No sharks do not have bones.
Sharks do have skeletons, but they’re made of cartilage rather than bone. Cartilage is the flexible stuff in the tip of your nose. A cartilage skeleton has its advantages. It’s light, flexible, and it heals faster than bone. In some spots though, sharks need a little extra strength. Their skulls, jaws, and spine are fortified with calcium salts, making them much thicker and stronger. Can you think of why a shark would need strong jaws, skulls, and spines?

This settles a recent argument – discussion? – anyway, difference of opinion about shark spines and their ability to snap back their heads to their tails. Ha! I win! I wish I’d had this ammo at the time… RH

SHARKS DO HAVE BONES!!
Sharks have cartilage which makes up their skeleton. Cartilage is a tissue that is often a component of bone, but sharks do not have the dense bones we have as a skeleton.
Sharks are koalas!!!!
