Common Garter Snake, ConnecticutI photographed this garter snake in my backyard a few summers ago. The snake had just swallowed a toad and was moving very slowly, allowing me a close approach with my macro lens. Snakes use their forked tongues to collect chemical information from two different locations at once. This helps with navigation — in sort of a 3D kind of way — when looking for food, a mate and whatever else snakes are into these days. Nikon D850 with Nikkor 105mm macro lens, ISO 800, f/7.1 at 1/640th of a second.
