The Insane Biology of: The Mantis Shrimp

[@reme7903]

The fact that their movement is comparable to a bullet is crazy enough but that they do it UNDERWATER is just insane considering that water is much denser than air. If you've ever tired to throw a punch underwater you know how hard water gets when moving fast.

[@BOOGiNS]

Same way ticks jump. It's just a leverage and spring action. Not muscular. Just loading a spring and releasing it.

[@Icetea-2000]

You didn’t understand anything about them. They don’t throw punches, they do not use their muscles like us to move their appendages to strike, they instead hold them back and release the force when they RELAX their body. It is not an input of muscle strength, you cannot compare it to you punching underwater, it’s the exact opposite. Listen to 12:33

keep in mind that if the acceleration of their strikes is faster than a 0.22 caliber bullet, they do it *underwater* , where the medium is denser

[@Melior_Traiano]

And they are a living organism and do not have the help of a powder charge setting the bullet in motion.

[@cosmicbilly]

​@Melior_Traiano the speed of a 22 isn't the same as a 22 bullet. The bullet still carries more energy because of its mass. A lead projectile traveling beyond the speed of sound carries more energy than a shrimp spear. 22 caliber can weigh up to 55 grains. That's much heavier than the shrimp claw. It's still impressive, but I'd much rather get hit by a mantis shrimp than shot with an actual 22 being fired out of a 16+ inch barrel(longer barrel means more velocity)

[@Onihikage]

9:40 I think a clarification might be in order regarding this section about whether the shrimp evolved to cavitate or the cavitation is a happy side effect. A layman may interpret Dr. Patek's response to mean that the shrimp or some mystical mind of evolution knew a future result and evolved towards it. It would be more accurate to say that the cavitation definitely occurred incidentally in an ancestor of the modern shrimp, but it gives such an advantage in almost any scenario that shrimp which could produce cavitation more reliably (and had clubs tough enough to withstand it) had a significant reproductive advantage over those that couldn't because it made them better at killing prey and killing or deterring predators. This selective pressure would have guided the shrimp's evolution down a path to throwing punches that more consistently cause cavitation.

[@NA-nb7fi]

Yeah. It's pretty obvious that the evolutionary process from spear to club would be a slow but steady advancement of speed versus dulling spikes (as you'd need less sharpness to penetrate with more force) with marginal selective advantages but once they reached the cavitation point the advantage erupted and using that was able to open up an entire niche previously untouched by the shrimp (heavily armored prey)

[@you1027]

Personal hunch: the additional wavelengths of polarized light they can see with those super eyes let them visually perceive areas of differing densities in the water with the nuances between how they bend the light. At the speeds they deal with, it probably pays to line up their strikes with pockets of favorable conditions, or avoid injury from striking at bad times where opposing density pockets might apply unwanted deviation from their limbs' safe course. Predators' entire survival hinges on their hunting tools, and at the kinetics these critters deal with it's easy to imagine how misuse of them could see their accidental destruction and subsequent starvation, so avoiding poor shots would be paramount to their survival. The evolutionary investment worthiness of being able to visually pre-empt such instances, would be second only to the weapons themselves. Ever notice when you wear polarized glasses or sunglasses, you can see patterns in translucent layered polycarbons like your car's back window, or the plastic screens at gas pumps? I have a feeling these 'shrimp' get to see the watery world around them in a similar way.

Nifty ! About 30 years ago I had a small aquarium with what the pet store just called fresh water lobsters which got like 4 in long. One time a heard one of them from the other room making a loud clicking sound & it had "bashed"(same or similar behavior) & ate a snail which I always kept a few of too but that was the only time it ever happened, perhaps bc snails were usually at the top on the glass idk. I later seen it attacking a decorative shell making the same noise. They had red ones & blue ones. It was a blue one that I witnessed the bashing with btw. At one point I had both a red & blue & they mated, where the red one was the female & it hatched dozens of purplish ones. At 1st I didn't know they ate their offspring but I managed to move 3 to a seperate tank where only 1 managed to survive for maybe 2 years, which was the longest lifetime throughout the entire adventure.

"If the speed of their clubs at 31 m/sec isn't impressive enough, the acceleration of those clubs rivals the acceleration of a bullet from a gun." WRONG: Firearm muzzle velocities range from 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets. Modern rifles with high-velocity cartridges can have muzzle velocities of more than 1,200 m/s (3,900 ft/s). So, maybe she's referring to weaponry from 1700s, but doubtful. No moden firearm post 1930+ is slower than her claim of 1000 ft/s velocity.

she was comparing acceleration, not velocity! as in, the mantis shrimp's claw goes from zero to a hundred faster than a bullet does when exiting a barrel!

This gives me an idea for a sci-fi species... The cavitation and extreme forces make me wonder if it could solve the issue of aquatic species learning to manipulate metals. I'm not super familiar with the concept but the theory as I've heard is that technology and tools would be harder to develop without fire. Some strong enough battering arms combined with a set of tool handling arms evolved from their next pair of limbs down and we've got some industrious shrimp!

An attempt at visualizing what those kinda polarized lights would look like, or what it would be like to interpret them. Would've been nice.

[@HuyV]

She kind of said it in a way that's easy to misunderstand. Humans CAN absolutely see polarized light or else your phone screen would look black, since pretty much all our displays emit polarized light. We just can't distinguish between polarizations. What the shrimp likely has is different polarization filters over different receptors, like when you put on those 3D glasses, your eyes effectively become able to distinguish between two different polarizations by one eye getting a filter that only passes through one certain polarization. Those shrimps just have those filters already built into the eyes. Another misconception is the circular polarization thing. It's not actually anything that's rotating. The effective field vector seems to be rotating, but what that really means is that the horizontal and vertical field components just have a phase shift of pi/2. In the end there is no way to tell how something like that would look, because how a color looks is completely personal. The way I perceive yellow might be different than the way you do. We all just agree on names we give to a certain wavelength and that certain objects emit those wavelengths. That's why it's impossible to tell a blind person what blue looks like. All we can do is use comparisons to objects that are also blue. I hope that makes sense.

I know I’m the minority here, but good lord it’s astonishing how people think simple chance due to wholly random variables has the ability to somehow create a creature as amazing as this. How is natural selection able to select something that doesn’t even exist? The principle of natural selection is to select genes and traits already coded within dna. It reminds me of the analogy that if you put a whole bunch of chimps in a room and give them typewriters, they’ll eventually create Shakespeare. We all know they wouldn’t, and the same principle applies here. I believe in natural selection, but not as a means of evolution. I believe there was a base level mantis shrimp or similar shrimp creature and natural selection created the species we see today. But nothing beyond that. The

[@nightmike7655]

I believe you have a little misconception about the gene selection. You are not taking account of natural variability within populations and gene mutations. Your chimp analogy is somewhat incorrect in the sense that you are not considering the variability over time in aleles frequencies over their population. If you have a population of primates, and given millions of years, their descendants will eventually become homo sapiens and one of them will be Shakespeare. Correct me if I'm wrong, but I think you are dismissing the fact that the children do not share the same dna as their parents, so variability is introduced in each generation, and those favorable genes will propagate, either by recombination of parents or by mutations. This is how we eventually got watermelons from wild berries, because the selective pressure was artificially introduces by us.

@@nightmike7655 but how are fully formed populations with intact genetic material supposed to propagate? And you’re looking at history through the lens of universalism. Assuming that conditions now are pretty much the same they’ve always been. And I’m not sure how gene mutations are supposed to create good ends. Since despite what we see in Hollywood, mutation is generally always a bad thing. And I do have a question, I know when I was a kid, I thought it was weird how we were supposed to evolve from apes, yet apes are still around. Is the evolutionary explanation that only some apes evolved into homosapiens and some stayed as apes? Or that other creatures evolved into apes whilst the apes evolved into humans? And in terms of your parent dna explanation and the watermelon thing. I know that their is much gene variability within a particular species, but the species itself still relies on its base set of genetic information. That generally speaking, a creature would start off with the base set of genes and those genes are propagated and naturally selected in and out, but never creating more. Mutations are the only explanation I am aware of that can account for the creation of new genes. But as I said before mutations generally aren’t a good thing. It’s similar to messing with the code in a computer randomly, it may hurt it, it might do nothing, but it would hardly ever help it work. And these derivations from the original code tend to break it down regardless of whether or not it hurts or does nothing in the short term. And can you explain gene drift I think it’s called?

haven't seen your purty eyes in a while, Steph! Awe inspiring video as always

My mother used to run a Chinese restaurant that displayed live sea food and mantis shrimps for food (the mantis clawed ones). She’d tell me one time she tried to grab one and it clawed her so bad it wouldn’t stop bleeding for the day. Bloody delicious though.

well if they can see so many wavelengths that we can't see, then the difference between shades of purple for example is probably super insignificant to them, from their perspective of seeing so much MORE than that. to us its like "hmm i prefer the slightly lighter shade" to them their seeing so much more that the difference between two shades of purple just isn't important to them. they only see that it is purple because that's all it really is to them. the shade isn't a significant difference.

Thank you so much for this. The videos you do are super high quality and are just amazing. I've actually been waiting for this one.

[@MineStrongth]

Praise God! I love these videos.
