Green vine snake – a diurnal (active during the day) and mildly venomous tree snake.
They are known to be found in India, Sri Lanka, Bangladesh, Burma, Thailand, Cambodia and Vietnam. (source – Wikipedia)
They are slow moving, relying on camouflaging as a vine in foliage. The snake expands its body when disturbed to show a black and white scale marking, that is what you see in this image.
Apparently, this species is viviparous, giving birth to young that grow within the body of the mother, enclosed within the egg membrane.
Another interesting fact is that, eyes of a green vine snake work together, focusing on the same image. This type of vision is called binocular and it is typical for humans. However, in most species of snakes, eyes work separately one from another.
In the image: We found this guy at night, he didn’t like being disturbed (photographed with flash strobes). Otherwise a calm snake, displayed aggression warning us – it was his sleep time. We quickly got couple of decent shots and moved on with respect.
