Sharks have no bones in their body!
Their skeleton is made of cartilage, the same substance that your nose is
made of. It's more flexible and lighter than bones are. This makes it more
durable, and light, which saves them energy. This is particularly useful
because sharks have to constantly swim in order to not drown. Sharks also
lack a rib cage, which means that they can be crushed by their own weight
on land!
Now you know. Next time a shark's about to eat you, you can at least be
consoled that it's a spineless animal. Or you could get Orcas to help you
