King snakes are nonpoisonous constrictors. They like to eat other snakes, even rattlesnakes and coral snakes. The venom from these poisonous snakes does not harm a king snake, and that is why it is called the king of all snakes. Students will read about the cream-colored eggs in a female king snake’s clutch, the length of babies when they hatch, and the patterns and colors of these snakes’ skin.
