Ratsnake With Tongue Out

By | August 6, 2021

This Ratsnake with tongue out was photographed at the Sequoyah National Wildlife Refuge in Oklahoma.

To sample the chemical environment, the tongue is flicked out of the mouth on a regular basis.

This method of chemical sampling enables these animals to detect non-volatile compounds that are not detectable by the olfactory system alone. This improved ability to detect chemicals has resulted in improved capacities to identify prey, recognize kin, choose mates, find shelters, among other things.
