I have long known sharks have cartilaginous skeletons but only just wondered whether that means shark bodies are squishy like human ears? Like if you hugged a shark would it deform?
- DoreenMichele 3y agoI don't know but I wouldn't recommend trying it, at least not without wearing chain mail. Their skin is abrasive if you hug them and call them George and rub their skin backwards.
- hn_throwaway_99 3y agoNo. The human nose is mostly cartilage and it's hard.
- edgyquant 3y agoIt’s pretty soft compared to bone. I can push mine half way down to the skin.

- Calavar 3y agoThe lower half of the nose is cartilage and is pretty soft. The upper half of the nose hard and is bone.
- BuildTheRobots 3y agoThis is probably a stupid question, but if the upper half of the nose is bone, why does a human skull seem to always have a hole where the nose is?
- thfuran 3y agoBecause the bottom half isn't bone and the whole thing is hollow.
- AlotOfReading 3y agoThat's where the cartilage was. You can find that hole in your own skull easily enough. There should be a small bump midway up your nasal ridge. That point is called the rhinion. Everything above it is laying on your skull. The parts of the nose below it cover your nasal cavity.
- Retric 3y agoAnatomically correct skulls have an hole where the bottom of your nose is and the eyes are both smaller and higher up than you probably think. https://en.wikipedia.org/wiki/Orbit_(anatomy)#/media/File:Eye_orbit_anatomy_anterior2.jpg https://en.wikipedia.org/wiki/Orbit_(anatomy)#/media/File:Ey... Looking at yourself in a mirror, if you hold your finger over the top of your nose your eyes will see under your finger. Move your finger just low enough so you’re seeing over it and you should be touching the bottom of your nasal bone. At that point your nose should be more than a finger width froward from the bottom of your orbital socket which is where the hole in skulls starts in those skulls.
- Calavar 3y agoLook at a picture of a skull in profile. You'll see that there is half a nose, not no nose. That half of the nose that you can see is the bony part. The missing half is the cartilaginous part. Why is there a hole? Because your nasal canal extends inside your skull to connect with the back of your throat. I guess I don't fully understand the question there.
- colordrops 3y agoYeah you (well, I) can feel a distinct line between the bone and cartilage.
- Moto7451 3y agoWhile you can’t hug them, see if your nearest aquarium has a touch tank experience. Usually they do those with rays/skates but you can also find them with Nurse sharks. Either way, you’ll literally get a feel for their composition. From memory it’s more like the stiff parts of your nose running near/along the bone and unlike your ears in any way.
- darkerside 3y agoMy guess is that, yeah, if you empty them of water
