    Nocturnal during the warmer months, Aruba Island rattlesnakes are active in early morning and late afternoon during the rest of the year. Their diet includes small rodents, birds and lizards.

  • Life History

    These snakes have small litters of live young. The young are eight inches in length and have fully functioning venom glands at birth. They can live as long as 20 years.

    The rattle at the end of the tail warns off enemies and acts as a first line of defense for the Aruba Island rattlesnake.
