The image shows a snake, specifically a type of
venomous viper often referred to as a pit viper due to the presence of heat-sensitive pits that detect infrared radiation. The snake has its mouth open and appears to be hissing or vocalizing. It's important to note that this behavior can indicate aggression, fear, or communication with other snakes. The snake is not alone in the image; it seems to be on a leafy branch or plant, which is likely part of its
natural habitat.
