[3] Oxybelis fulgidus is found in mainland Latin America, primarily in Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname and Venezuela.

this behavior is reflected in other species of vine snake and it is believed that they are using their tongues as sights the way a cat uses its whiskers, as they move very quickly through branches and brush.

[1] An almost exclusively arboreal (tree-dwelling) species, the green vine snake remains high above the ground on tree branches, staring down awaiting any passing small animals.

When an appropriately-sized rodent, lizard, frog, bird, or other small animal is spotted, the snake follows it for a short distance, carefully analyzing the smells of the potential prey, and surrounding area, with its tongue.

If the snake has successfully stalked its desired quarry, it will attack, usually by biting into the head or back of the neck before lifting the prey 20–40 cm (8–15.5 in) off of the ground.

The vine snake is an opisthoglyphous (or "rear-fanged") species that possesses two larger, but blunted, peg-like teeth at the upper back of the mouth, which are slightly grooved on the sides to allow for delivery of a toxic salival fluid.

Once the prey is completely swallowed within the vine snake's body, it typically searches for a new resting place, usually at the highest point of a tree.
