How did water moccasin and cottonmouth get its name?

The water moccasin, also known as the cottonmouth, derives its name from its distinctive white mouth lining, which it displays when threatened. The term "moccasin" is believed to originate from the Algonquian Word for "shoe," reflecting the snake's body shape. The name "cottonmouth" emphasizes the snake's unique defensive behavior of opening its mouth wide to reveal the white interior, which can startle potential predators. Together, these names highlight the species' physical characteristics and behavior.
