Species: Louisiana pine snake (Pituophis ruthveni)

Status: Endangered (EN)

Interesting Fact: The Louisiana pine snake is non-venomous, instead using its body to crush its prey.

More information:

One of the rarest and least understood snakes in the United States, the Louisiana pine snake occurs in longleaf pine forests in parts of Louisiana and eastern Texas. This large snake relies on pocket gophers for food, hunting them in their underground burrows and pinning them to the side of the burrow to kill them. It also eats some other small mammals, as well as birds, bird and turtle eggs, and lizards. The Louisiana pine snake spends most of its time underground, usually relying on pocket gopher burrows for shelter and for hibernation sites. This snake has the smallest clutch size of any North American snake, at just three to five eggs. However, its eggs are larger than those of other North American species.

The Louisiana pine snake’s longleaf pine habitat is one of the most threatened ecosystems in the United States, with only 3% of the original forest now remaining. Much has been logged or degraded by urbanisation, agriculture and the cultivation of other pine species. Changed fire regimes have also altered the structure of the habitat, making it less suitable for the snake and its prey. The Louisiana pine snake is often killed on roads and may be threatened by collection for the pet trade. Recommended conservation measures for this snake include protecting its remaining populations, maintaining and restoring its habitat, and undertaking more research into its populations and behaviour. The Louisiana pine snake is a candidate species for potential listing on the U.S. Endangered Species Act, and is legally protected in Texas. A reintroduction project is underway for this rare and elusive species.
