EMERALD BOA Location: NE South America Status: Least Concern Facts:Female Emerald Tree Boas retain fertilized eggs inside their body while each young snake develops within their shell, being nourished by its yolk. When the young are fully developed they hatch inside the female — she gives birth to 10-20 live young that are approximately 30 cms (12 inches) in length. The young snakes are brick-red, orange, bright red or yellow in colour and they change to their characteristic green after a year. They have a strong prehensile tail which helps them to move around between the branches of trees. They spend their days coiled over branches with their head resting in the middle of the coils and they hunt at night. Boa Vision: The boa constrictor is nonvenomous and has color vision, some also have extended infra-red (IR) vision well beyond where humans  can see. This enables it to sense temperature differences of less than 0.03 degrees centigrade at a significant distance, and thus find live targets in dense rain forests. Their IR vision system is being studied by the military to see how such a detector, useful for night vision, can function without being cooled to a very low temperature. ____ Fact Source: http://www.theanimalfiles.com/reptiles/snakes/boa_emerald_tree.htmleyesight fact: http://www.eyedesignbook.com/ch3/eyech3-f.html —- houseofmoon: hissssss
