Rear fanged venomous - same venom as boomslangs but smaller teeth. They are related to boomslangs like pines are to bulls - in fact the differences are very slight - slightly different shape of the head, one additional labial scale and dentition.
Arboreal, very visually oriented and smart. Live prey are dispatched very quickly with blood streaming from the eyes, nose and mouth.
This one is a real doll. Her mate is a complete idiot. Will blast out of the cage mouth agape and neck flattened charging at you. Won't calm down until you hook him and get him up.
A little discussion by Dr. Bryan Fry on their venom:
