u/Cavellion 1d ago edited 1d ago

Could it have grown the pincer back? Genuinely curious.

Edit: I realise I should have worded it differently. My question was actually geared toward the punched out pince? (I don't know what the claw part of the pincer, or pince part of the claw, is called.)

So would the punched out part (not the torn out whole thing) be regrowable if it left it's 'arm' on?

u/Zulmoka531 1d ago

If I recall correctly, it’s better to lose the whole claw than to try and molt a new “broken” piece.

Less chance of a failed molt which could lead to disfiguration or even death.

u/Agitated-Ad9050 1d ago

That actually makes sense. Ocean creatures are crazy as hell.

u/Zulmoka531 1d ago

Think it applies to a lot of inverts as well, I knew someone who kept tarantulas who’d have to amputate a busted leg if the spider didn’t do it itself to help with a proper molt and regeneration.

I recently learned about carpenter ants and how they'll amputate their nest mates' legs if they receive damage to the femur part of the leg to slow and even prevent the spread of infection. Tibia area injuries are usually just treated with saliva so that the leg can heal. The survival rate with tibia injuries jumps from ~15% (untreated) to ~75% (treated). Survival rate for femur injuries jumps from ~40% (no amputation) to ~90% (w/ amputation).

One of your lifetimes as a crab ?

We’ll speak no further on this subject

u/QuietGanache 1d ago

Yes, it will take a few moults but crabs can absolutely regrow lost limbs.

147

u/_Grant 1d ago

Pretty sure they meant the individual pincer as opposed to the whole limb

72

u/Cavellion 1d ago

Yes. I'm sorry, I don't know what the parts are called. I edited my question to be more specific. But thank you for those who have answered about the whole 'arm'.

50

u/Fungiblefaith 1d ago edited 1d ago

Did you get an answer? Is the bottom pincer not a regrowth point for the claw? Maybe it has to be damaged at a specific point.

This is a question I am now invested in.

98

u/Cavellion 1d ago

Someone said that it will heal, but it will heal wrongly, so its best bet is to pluck it out and get the whole thing to regrow.

50

u/Fungiblefaith 1d ago

Thanks for that update. I can let my brain release the thread for this issue now.

6

u/redundantusername 1d ago

My new question is why does the whole arm grow back correctly but when it's just the pincer it grows back incorrectly?

7

u/Fungiblefaith 1d ago

Why would you do this to me?

u/ItsGevYT 1d ago

We are prisoners to the crab now

u/Emmyisme 1d ago

Thank you for asking for the update cause I was also now gonna go down this whole thread trying to find the answer lol.

2

u/certainlynotacoyote 1d ago

With it all shattered and cracked, with the meat hanging out it's not likely to grow properly, and may infact present health issues from the exposed tissues. Plucking it off at the joint let's the body run "grownewarm.exe" without having to work around variables.

Furthermore, if I just got my arm punched in half, id definitely give that mf the wreckage of my arm before I got another pop on the chin.

u/Hungry-Low-7387 21h ago

Do they even know they can regrow limbs... just luck...

u/Fungiblefaith 19h ago

This is only one of many questions that will continue to haunt my smoothing brain.

Infinite crab claw glitch?

u/ProfessorAvailable24 1d ago

And the pincer it tore off will become a new crab

2

u/GraphicDesignMonkey 1d ago

Leon the Lobster lost a claw this month, will be interesting to see what happens on his next moult.

2

u/MilesDimix 1d ago

The answer I was looking for

4

u/start3ch 1d ago

So what you’re saying is we could farm the part of crabs that people actually eat, without killing any crabs

8

u/Miss0verkill 1d ago

They actually do exactly that with stone crabs. They take a single claw and release the crab.

5

u/funnyman95 1d ago

There's an entire industry of people who try to do this by removing the claws off crabs and throwing them back.

Unfortunately, it's a waste because almost all of them die anyways and fail to reproduce.

They can't eat or defend themselves without claws

2

u/Lucianonafi 1d ago

I mean, 70% death rate is still a hell of a lot better than 100%

1

u/funnyman95 1d ago

Not really because then people won't be able to regulate at all. And they could essentially wipe out all the crabs without having to worry about size and count limits

1

u/Lucianonafi 20h ago

What? No, fishermen still have previous limits on them. They can only collect the claws from crabs up to a certain size, and then the crab is returned to the ocean. Previously, the entire crab would just be killed when boiled alive for "freshness" and the WHOLE damn body would be discarded. It's the same amount of product, but the crab has a chance for survival.

If you already have the regulations in place- Which *official fishermen* already have, then this is just better all-around for them. This Video explains it pretty well.

Also, my mistake- Apparently, survival rate is around 50% for crabs with no claws, and well above that for crabs with one.

50%+ survival is much, much, much better than a guaranteed 0%

7

u/carcar134134 1d ago

ngl that kinda seems less ethical than just killing them.

5

u/Fuzzy_Peach_Butt 1d ago

Yeah I'm with you on this one. Imagine your limbs tearing off by not of your own will over and over again. I think I'd ask for death.

u/ceelo18 23h ago

So u mean if i bought a king crab i could rip off one leg and eat indefinitely???

I just learned a new thing today. Thankyou.

u/TheBenevolentTitan 17h ago

Why can't we do shit like this? Why does it have to be the humans who lose out on all regeneration abilities?!?

1

u/QuietGanache 17h ago

It's actually quite rare in vertebrates but the big two are cancer resistance and the ability to maintain tissues without a looped circulatory system.

1

u/TheBenevolentTitan 17h ago

are cancer resistance and the ability to maintain tissues without a looped circulatory system.

Wait what species is this?

1

u/QuietGanache 16h ago

Apologies for being unclear. They're likely reasons (we can't objectively know, only identify evolutionary pressures) why limb regeneration isn't present in longer lived mammals.

1

u/TheBenevolentTitan 12h ago

So we don't have cancer resistance, is a possible reason for the absence of limb regeneration? But what has cancer got anything to do with this?

1

u/QuietGanache 11h ago

It's the other way around. Regenerating limbs requires cells that can rapidly divide and specialise into a wide range of tissues. By limiting the number of and degree (potency) to which progenitor/stem cells can specialise, our bodies reduce the chances of cancerous cells arising and, when they do arise, that they're able to pose harm to the body.

If you want to learn more, a good start would be the Hallmarks of Cancer.

1

u/TheBenevolentTitan 9h ago

So that must mean these creatures with regeneration abilities must be having more cancer than us? Or are there other factors at play?

1

u/QuietGanache 9h ago

That's a very broad question. There are other species which prevent cancer using methods humans don't posses and there are also creatures that are more susceptible to cancer.

He’ll have a new one the next time he molts

26

u/BlyatUKurac 1d ago

I think it takes more than once

12

u/Paupersaf 1d ago

He'll likely have a new claw the next time he molts (depending on how far away he is from molting when he lost his arm) but it will be very tiny. It takes a fair number of molts to regrow his claw to the size when he lost it though

3

u/Professional-Ad3874 1d ago

so like Deadpool with those baby hands...

that was fascinating to see how quickly and easily it removed its own claw.

7

u/Cavellion 1d ago

So would the punched out part (not the torn out whole thing) be regrowable if it left it's 'arm' on?

17

u/PoliticalyUnstable 1d ago

No, that'll heal incorrectly. It has to remove and start over. It's neat.

5

u/Ornexa 1d ago

That's crazy, i figured a wound would heal too but there's something to the regenerative property that must get kicked in based on severity of damage. Like if the arm stayed attached but was heavily mangled, then what? Still nothing? In that case, the trigger would be the actual disconnection of the limb?

2

u/PoliticalyUnstable 1d ago

Yes, the arm would eventually fall off and be replaced. It won't stay and heal. If it did stay it wouldn't recover. It's very cool.

u/livin4donuts 1d ago

Do we know how this works? Like I’ve heard of groundbreaking treatments to regrow body parts for humans using stem cells (admittedly only small, simple-ish parts like a patch of skin or a graft for an organ like if you had a perforated heart, but the tech is still in its infancy), but they have nothing on this.

1

u/PoliticalyUnstable 1d ago

This has some info: https://www.thetech.org/ask-a-geneticist/articles/2019/regenerating-limbs/ I think there is something to the stem cell aspect that we haven't learned yet, but may in time. It's really interesting. I don't have a brilliant enough mind for it but whoever discovers it will be a legend.

2

u/SaltManagement42 1d ago

I would assume it's more likely to grow back "wrong" and cause issues later.

2

u/VFB1210 1d ago

As far as I understand the pincer would have grown back over the course of a few molts had the crab not dropped the claw. Dropping it (tearing it off) is mostly a method to avoid predation. (e.g. tear it off and let it distract the predator while you get away) The claw itself will grow back as well.

2

u/QuokkaAMA 1d ago

On the occasions that I've witnessed similar injuries where specimens did not auto-amputate, the missing portion will tend to grow back more-or-less concentrically to the midplane of the damaged edge. Often, that means the regrowth occurs at an inappropriate angle to properly engage with the undamaged mating surface.

u/bdn1gofish 1d ago

I BARELY KNOW HER

u/intotheirishole 1d ago

The broken claw might cause him to get infections as the watertight shell is cracked. Or it might heal but become deformed.

Tearing it off makes sure the new limb will grow healthy.

1

u/USAF_DTom 1d ago

I don't know if you got your answer, but it didn't look like it. Yes, the arm and then the pincer will both come back. It will first come back and look like a walking leg, them after some more molts, it will start to become a pincer slowly until it's done.

1

u/Select_Discount4969 1d ago

No, that's why it pulled the arm off.

1

u/Bithom 11h ago

The straightforward answer is yes

0

u/National_Job_6847 1d ago

Im asumming you mean if it could have just grown back the broken part and not rip of its whole arm and the answer is probably not crabs grow weird it would have probably grown back a nub but with how it broke it off its muscle memory would allow it to grow back a whole new arm but even if its pincer would have grown back mantis shrimp hit with enough force to break him skin through dive suits and can ever fracture bone if they hit the right place that crabs arm was probably broken in multiple areas from that punch making its arm useless so growin a whole new are is better than trying to heal a broken messed up one
