The reason sharks have no bones
The frame of sharks is made up of cartilage, not bones, allowing them to move flexibly under water.
Why do sharks have no bones?
Thanks to the flexibility of cartilage, sharks can swim very fast.
Sharks belonging to the special animal class are called cartilage (Chondrichthyes) . Their frames are not made up of bones but from cartilage (cartilage) . What is that?
It is the same thing that forms our ears and nose. It is thanks to this flexible material that sharks can work skillfully underwater. But how?
Cartilage is not as dense as bone, so it is much lighter. Lighter weight helps sharks float in the water. In addition, thanks to the versatility of shark cartilage, it can swim very fast, helping them catch prey as well as saving energy.
In addition, the studies also showed that the cartilage framework is faster than the skeleton. So you understand why sharks don't have bones !!!
