Ratsnake With Tongue Out

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.

Ratsnake Crawling Over Rocks

This Ratsnake was crawling over rocks on the auto tour road at the Sequoyah National Wildlife Refuge in Oklahoma. When I was a kid, I knew these snakes as Chicken Snakes. Occasionally, Rat Snakes are found near chicken coops and hen houses, where they may often feed on chicken eggs.
