This non-venomous animal is a stout-bodied snake that feels like rubber with a blunt head, no noticeable neck and tail common to burrowers. The tail is prehensile. The coloration is plain brown above, yellow below, without pattern or with a few dusky flecks on the lower sides. Sometimes it is called a "two-headed snake" because the tail is shaped like the head. The last few vertebrae of the short, thick tail are fused. The eye pupils are vertical.
Secretive. The rubber boa is a good swimmer, burrower (in sand, loose earth or forest litter), and climber, at home underground and in trees. It is often found in or beneath rotting logs or under rocks. When threatened it curls into a tight ball, raising its tail above the coils and waiving it in a characteristic striking motion.
These snakes ovoviviparous (meaning the eggs are retained inside the female\\\\\\\'s body until hatched). Two to eight young usually born from August to November. They are seven to eleven inches long are born each time. The young are pinkish to light brown above, yellowish below.
The rubber boa endures cold much better than most snakes. It can tolerate a temperature as low as 54 degrees. It travels farther north than any other boa with the possible exception of two Asian boas. It is the only boa in Utah.
