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.
Look at the above image. The eyes are bulging and the head is mostly round. Then look at the image below. The head is flattened and the eyes focused. This is a defensive pose put on by the snake that is believed to mimic a pit viper. It takes on this position when it feels threatened.
These snakes can be found from Mexico to Columbia from sea level to 2400 foot elevations. In Costa Rica there are many variations of snail eaters including the lichen-colored and the banded.
