Why A Water Moccasin Is Called A Cottonmouth

By | May 3, 2020

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.

How I Got The Shot – Water Moccasin

I was hand holding a Canon EOS 7D with a Canon EF 100-400 mm f/4.5-5.6L IS lens attached.
