Cloudy Snail Eater (Sibon nebulatus) Lichen-Colored Snail Eater (Sibon longifrenis)

A Cloudy Snail Eater and a Lichen-colored Snail Eater Snake found in Limon Costa Rica

We found this average sized snail eater while taking down our bamboo passion fruit trellis. He was lodged in one of the corners about 7-8 feet off of the ground. That let us know that this is an adult snake because the juveniles of this species are terrestrial. These snakes are not harmful to humans they eat mostly snails and slugs using their special jaws and teeth. They use their needle like teeth to extract snails from their shells while their bottom jaw holds and moves the shell to help the process.
