Boa Constrictor Identification

Boa constrictors primarily live in rainforest clearings and range from Central to South America. They are large, carnivorous snakes with distinctive patterns on their heads and bodies.

  1. Colors and Patterns

    • Boas are brown or cream with dark brown bands. The bands usually become brighter towards the tail, and there may be small, dark spots covering the entire body. The head is characterized by dark stripes extending from the snout to the back of the head.

    Eyes

    • The eyes are usually the same color as the head, and the stripes from the snout may run through them.

    Teeth

    • Boa constrictors are non-venomous snakes and do not have fangs; instead they have rows of small, curved teeth.

    Length

    • Adult boa constrictor snakes average 8 to 10 feet in length, and in rare cases may exceed 12 feet. Newborn boas are usually 24 inches.

    Weight

    • Boa constrictors are thick-bodied snakes that can weigh up to 60 pounds.

    Males and Females

    • Female boa constrictors are usually larger than males, but the tails of males may be longer.
