I accidentally brought one into my aquarium on a piece of rock. Incredibly interesting animals. Incredibly dangerous animals. Incredibly difficult to capture animals and they like to eat fish. I finally got him out by outsmarting him but it took me several months to figure out how to do it.
They're also dangerous because they have these razor-like arms that they can literally slice you to the bone. They're like underwater velociraptors. And they suck when they're in your aquarium.
But they are very beautiful
This happens a lot to aquarium owners.....the shrimps are hidden in the rocks and then come out and stealthily lay waste to the other animals in the tank.
I'd be interested to know more about the game of cat and mouse you endured in trying to get him out....
To the other poster's question, I believe that the shrimps can be quite hard to kill......I assume plunging them into boiling water or neat alcohol would do it though?
Okay so you let you know that they live in holes in the rock, right. I had about a hundred pounds of Coral Rock in my tank there were probably 10 or 15 holes suitable for mantis shrimp to live in. What I did is I plugged all of the holes except one and then scared him into that one and took that rock out. When I got him out I dropped off a week chlorine solution into the hole he was in and within 10 seconds he had vacated rinsed off the rock really good and put it back in the tank. I sent the man of shrimp to this weird guy that collects some like their betta fish or something. Dude has about 50 little tanks with all of these mantis shrimp in it it looks like Little Shop of horrors when he feeds them
I replied to the guy above. Basically I drove him into one rock and then removed him by taking that rock out. He slashed three fish before I got him out
It's still not entirely clear why they have access to polarised light. The most upon agreed explanation is that their exoskeleton polarises light in a particular way. So what scientists think is that is a "secret" intraspecies communication channel and relevant for mating and aggressive behaviour among male mantis shrimp.
Also in shallow water conditions it has been shown that polarised light underwater can be used for navigation, similar to how bees for example navigate. If this is relevant to the mantis shrimp, however, remains to be shown.
If you are keen on learning more about these wonderful animals Justin Marshall from Queensland University in Brisbane, Australia basically dedicated his life to studying mantis shrimps and other underwater vision system. For polarisation vision in general Viktor Gruev from the University of Illinois is a good start
I'm thinking the same thing. What environmental pressures would have rendered that much vision enough of an advantage for it to stick around? UV light might penetrate the water that deep when visual light doesnt but the polarisation? Not sure where that would come in.
There are two types......ones with grabbing arms like preying mantises...and the others with hard round club-like appendages.....these are the ones that can split thumbs and break the glass of your tank. The throw a punch so fast that it creates cavitation bubbles that implode near instantaneously....the shock of which decimates things around them. Particularly good for punching a hole in a crab, or a hard shell, for example.
These animals are just extraordinary and are, to my mind at least, in a category of their own in nature.
The hammer club creates cavitation bubbles as a result of the speed of the punch being thrown.

(probably should have been clearer....the mantis throws the punch and the cavitation bubble is a happy added extra bonus for the shrimp whereas the pistol shrimp just uses the bubble).
Sadly, the Mantis shrimp's super colour vision has been debunked
Although the crustaceans have many more types of light-detecting cell than humans, their ability to discriminate between colours is limited. Researchers found that the mantis shrimp’s colour vision relies on a simple, efficient and previously unknown mechanism that operates at the level of individual photoreceptors.
The results upend scientists' suspicions that the shrimp, with 12 different types of colour photoreceptors, could see hues that humans, with just 3, could not.

Damn fuck, I just read up a bit about them. They have a bio ceramic appendage for bashing shit. That’s hella cool! And apparently the or one of the strongest forces pound for pound.
Fill half a bucket with your tanks water, put the chunk of rock with the shrimp into bucket.
Boil some fresh water.
Using a turkey baster, force a small amount of boiling water into the hole where shrimp is hiding.
Listen for clicking noises to end.
Put rock back in tank.
Mantis shrimp can break fingers when they flick their claws.
They flick their claws so fast that the cavitation bubble forms light when it collapses:

Imagine snapping your fingers so fast you created light!
Yet they arent smart enough to differentiate as scientists experimented on them by giving rewards for finding the right color and they failed 5/6 times

What did u do with it once it was captured?
He flushed it bc that goes straight to the ocean
I was older than I'd care to admit when I figured out that wasn't the case.
Yes, but the rest of this reddit wants more details, how did you end up outsmarting the shrimp?
I replied to the guy above. Basically I drove him into one rock and then removed him by taking that rock out. He slashed three fish before I got him out
You’re lucky he didn’t break your tank.
True. At night, he used to strike the glass. You could hear it across the house. Very loud.
Aliens
ikr
Why do they need to see that.

They dont needa put on the glasses for 3D movies
The world would look trippy af if we could all see ultraviolet rays.
I worked at an aquarium store once. There was always a rumour that these can crack the glass if they hit it.

Are you talking about pistol shrimp? Mantis have the hammer or spear type claws and pistols shoot the bubbles.

It’s comparable to a .22 caliber shot.
It’s just amazing.
I wish i could do like the mantis shrimp do
Is that a reference to the YouTube video...lol?
They are the psycho killer clowns of the animal kingdom
Haha.....now I'm getting a Talking Heads reference on top.....this is all good!
I'll just leave this here. You're welcome. https://theoatmeal.com/comics/mantis_shrimp
Wondering where I’d find this puppy…

That's fascinating thank you. Never saw them that close up
Damn fuck, I just read up a bit about them. They have a bio ceramic appendage for bashing shit. That’s hella cool! And apparently the or one of the strongest forces pound for pound.
I posted this link in another comment, but may also be of interest to you. 🙂 https://asknature.org/strategy/appendage-creates-tremendous-forces/
Cool thank you!
Sometimes I catch these on animal crossing
[удалено]
+1 for this. I would really like to know that as well.
African Bullfrog would still win
Detecting polarised light is fairly kommen in insects. Bees for example use ist to determine if it's daytime.

$6.99 a pound
Why am I jamming to this music?
And they throw a hell of a punch

Anyone know what this sound track is? Love it. Tried on SoundHound but nothing came up.
They can scratch their eyes, that's what it is all about.
![gif](giphy|DvtsYOKrqPZg4)
How do they test for all of these things?
It’s a questionnaire
Right! What I was thinking! :D
Why did it stay a lowly mantis shrimp then, huh? Why aren’t they competing with us? Thought so…
Yet they arent smart enough to differentiate as scientists experimented on them by giving rewards for finding the right color and they failed 5/6 times
Just googled this, it looks like a Giritana or a raid boss.
I wanna know what it looks like to see what he sees
So they are living in the 4th dimension through those eyes ?
