boas, it is viviparous (bearing live young) and kills its prey using constriction.
