How to identify Eyelash viper

The eyelash viper stands out immediately thanks to its bright colours. Its scale pattern ranges from rich green to yellow and rust red and may be marked with fine speckles or bold blotches. Particularly distinctive are the raised scales above the eyes, which look like small horns.

Its compact, rounded body shape is usually under 80 centimetres long and it rarely weighs more than 200 grams. The eyelash viper has a conspicuously strong prehensile tail that lets it hang securely from branches. Compared with similarly coloured tree snakes you can recognise it by the “horn” above the eye and its thick build.
