What’s Plastic-Looking Substance Inside a Crab Leg? (Not Bone)

[@vphhotos]

the crab innards is so interesting also wondering how they breathe through gills with complete exoskeleton outside

[@Newtype_96]

crabs have special adaptations to keep their gills moist and functional. They have articulating plates that can close to prevent dry air from entering and drying out the gills. Additionally, crabs can draw water over their gills using a thin appendage called the scaphognathite, which is located near their claws. This mechanism ensures that their gills remain moist and capable of extracting oxygen from the water. in the end it's a membrane that lets water in.

[@tedarcher9120]

​@@Newtype_96how do they breathe on land though?

[@greghelton4668]

They’ll die if the gill dry out.

[@EphemeralPseudonym]

​@@tedarcher9120keeping water on the gills until they go back

[@PcMeowster]

Crabs contain Iron Maiden, Metallica, Black Sabbath and Megadeth? Every day is a school day.

[@toryumau6798]

… The most METAL of creatures. Approach one carelessly, and it immediately gives you the double horns. >)B^} ,\m/

[@kawaiihypernova]

I'm in the medical field and learning about how crabs have some similar structures to humans is so fascinating to me. Thank you for sharing! This was a cool video.

[@Reddotzebra]

Their immune system is also extremely interesting, instead of having separate cells for wound repair and the phagocytosis of pathogens, they have one kind of cell that does both. So it's like a platelet and a leukocyte in one package.

[@TheFaceless87]

I love these random fun facts. You just learn something new everyday.

[@VictoriaVoltia]

Yeah, although does the crab okay? Its seems losing one of its leg.

[@bdbgh]

I didn't know about heavy metals concentrated in the crabs guts, you learn something new everyday

[@marcusbullock630]

this is literally all animals not just crabs

[@polarspirit]

Squid also has a backbone that looks like plastic

[@porko882]

I think its their tendons, in you pull on the ends of them you the pincers will open and close. Discovered this when they used to have snowcrab legs at the Mandarin buffets.

[@HoldMy1911]

Are you telling me, that wherever you live, chicken is more expensive than scallops?

[@kun]

SEBASTIAN IS BACK OMG

[@7Seven-on1yi]

Sometimes when I get bored I eat the claw and pull the like plastic thingy and it basically retracts the claw like a scissor

[@ghivora9344]

What a cute catter...

[@arcaneomega1]

Do a squid inside the head, please, it's so weird

[@shadowmystery5613]

After having seen what crabs look from the inside I don't want to eat any... EVER 😂

[@triadwarfare]

Better start going vegan as it won't go any better from here.

[@ElementalAer]

Wait when you see how a fish look. Hell, even a fresh killed chicken.

[@Bleilock1]

​@@ElementalAertbh i dont find any of it gross, its nature

[@ElementalAer]

@@Bleilock1 Me neither, it's even somewhat educative to kill and clean food.

[@RamlyJer]

I see.. I thought that was a crab's bones lol 😆 I miss Sebastian good to see em again 👍

[@intorsusvolo7834]

I like the sound effects :3

[@Rockhopperforlife]

:3 spotted

[@SamSonicVideos]

Turn up for the fish, stay for Sebastian. 😸

[@MellowMika-rv3gv]

Yay new video!! Ps.. thanks for teaching me such interesting things!❤

[@WatDaFakMan]

is it me or he speaks really slow? i had to make it x2 lol (context, i am chilean, we speak fast) maybe is just my perception of his voice, but i need to know if anyone else thinks alike. also, cool video, the information was clear and nicely explained

[@hypertion]

I know this from childhood.. family likes fish and i saw the discarded claw and played with it. With mom being in medical and me just being the kind of kid explore any kind of non-school required knowledge i knew it was a tendon and would control the claw if i moved it. So ya 10 or so old me knew the answer to this video before clicking. Current near 40 me is getting a blast from the past nostalgia trip from the vid. 😊

[@battlesheep2552]

You know, i wondered how their muscles could still work to make them move after they've molted and are all floppy, figures they'd still have something solid like tendons to help them move.

[@mdanov]

If you think about it, domestic cats are closely related to african wildcats that originate from the area surrounding the sahara desert. Although some of them eat seafood, they never ate it in the wild during their evolution.

[@ElysetheEevee]

Kitties may love seafood in general, but the heavy metals in them afflict cats far more than humans. Giving your cat seafood isnt advised, especially things like tuna. Cooked chicken (not raw), eggs, and turkey is pretty safe for cats. If you want to make homemade cat food (which I had to do for one of my cats way back when), make sure to look up what foods are good for daily consumption. Generally red meats are only rare treats and shouldn't be given to cats often. If you can't get powdered taurine supplement to mix into their food for the proper levels in addition to meats, the ground egg shells can provide a temporary source. These are just some random cat food tips I learned ages ago having to make food for a kitty that couldn't eat any store-bought foods growing up. He eventually got over his intolerance when he matured, thankfully. Watching the kitty eating seafood just reminded me, that's all, lol.

[@alexander1055]

Cats are carnivores and will thrive on raw red meats. Raw poultry is perfectly fine too.

[@marcusbullock630]

thats incorrect about tuna. its not the metals but the high amount of omega 3 fatty acids which causes fatty liver. never feed cats oily foods of any kind.

[@kamikeserpentail3778]

Fish is one of the highest allergens for cats. It can also contribute towards urinary tract infections, especially in neutered male cats. I'll occasionally give mine a tiny piece of salmon if she seems interested, when I make some for myself, but not much and definitely not regularly.

[@TheSwarm666X]

in the end i am just glad to see Sebastian again.

[@kamikeserpentail3778]

Learned more about biology eating a crab leg in a restaurant than I did dissecting a worm in biology class in high school.

[@swagloading5662]

"open up a crab" my hungry ass mhm yummy yummy

[@chrisinhotwater9896]

I know what that stuff is. It's the stuff that holds the really good tasting meat together.

[@vigilwrath3650]

Now do with squid i always eat squid but never know what organ they had. Maybe do video about catfish

[@oscarp4328]

2:37 which is why I don’t eat shellfish.

[@DefileOdds]

Anyone who thinks crabs have inside bones.... has never had crab lol.

[@humanbass]

The Japanese living super long proves that heavy metal in seafood is overblown

[@lmars]

I clicked because I know, and everyone should know that this is a tendon that allows the crab 🦀 to control movement in their legs just like humans and other animals have. What else will they add?

[@okamijubei]

Cartilage, just to keep their joints intact

[@lagoz9985]

Sebastian

[@Chiongster101]

I played with this as a kid

[@vincentwu2848]

Damn raw crab meat looks so unappetizing

[@danlaurel311]

Hey neat, now i know what is that for, always had that question in my mind as a kid playing with a crabs arm or pincers, now i know, thanks for this

[@ConcreteBombDeep]

How dare you dissect that innocent crab while it's still alive. You like like Anthony Hopkins where he disects that guys brain at the dinner table.

[@ThaT_RarE_ShrubB]

Oh no, what happened to mr krabs

[@kitsunetengoku1467]

Well, if it isn’t a bone then it’s a plastic looking substance. Nice

[@rynieryarom4277]

Do they molt the tendons?

[@GrimSoulBanisher]

I listen to Anthrax, Lamb of God, and so many others every day. Have I caused irreversible damage to my innards?

[@para4436]

Do they poop? Edit: the ones in the tank looked so cute

[@manobit]

Weird but cute Sebastian. 🤣

[@白雪猫-f1t]

This video makes me hungry

[@marcusbullock630]

all crustacea and also chelicerata have and endo AND exo skeleton. while its not bone, it is an endoskeleton nonetheless. spiders and scorpions have it too.

[@robotnikkkk001]

...BASICALLY THEIR TENDONS,SORT OF....RIGHT? .....

[@ZnigcvnYT]

I see that in crab too

[@DimasFajar-ns4vb]

tasmania crab sir its big

[@Dellvmnyam]

Not surprisingly Sebastian likes gourmet meat ^_^

[@realdragon]

What microplastics do to nature

[@bernadettavarley]

YEEEAAHHH!!!! SABASTIAN!

[@yurianasy]

When I see it, thats plastic 🤢 After know it 😂

[@EmoZhaeNan]

Fishermen are devastating the seas so try as much as possible not to eat sea animals

[@EdvinPerez-kc7dg]

You feel like you make me feel like you’re teaching me more than school teaches me😂

[@joechua8426]

Chonky Sebby

[@Sciguy95]

I dont know if i can trust what hes saying. The science in this video seems a bit "fishy" to me.

[@deadlylive_gaming7154]

😮

[@user-tz4nm5rv7g]

Is the plastic like thing inside the squid the same as that of a crab?

[@marcusbullock630]

yes, in a way. youre thinking of the cuttlebone. both squid and crabs have an internal skeleton

[@opala743]

Does this hurt the crab???

[@Mahid6079]

Nah

[@simplewormonastring6869]

They were not alive during the video, so they did not feel any pain.

[@JohnsonLong-l6w]

1:39 I play with it like this when i was a kid 😁

[@GionfrancoBarrientos]

Wht

[@txwombat7826]

Thats called playing with your food.

[@NandarAung-wl8ln]

I thought it was bone before

[@youlookcool]

for the ppl who watched the shark dissection 💀☠

[@BobrLovr]

how tf do you even know that exists, you just cutting crabs apart in your free time? 😂 Someone call peta

[@MeniscoManeiro]

I'm done with the childish noises. Unsub

[@gooner7768]

This is micro plastic digested by crabs. Cuttlefish and squids also have these. I am lying.

[@demonicdice1017]

Been a while i don't see your content on my feed.
