Boa constrictors can grow up to 10 feet long and weigh 60 pounds. They live in Central and South America in habitats like rainforests, grasslands, and deserts. Boas eat a variety of prey that increases in size as the snake grows from young mice and frogs to adult monkeys and pigs. To hunt, boas capture prey in a tight grip called constriction and swallow it whole. Boas mature at 3-4 years old when they are about 6 feet long.
