COTTONMOUTH
Agkistrodon piscivorus
DESCRIPTION
Cottonmouth (Agkistrodon piscivorus) is commonly known as the Water Moccasin due to its aquatic habits. This venomous snake is characterized by its thick body, triangular head, and distinctive white mouth lining, which it displays when threatened. Cottonmouths are semi-aquatic and are often found in swamps, marshes, and along the banks of rivers, where they play a crucial role in the ecosystem as both predator and prey.
FUN FACTS
- Cottonmouths are one of the few venomous snakes that are known to swim with their heads above water, making them easily recognizable in their aquatic habitats
- They are also known for their unique behavior of 'playing dead' when threatened, which can sometimes confuse potential predators
