Caption
Mock vipers not only look like tree-dwelling vipers but also act like them. Intriguingly, they have a fake ‘fang’ in the front of their mouth, which befools a predator into thinking that they possess venom fangs during an open-mouthed threat display. However, there is also an actual fang in the back of the jaw, which carries a weak venom effective only on their lizard prey.
