Agkistrodon piscivorus Cottonmouth

They are called cottonmouth for their fluffy white mouth insides that they show out when threatened


Venomous cottonmouths, also known as Water moccasins, are semi-aquatic snakes. During the warmer months, they reside in swamps, wetlands, lakes, and floodplains. They frequently inhabit upland environments away from watery habitats in the spring and fall. Almost always, cottonmouth fish swim with their heads above the surface.

They stay close to their home range and live alone. Cottonmouths hunt by attacking, biting, and injecting their prey with venom. Additionally, they keep the victim in their coils until it stops scurrying. Cottonmouth numbers appear to be steady across their range, and they are neither an endangered nor a threatened species.
