How the Giant Water Bug Murders Everything

One of my favorite bug aesthetics has got to be Horrifying Swamp Monster.
Some of the weirdest, creepiest critters alive are sloshing around in a dirty puddle near you.
And none of these guys are more horrifying than the aptly named Giant Water Bug.
An insect so hardcore that it's moved up higher on the food chain than most of the fish,
amphibians, and even reptiles it shares its habitat with.
But how did a bug of all things conquer the world's marshy habitats?
And what makes it such a good predator?
To find out, I've traveled to the Florida Everglades to get my hands on one.
And yes, I mean literally.
Okay, we are currently in water bug habitat.
We're surrounded.
Oh wow, that's a cottonmouth right there.
I almost just stepped on that guy.
I hope you guys can see that.
That could have been horrible.
Water bugs are not the only things out here hunting tonight.
Wow, that was super terrifying.
Yeah, sorry, that rattled me.
That messed up my whole take.
But yes, we are in a flooded marsh home to cottonmouths and many other creatures.
A whole lot of prey items.
So many crawfish, so many frogs, even some tiny turtles I've seen.
So really, this should be a perfect spot to find a hyper predatory water bug
as long as I don't die via cottonmouth first.
As crazy as it sounds,
this juvenile cottonmouth could actually be on the menu of the bug I'm after.
Water bugs are one of the few insects able to attack prey many times larger than themselves.
And aquatic snakes have ended up on their menu on more than one occasion.
Thankfully, I think I'm a little too big to end up as water bug food.
But we're about to find out for certain since hiding in the muck,
I finally found the swamp monster I was after.
All right, guys, here we are with the biggest and baddest bug in America.
Look at the size of that thing.
That, my friends, is the giant water bug.
And man, the way he's just swimming around that tank using those hind legs,
you can really see why this is just like the apex of insects conquering the water.
Nothing else out there is as formidable as this guy.
This guy makes a praying mantis look like it needs to hit the gym more.
Just look at how thick and powerful looking its arms are.
And that is its main weapon.
It cruises around the shallows of these stagnant ponds
and uses those to wrestle its prey, grapple it down,
and finish it off with that tiny proboscis on its face.
That sharp little needle is actually what injects an incredibly formidable toxin
that paralyzes the prey, liquefies it, and enables this guy to suck it right up.
Now, what is something like this going to eat?
The answer, pretty much anything out there.
Sure, you got the usual victims like little dragonfly larva, crawfish,
but these guys will even take out prey bigger than themselves.
Things like water snakes, frogs, even small turtles.
This is a true predator and truly one of the top predators of the world's marshy environments.
This bug is able to take down such monstrous prey because its grip is almost unshakable.
It doesn't matter how big and tough their victims are.
If they can't get the water bug off of them,
there's nothing they can do but count the moments until its venom takes effect.
Other insects like robber flies have made use of this same strategy as well,
but using it in the water is what separates the water bug from everything else,
letting it claw its way higher on this swampy food chain than any other insect.
Look at that, he's actually trying to bust out.
He looks like a prisoner reaching through the bars wanting to grab me.
Let's see just how strong that is.
Wow, yeah, that is firm.
That would do some damage.
You would really love to pull one of my fingers into that death grip right now.
All right, I'm about to do something that really scares me.
I am going to try and grab this thing and pick it up.
Now, I really do not want this to turn into another bite video like the centipede video ended up as,
so I'm going to be very careful.
I'm not going to just let it walk over me.
I'm going to try to pick it up very carefully to where its arms can't reach me,
and hopefully this doesn't go catastrophically wrong.
I don't know if it'd be easier.
Probably be easier if he's not in the water, right?
Just like that.
That wasn't too bad.
All right, wow, he's really holding on to there.
Man, this thing is strong.
I can see how a small crawfish or small animal really would have a hard time shaking its grip.
All right, there we go.
Look at that nightmare fuel.
So weird.
It's such a big bug, but it's really lightweight.
I can see how it's able to cruise through the water super easily.
It really feels like it weighs nothing.
And wow, look at this little snorkel in the back.
It's actually going in and out.
It can actually retract all the way into its body.
That is super weird.
And man, those forearms are wicked, wicked business.
It would love to pull me into its maw and give me a really painful bite.
Now, this might have some of the coolest legs I've seen on any insect.
It's hind legs.
Look at how wide and paddle-shaped they are.
And they do actually have hooks on the back that are really kind of sticking into me right now.
Wow, that like really hooks into my skin.
I almost couldn't pull away.
All right, amazing time with possibly the coolest bug in the world, the giant water bug.
Definitely one of the top bug predators on Earth and one I am really happy I have found here in
Florida.
I hope you guys enjoyed the video, learned a lot.
I hope you stay tuned for other weird and wacky creatures that call this world home.
I will see you guys next time.
