Body Traits

The feature that they are names for are several pointed scales over each eye that looks like eyelashes. They are typical pit-vipers with big triangle-shaped heads, up and down-shaped (vertical) pupils and pits between the nose holes (nostrils) and eyes that can sense heat (prey). They can be many colors, depending upon where they live. They can be yellow, orange, olive-green, tan, brown, or gray. They can have blotches or bands in different coloring. They are up to 2.5’ long. This is small compared to other rain forest snakes. They have the ability to wrap around branches and hold on (prehensile tail). This suits their life in the trees. They have sharp fangs that are quite poisonous. Their bites result in several deaths every year.


They are active at night (nocturnal). They live in the trees (arboreal). They often sit perched on above ground tree roots and watch for prey to come walking by.
