The tiny Rubber Boa is related to the giants of South America, the Anaconda and Boa constrictor. Rubber Boas are constrictors that squeeze to death their prey. They are considered rather lethargic, harmless snakes that resemble large worms. They have blunt heads and tails. When encountered in the field, a boa will coil into a tight ball displaying its tail, protecting its head. Rubber boas are good climbers and swimmers, but prefer to burrow in loose soil
