Animals have evolved in amazing ways to ensure their survival in what is an unforgiving natural world. Some these defences include:
Sharp teeth / nails
The animal we are looking at today evolved to look like an adorable baby snake as a defense mechanism.
It looks completely like a snake and while it is cute to us, to other predators they would just see a snake and leave it alone for the most part.
As you can see it does not look like anything other than a small snake, just hanging out off a branch. But it is not even in the reptile family!
