This Cottonmouth Water Moccasin came sneaking by while I was photographing a green heron on Fort Chaffee here in Arkansas.
Water Moccasin Facts
This species may be active during the day, as well as at night. However, on bright, sunny days, they are usually found coiled or stretched out somewhere in the shade. In the morning and on cool days, they can often be seen basking in the sunlight. They often emerge at sunset to warm themselves on warm ground (i.e., sidewalks, roads) and then become the very active throughout the night, when they are usually found swimming or crawling. Contrary to popular belief, they are capable of biting while underwater.
