For just about every superhero or villain who’s graced the pages of a comic book or
cineplex screen, nature has an answer. The animal world is full of inspiration when it
comes to awesome abilities and many of nature’s super powers put their comic counterparts
to shame. So strap on your utility belts, and behold, the Avengers of evolution.
Chitons are a family of pretty ancient looking mollusks that haven’t changed much in
about the past half billion years. Course, if you had 17 regenerating rose iron magnetite
covered teeth that could grind away algae-crusted rocks, why would you change? Every budding
young scientists have found themselves chasing lizards in the backyard at some point, and
like most of us, you probably just ended up with a wriggling tail and no lizard. Not only
can many lizards and geckos regrow their posterior, but the mythical-looking axolotl salamander
can regenerate entire limbs.
Speaking of Wolverine, this Hairy Frog can break its bones and shove them out its fingers
to make claws. That has got to be the most painful self-defense mechanism in the animal
kingdom, but at least your enemies will know you’re not messing around because you will
stab them with your own bones. Sometimes the best way to survive in nature
is without being seen at all. The cuttlefish is a master mimic, can not only take the shape
of things around it, but it can camouflage itself with even the most complicated furniture
patterns. Some sharks have special luminescent organs on their bellies. They give off a blue
light that matches the color of the sunlight above them, so the predator swimming below,
they might as well be invisible. In the darkest depths of the sea, all the red light has been
filtered out by the water above, so red creatures like this jellyfish reflect 0 lights. Down
there, they’re as good as black. Pit vipers like the rattlesnake might as well have 4
eyes, two regular and rather scary ones close to specialized organs just in front that let
them see a 3D thermal view of the world. If you’re warm, you’re toast.
[scream] This next one is a truly super power. Meet
the Lesser Water Boatman. It’s a tiny insect that holds the title of the loudest animal
on Earth by size. Just don’t tell him he’s lesser. He makes a call as loud as a power
tool despite being only two millimeters long. How? By rubbing his penis along his abdomen.
Elephants are able to speak without sound. Instead they use something called infrasound,
emitting low-frequency waves far below the range of the human ear, that they can travel
hundreds of kilometers through the ground. It’s not quite telepathy, but it might be
the closest thing that we’ve found Without using Google Maps, or GPS, just their
mere fishy brains, adult salmon are able to swim thousands of miles across oceans and
up rushing rapids, to return to the same mountain streams they were hatched in years before.
They can actually be guided home by Earth’s magnetic field. Exactly how is still a mystery,
but they’re imprinted from birth with a compass bearing pointed right back home.
Tardigrades. Those adorable, indestructible, tiny teddy bears of the animal world can survive
the complete vacuum in deadly radiation of space, go without eating for as long as a
decade, and just shrug off temperatures ranging from minus 200 to 150 degrees Celsius. They
might just be tough enough to set up the first colony on Mars.
Deinococcus Radiodurans. It’s a bacterium that can withstand a radiation dose two thousand
times higher than what would kill a human. It’s thanks to the antioxidant properties
of the element manganese. You think doing a little bit of yoga makes
you flexible? A sea cucumber’s body is made of a special kind of collagen, that it can
essentially liquefy on command in order to squeeze itself into tight spaces.
Hyenas have stomachs of steel, which makes sense for something that eats rotting carcasses
like they’re made of ice cream sundaes. Their stomach acid’s so strong that they
can eat anthrax infected corpses and laugh about it when they’re done.
Now, the dragon millipede is a curiously pink insect, and in fact it’s one of the only
pink creatures on Earth. Now nature, that’s usually a sign that says, “Back off!”
and for good reason. See, this toxic beauty sprays clouds of almond smelling cyanide gas,
but if you’re close enough to take a whiff, it’s probably too late.
You’d be forgiven for thinking the platypus was a ridiculous prank played on biologists
by Mother Nature. In fact, the first platypus skins were discarded as fakes because researchers
thought they’re made from duckbills sewn on the beaver hides. Now these monotremes
can hunt using electro-reception. No eyes, no ears needed. You can try to run, but that’s
just the nerve impulse there waiting for. Electric eels are full of cells called electrocites
that build up charge like a living battery. When they choose to discharge it, they can
release 500 volts of electric shock. Now that’s more than enough to kill a human and certainly
enough to make your heart skip a beat. Dung beetles are known to push over 1,100
times their weight in poop. That’s like an adult human tugging around a dozen buses.
Not- not only are they super strong, they’re master astronomers, navigating their stinky
cargo by the light of the Milky Way. A gecko’s foot pads are covered in microscopic
hairs, almost as small as the wavelength of light.
They can stick to surfaces without suction, or liquid. They’re held in place by Van
Der Waals interactions that take place between individual atoms in their feet and a wall
or a window. Wood frogs can hibernate by burying themselves
underground near the frost line. Now while sharp needles of ice would rip ourselves to
shreds and leave us as dead as a freezer burn hamburger patty, these frogs can cryo-preserve
their bodies by filling their cells with glucose. It’s like nature’s antifreeze.
Some people call turritopsis the “immortal jellyfish.” While it’s probably not immortal
on a strict sense, it can revert fully differentiated adult cells back into the form of an embryo,
then send them off to continue a new life. With the aid of gravity, a peregrine falcon
can hit nearly 250 miles an hour in an attack dive, and the sleek black marlin has been
clocked at 80 miles per hour, but as far as land animals go,
no one can touch the cheetah, which can run at sixty miles per hour for a full minute,
and at full speed, actually spends more time in the air than on the ground.
A flea has the ability to leap two hundred times its body length, in a single bound.
And that’s thanks to special structures in their hind legs that are shaped like coiled
springs. That’s equivalent to six foot three me jumping a quarter-mile in one hop!
The bombardier beetle can shoot a stream of caustic chemicals out its backside, thanks
to an internal chemical reaction and some careful aim. And that nearly boiling jet is
hot enough to kill or blind small creatures. It reminds me of Cyclops from X-Men... only
backwards. In addition to an expanded vision range that
can even sense polarized lights, the mantis shrimp can punch with as much force as a rifle
bullet, hitting speeds of 50 miles per hour with their club-like arms. Before you even
know he’s swinging, you’re dead. Pistol shrimp claws can snap with such immense
force that they shoot a death bubble at their prey at 60 miles per hour. That bubble is
as loud as a supersonic jet, and because of the phenomenon called cavitation, it’s almost
as hot as the surface of the sun. I guess they can kill and cook their dinner at the
same time! As you can see, nature’s full of some pretty
super powers, and they’re all real. Reading stories of far-off worlds, leotard-wearing
heroes and evil villains is fun, but it’s nice to know that some of the best stories
have already been written by evolution. Did I forget any cool animals? Well, let me
know in the comments! Stay curious, and we’ll see you next time.
