Boa constrictor
This species does well in captivity, usually becoming quite tame. It is a common sight in zoos. Captive longevity is 20 to 30 years, with rare accounts of over 40 years, making them a long-term commitment as a pet.  Proper animal husbandry is the most significant factor in captive lifespan. Though still exported from their native South America in significant numbers, it is widely bred in captivity.
