7 Superpowered Animal Senses You Won't Believe Are Possible

It knows who walked down the street last night at 11PM, what the soles of their shoes were made of, the brand of cigarette they were smoking. Your eyes see this...

... and tell you Ingrid had a secret admirer last spring when they fixed the sidewalk. Your dog knows Ingrid is buried under there and that you shouldn't turn your back on the doorman who smokes Pall-Malls.

Fortunately for the sake of this article, and unfortunately for the sake of everyone who's afraid of bears, the silvertip grizzly's sense of smell is seven times stronger than that of the bloodhound.

You see, silvertips can smell your fear, just like any other scary-ass predator. But unlike most predators, they can smell your fear over distances measured in double digits. In miles. These bears can smell a carcass from 18 miles away. When a silvertip enters a clearing, you're screwed even if you left 48 hours before. And if you're still there, all that sweating, pissing yourself and crapping your pants while you ran away will be laying down a neon-colored trail for the bear to follow until you get tired.

Part of the reason for this is because, despite what some scientists would have you believe, predators are scavengers as well, and the ability to smell a dead body close to 20 miles away goes a long way toward helping get a free meal. Since bears scare the shit out of every other living thing (except maybe wolverines), being able to smell someone else's kill is like being a 250-pound bully in eighth grade; no one is going to fuck with you when you walk up to him and take his food. Not even entire packs of wolves.

We've shown you before just how scary-advanced jumping spiders can be -- they're like nature's tiny modern velociraptors. But they aren't just better at hunting flies than you are; they also have vision that would put the most sharp-eyed fighter pilot to shame.

They have what is called tetrachromatic vision. That means that where we see three primary colors, they see four. In a matter of speaking, their eyesight goes to 11.

This is actually a much bigger deal than simply thinking the Pink Floyd laser light show is 25 percent more fabulous than the rest of us. In much the same way your computer monitor uses red, blue and green to create images covering the spectrum from white to black to yellow (and colors that require a shot of Jaeger just to maintain manliness after mentioning, like chartreuse and fuchsia), adding a fourth color opens an entire new realm of perception.

That's because the fourth color they see is ultraviolet, which actually appears like an entire extra spectrum to creatures that can see it. Law & Order: SVU fans might recognize ultraviolet light as the stuff that reveals how many times the corpse was ejaculated upon. There are many things besides body fluids that would be perfectly visible if you had the eyes of a jumping spider.

For instance, it would open your eyes to the history behind objects. UV light is what revealed that ancient Greek statues were painted, not white, and made it clear that dino bones were hollow a lot earlier than we figured it out with our stupid three-color eyes. We suppose it's a small price to pay for being able to sleep in a hotel room.

For the jumping spider, it's even better. While some animals are perfectly invisible under normal light, they become night-and-day obvious in ultraviolet. This means it's hunting insects that are blissfully unaware that their evolutionarily awesome camouflage is completely useless against the death machine running or leaping towards them on eight giant legs. Even the normally black emperor scorpion, which is not coincidentally what the Hells Angels named their biker gang before they knew it was taken, glows a bright blue-green in UV vision.

On the bright side (if you're a bug), a jumping spider's primary eyes have a field of vision that only ranges from two to five percent. Unfortunately, they have eyes placed around their heads, so they can actually see in 360 degrees.

And they can see your ass hiding against that flower.

The only thing scarier than spiders with super-vision would be something like a Navy SEAL with 360-degree vision outside the normal spectrum, but that's impossib- Oh shit ...

There's a particular species of starfish that has calcite crystals embedded in its skin, surrounded by chromatophores (color-changing cells found in the octopus and cuttlefish as well) that allow it to not only change color in ways a chameleon would envy but also to control the amount of light passing into the calcite crystals. Oh yeah, those crystals? They are tied to nerve bundles designed to detect light and are formed into lenses. This makes the entire creature, in a manner of speaking, a single eye the size of a man's open hand.

The whole array of lenses acts like an interferometer, with each of the separate crystals acting together like the facets of a compound eye, their individual images combining to form a single clear picture.

To add strange to weird, the light-collecting lenses focus light on the skeleton of the creature, which then redirects it to "windows" of clear material in the skeleton that focus the light onto the optic nerve bundles, which then relay the information to a ring of nerves around the central disc of the body. With their entire body essentially acting as a complex fiber-optic network, it's not totally surprising that they have to eat with their assholes.

So, in the end, probably not worth it.

The monarch butterfly's northward migration every spring looks like the sort of poorly planned bullshit you expect from mass animal migrations, with hundreds of millions spreading out across North America, presumably wherever they damn well please.

In August, they fly back south, and things get spooky. First of all, there's the fact that all hundred million fly directly to the same tiny patch of trees in Mexico 1/100th the size of Manhattan's Central Park. So what? It's not like you can have too many butterflies, right?

But the truly baffling part is that monarch butterflies live only for a few months. That means the migration spans generations. Every August, hundreds of millions of butterflies wake up from caterpillardom and know how to find the exact patch of trees that their great-great-grandfathers left six months earlier. This would be like being born knowing exactly how to get to the home your great-great-grandfather was born in, and your mother never told you and you don't even know that he exists or what a great-great grandfather even is because you're a fucking butterfly.

Their most impressive feature, however, is their ability to use their wide-set terror-head as a sort of natural minesweeper, detecting the minutest electrical signal over vast distances or through mud. All sharks have receptors called ampullae of Lorenzini, which actually sounds more like a pasta dish than a super-sensory organ. Hammerheads just have more of them, and they are spread out over that giant head, giving them something similar to an electrical signal detecting radar array on their face.

As a result, hammerheads can detect half a billionth of a volt. For some perspective, when you drive around in your car on a dry day, then get out and zap yourself on the door handle, that's because your body built up about 8,000 to 10,000 volts of static. That is more than a trillion times the voltage needed for a hammerhead to find you, even if you are hiding in an underground bunker at the bottom of the goddamn ocean. Because of this, hammerheads are able to easily find just about anything on the bottom of the ocean that tries to hide from them. Just be glad sharks don't walk around on dry land.

That's right, these beetles developed super-senses for the simple need to bone and lay eggs in burned pine trees. Not only do they have a sense of smell that could rival the silvertip grizzly's, they also have infrared sensors embedded in their chests so advanced that scientists are scrambling to replicate them to use as passive forest-fire detectors. Even DARPA has designs for them.

The beetles, also called black fire beetles, actually flock to forest fires to reproduce, and scientists determined they evolved this way because it's actually safer for the beetles and their offspring. It turns out that most anything that would want to eat the beetles would either flee or be killed by the fire. Also, since the beetles lay their eggs in already dead trees, the trees can't mount their defenses and either drown the kids in acidic sap or grow faster to crush them.

There is a case from 1924 in which a swarm of beetles traveled over 50 miles from the forest to an oil fire in the desert. There is no way they could have known the fire was blazing, since beetle text messages are still a few months off, and there was none of their usual pine fare, yet the entire swarm covered what would be a rough commute for a human to snuggle up to a blazing inferno, all over the promise of some risk-free booty. We might also note that they have a tendency to bite when threatened, and Wikipedia notes that fires cause them to "aggregate to swarms of biting beetles in recently burned areas." If the prevailing winds line up just right, we may actually see a sudden and catastrophic end to the whole Burning Man phenomenon.

And the polarized light? That means that while they are seeing in two spectra that we need thousands of dollars of equipment to see, they can do it with the awesome glare-cutting power of Ray-Bans. There is almost nothing a mantis shrimp can't see, and they would get roughly three times as much enjoyment out of the "Mona Lisa" as we would. But that's hardly where the amazing shit their eyes can do ends. So in addition to seeing the world in a way that can only really be represented with this:

When Cracked promises you superpowers, we deliver that shit. So what could possibly make super-positionable multispectral sunglass-eyes that can probably see ghosts and God himself even more incredible? They have brains designed to clearly interpret all of that information, and they can do it with greater precision than a Blu-ray player. And they can move their eyes, independently, up to 70 degrees in every direction. Remember that alien in Men in Black that looked over its own head? They have more range than that.

So you've probably revised your opinion of Mantis Shrimp Man. You might be picturing him as a secret agent, breaking into a competitor's headquarters, hopscotching his way through an invisible laser alarm system that he can literally see from a mile away, pulling a Blu-ray disc out and reading all the information off it, seeing the approaching security guard sneaking up behind him with eyes that flop over his head just in time and pulling out a gun and shooting him. Well you're close. Only he wouldn't have to pull out a gun, since his arm is a super-powered plasma gun.

Yeah, nature is badass.
