Facts:

  • Range from the Sonoran desert in Mexico through Central America and outlying islands, to far northern Peru.
  • May forage in the trees but are mainly terrestrial and live in hollow logs, mammal burrows, etc.
  • Eat rodents, birds, iguanas, and monkeys
  • The boa’s loosely hinged jaws can be stretched far apart, enabling it to swallow animals with bodies much larger in diameter than the boa’s head.
