The cottonmouth snake gets its name from the cottony-white color inside its mouth. When angry or startled, the snake coils up, hisses, and shows this color to warn enemies to stay away. Those that don't heed the warning put themselves in harm's way of experiencing deadly venom. Exciting photographs enhance the English text that is translated into standard Latin-American Spanish, helping dual language learners to step into the world of the cottonmouth snake.
