A cottonmouth moccasin, also known as a cottonmouth snake or water moccasin, is a venomous snake species native to North America, primarily found in wetland areas such as swamps and marshes. Scientifically referred to as Agkistrodon piscivorus, it belongs to the pit viper family.
The name "cottonmouth" originates from the snake's unique characteristic of displaying its white, cotton-like mouth when threatened or agitated, usually as a warning sign. This distinguishing feature has contributed to its alternative name "water moccasin," as "moccasin" refers to a type of shoe made from soft leather, similar to the texture of the snake's scales.
Cottonmouth moccasins are relatively large snakes, growing up to 4-5 feet long and possessing a stout, heavy body. They have dark-colored scales, often black or dark brown, making it easier for them to blend into their swampy surroundings. Their striking feature is the broad, triangular-shaped head, which is the primary indication of their venomous nature.
These snakes are expert swimmers and are well-adapted to their aquatic habitats, being proficient both on land and in water. They primarily feed on fish, but they are also known to consume various amphibians, reptiles, small mammals, and birds.

However, despite their venomous nature, these snakes typically exhibit non-aggressive behavior unless provoked or cornered, preferring to escape from potential threats rather than engage in confrontation.
