Madagascar tree boa  (Sanzinia madagascariensis)

This medium-sized constrictor occurs in two colour variations. Prevalent mainly in the eastern half of the range is the green to greyish-green form which tends to be about two thirds of the size of the mandarin form which is yellow, orange and brown and occurs in some parts of the western side of the range (2) (4). As with many boa species, there are heat-sensitive pits around the mouth, used for hunting at night (2).
