Are Black and Green Snakes Venomous?
Black and green snakes can be venomous, mildly venomous, and non-venomous.
Many arboreal black and green snakes are venomous or mildly venomous. Some of them can kill people while those that are mildly venomous only cause pain and skin-level irritation.
Non-venomous species can still bite as a lack of venom doesn’t guarantee a docile nature in black and green snakes.

Black and green snakes can be terrestrial, arboreal, aquatic, or semi-aquatic.
The nature of these snakes can be elusive as many of them are nocturnal and secretive. Only a small number of these snakes are diurnal and easy to spot as they don’t come out during the day.
