Snakes! They look like an alien species, and some of the things they’re capable of will convince you they’re not from this planet! They see in Predator-like infrared, they shed their skin, and have you seen that weird-looking tongue?

Snakes don’t use their tongue like we do. Think about it: you really don’t have time to taste something if you can only swallow food whole without chewing it. Instead of using it to taste, snakes smell with their tongues. That’s why they always flicker it in and out – they want to catch nano-particles in the air that will tell them if their prey or some kind of danger is nearby.
