[…]the Rosy Boa can be. They are live bearers, so breeders are spared the trouble of incubating eggs, and the 3-6 young typically produced are large enough to accept pink mice. Garter Snakes, Thamnophis spp. Over 30 species of these attractive, interesting snakes may be found in North America. Garter […]
[…]raise their own core temperatures and that of the egg clutch. Female Burmese Pythons lay 18-100 eggs after a gestation period of 60-150 days. The eggs hatch in 55-75 days. The hatchlings are 18-24 inches long (large enough to consume adult mice) and become sexually mature at a length of […]
