Status in the wild
International Union for the Conservation of Nature (IUCN) Red List status: Unlisted. They are threatened by commercial harvesting and by loss of habitat.
Found in Argentina, Bolivia and Paraguay. They are at home in gallery forests - evergreen forests that form along aquatic corridors - and in the trees of the surrounding savannahs.
Young birds, small lizards and occasionally amphibians.
- Female green snakes lay a scent trail when receptive. Males follow and the female may prolong the pursuit until is fully ready.
- This snake is an opisthoglyphous snake, meaning they possess weak venom, produced by an organ called a Duvernoy's gland and injected by a pair of enlarged teeth at the back of the maxillae, which normally angle backwards and are grooved to channel venom into the puncture.
- These snakes occur in two color morphs: brown and green. In some cases, the green morph can take on a bluish, sometimes turquoise, hue.
