About the south american bushmaster

The South American bushmaster is a large pit viper found in the equatorial forests east of the Andes and on the island of Trinidad. Adults average 2 to 2.5 m long, and the largest recorded specimen was 3.65 m, making it the longest viper and the longest venomous snake in the Western Hemisphere. Its coat is yellowish, reddish or grey-brown with dark blotches that form inverted triangles along the sides. It lives in primary and secondary forest and preys mainly on rats and mice, as well as agoutis, opossums, squirrel monkeys, birds and frogs.

Many smaller facilities never apply, so “not accredited” isn't a verdict on its own. What accreditation means · How we check this
