A shark's skeleton is made up of cartilage.
Cartilage
Yes, sharks are indeed animals that have cartilage instead of bones. Their skeletons are made up entirely of cartilage, allowing them to be more flexible and lightweight compared to other animals with skeletons made of bone.
Cartilage
We do not have shark cartilage because then we would be sharks and I do not want to be a shark or have any shark cartilage in me at all.
Sharks do not have bones, they have skeletons made of cartilage.
A shark's "skeleton" is made of cartilage while human skeleton is made of bone.
I believe the shark is made up completely of cartilage, such as your ear. SuperSlasher
sharks are made of human poo and it is a true fact
Sharks are cartilaginous fish. The term "cartilaginous fish" means that the structure of the animal's body is formed of cartilage, instead of bone. A shark does not have one bone in it's body. It's skeleton is made up of cartilage. Cartilage is a tough material, like the material that shaped your ear.
No, because a shark is not a bony fish as it's skeletal structure is made of cartilage.
cartilage is more flexible than bone making the shark more hydrodynamic.
