So I did a little bit of my own research, and checked with a few gun owner people I know, and a .22 caliber bullet only hits with about 900-1200 newtons of force with bigger more powerful guns, and usually less with smaller guns? Which would mean that if the 1500 newton paper you cited is accurate then they can in fact hit with more force than a small bullet?

Good example of how force isnt really indicative of damage, a bonk with a stick on something hard can put even more force and Id not exactly rather take a bullet... For impact, you wanna look at things like shape, energy, momentum and how they relate to each other to get the roughest idea that is actually useful...

I used to catch smasher mantis shrimp at my local beach as a kid to keep them in my aquarium. I used to pick them up with my bare hands (~10 cm Gonodactylus). No broken bones. Felt like being snapped with a strong rubber band. They were incredibly intelligent creatures based on observing them in the tank over a year.

Back in my grad student days (ca. 1970), I had a small salt-water aquarium in my office, containing among other things a small mantis shrimp. He was very well behaved and a lot of fun to watch. Crustaceans are often characterized by having biramous (two-branched) appendages, but many stomatopod appendages are triramous (three-branched), which is unique in the crustaceans. And don't get me started on their eyes! They have really marched to their own drummer.

thank you sooooo much for pointing out the difference between speed and force with the bullet/raptorial appendage analogy! It's so annoying especially in videos where you see a tiny crab, which you probably could crush with your fingers, surviving multiple hits of the appendages supposedly moving with "the force of a bullet."

@@barnabyandanthonysofficial1497 I'm just thinking in general terms, material strength isn't a two-dimensional scale. Something can be highly resistant to one form of damage and highly vulnerable to others. Bulletproof materials can often be broken with a hammer, or even with a really hard kick, since they are specifically built for *bullet* resistance, not hammer or kick resistance. You have a great day too! :)

Ex fisherman here, sometimes get them in the Atlantic, we called them "Finger Splitters" They were more likely to split your skin than break a finger, but fisherman also wear gloves but they didnt help. pick em up behind the head....... The punch works a bit like a cricket leg or flea limb in that they're "cocked" at rest so just grabbing the head doeasn't stop it getting you as you might imagine..... Deffo don't borrow money off them. 😂

You didn't say why cavitation bubbles are so destructive, which is the best part. Cavitation bubbles are not like air bubbles, witch are fill of gas. These bubbles are held open by the gas pressure and the rapidly float up to the surface, betting bigger as they rise because the water pressure gets lower. Cavitation bubble form when a solid object, like a boat propeller or mantis shrimp claw moves through the water so fast, the water doesn't have time to fill in the space left behind. Cavitation bubbles are filled with vacuumed, and so they literally suck the water back as they collapse at extremely high speed. If this high speed water strikes something solid it hit's with enough force to destroy metal..

I guess the smasher shrimp punch possibly could break finger bones since they are covered by fairly thin skin and not much more... At least it would almost certainly give a nasty bruise; so I'll keep my hands far away. But I would assume the cavitation effect is more dangerous to exoskeletons and (other hard and brittle stuff) and not as effective against thick soft tissue.

On the punch force-bullet thing, a mantis shrimp can put out around 100 joules of kinetic energy. .22 Short cartridges put out around the same kinetic energy. That cartridge is largely used in pest control because of its low energy minimizing the chance of damaging something besides the pest. It's used in a lot of target competitions for similar reasons, you don't need as big as berm behind your targets and the low noise and recoil is better for the shooter.

From what I gathered, sclerite 1 is attached to the ventral medial edge of of the merus wall, so when the attached medial flexor contracts, a lip on the merus wall is made with a small indent. Then when the lateral flexor (further from the midline of the shrimp than the medial flexor) contracts, the larger sclerite 2 is cocked back over the ridge in the posterior portion of the ventral medial created by sclerite 1. Then, from what I gathered, the medial and lateral extensors contract until the force applied to sclerite 2 by the flexors is outdone by the extensors, at which point it moves over the ridge, creating a largely sudden motion with high acceleration. Also, confusion on the diagrams comes from the fact that the superior portion of the merus is hidden in the left part of fig2 (so we can see the sclerites and flexors) but isn’t hidden on the right part of fig2

The amount of force required to break a human hand bone on average was found to be 1485N so its pretty close to the max of the mantis shrimp, but the 1500N max was presumably underwater, and while a mantis shrimp unleashing this force out of water would be much stronger, it would most likely be very injured as the extra forces would probably rip its arms on the inside.

4:18 before you explain any further I'll try and recall physics 101. Force = mass * acceleration So if you've got a mantis shrimp claw that weighs as much as a bullet, then that could be true... But I'm gonna go out on a limb and estimate that a bullet of LEAD would probably be more dense than a Mantis Shrimpy

According to that report the optimum barrel length for velocity was 18" in low velocity and 20" in high velocity ammo. Many . 22 LR cartridges use bullets lighter than the standard 40 gr (2.6 g), fired at even higher velocities. Hyper-velocity bullets usually weigh around 30 to 32 gr (1.9 to 2.1 g) and can have a muzzle velocity of 1,400 to 1,800 feet per second (430 to 550 m/s). For the minimum values, we have: Mass of bullet: 1.9 g = 0.0019 kg Velocity of bullet: 430 m/s Using the formula F = m*a, we can calculate the acceleration of the bullet as: a = (v^2 - v0^2)/(2s) = (430^2 - 0^2)/(20.508) = 19984.25 m/s^2 Then, the force can be calculated as: F = m*a = 0.0019 * 19984.25 = 37.97 N For the maximum values, we have: Mass of bullet: 2.1 g = 0.0021 kg Velocity of bullet: 550 m/s Using the same formulas as above, we can calculate the acceleration and force as: a = (v^2 - v0^2)/(2s) = (550^2 - 0^2)/(20.508) = 30027.56 m/s^2 F = m*a = 0.0021 * 30027.56 = 63.06 N Therefore, the range of forces for the .22 LR cartridges with hyper-velocity bullets is approximately 38 N to 63 N.

I love your videos!! You are so funny and I learn a lot too! I love it when you go off on a tangent! 🤣😂🤣😂The spear mantis’ are super cool! there’s footage on here on KZfaq of how they catch fish in the wild. I have a reef tank… been in the hobby for years. I used to have nightmares of having a mantis in my reef tank, for I am terrified of them too. Although very interesting, they are very scary. And those eyes! Did you know they have the most advanced eyesight in the animal kingdom? For some reason, they can also see ultraviolet light.
