This beautiful snake is found in the rainforests across a large area of South America. Unlike its more famous relatives, the Boa constrictor and the Anaconda, it only reaches a length of about six feet. It has the longest fangs in proportion to its size of any living snake. Females give birth to as many as 20 young, which do not attain their bright green color until they are around nine months old. Until then, they are orange or dark red. In recent years it has been regularly bred in captivity.
