This Isn't Really A Snake, But The Truth Is Even Weirder And Still Freaky

So you're walking through the wilds of Trinidad and you happen to look up — right into the leering face of a viper. But then you notice that there's something a little weird about this viper.

Before you head for the hills, take a closer look. There's a better chance you're actually looking at one of these.

#1 Meet the Dynastor darius caterpillar. Actually, meet its chrysalis.

Nature is pretty weird sometimes, and things aren't always as they seem. So the next time you see something freaky on a weekend hike, it might actually be a teeny bug playing a joke on you.

#3 When it comes time to grow up, they create a chrysalis around themselves like all good caterpillars do. Inside, they undergo their 13-day transformation into a butterfly. But while that's happening, they're vulnerable to predators for obvious reasons. That's why they developed this awesome disguise.

#4 To a passing predator, the chrysalis looks like the native Gaboon pit viper, which is much more formidable than a caterpillar.

And if that doesn't work, the caterpillar will sway from side to side, just as a snake would when sizing up its prey. Even though it's completely wrapped up, the caterpillar can still sense outside stimuli.
