They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head.
Several other predators of the pit viper (mongooses and hedgehogs) show the same type of relationship between snakes, which helps to support the hypothesis that venom has a very strong defensive role along with a trophic role. Which in turn supports the idea that predation on the snakes can be the arms race that produces snake venom evolution. [31]

Unlike most pit vipers, P. flavoviridis is oviparous and lays eggs, rather than bearing live young. [6] Mating takes place in early spring and up to 18 eggs are laid in mid-summer. The hatchlings, which emerge after an incubation period of 5–6 weeks, are 25 centimetres (10 in) in length and look the same as the adults. [7]
