A Human skeleton,and a crab shell are alike because,the bones inside the human body are strong like the crab shell on the outside of the body
The skeleton and shell of a crab are synonymous. What we'd call the shell of a crab is simply a component of its exoskeleton, the external covering arthropods use made out of a tough protein, chitin.

Not internally. They have what is called an exoskeleton. It's a sort of skeleton that covers the outside of the crab on his legs and head. This means that they have to shed this skeleton and regrow a new one as they get older so that they can get bigger.
A crab has an external hard shell, and is an invertebrate.
