Water Moccasin Crossing Gravel Road

I photographed this Water Moccasin crossing a gravel road at the Sequoyah National Wildlife Refuge in Oklahoma.

It seems like I’m not seeing very many Water Moccasins this summer like I normally do.

Why A Water Moccasin Is Called A Cottonmouth

A Water Moccasin is called a cottonmouth because of the white interior of its mouth, which it displays as a defensive warning when threatened. The white color gives the appearance of cotton, hence the name cottonmouth.

I was hiking an area of the Sequoyah National Wildlife Refuge in Oklahoma (4-27-2014) when I came across this Water Moccasin in my path. It was a cool morning so I thought this snake would be a little sluggish so I decided to approach it for a closeup. I walked up from behind it and got low for a shot. I was wrong! It wasn’t sluggish! It turns and lunged at me with its mouth wide open. This was more of a threatening move which worked because after taking a few photos I left it alone.

If your out hiking and especially hiking with a camera, be careful and watch for snakes. I have learned over the years to watch where I step as I look for wildlife to photograph.
