Back to  Do spiders and worms and flies have bones?

Good question. We asked our biologist Marisa R. to give us an answer and here it is.


But you probably wanted more than just a yes or no, so we asked Marisa to explain.

Spiders and flies and all the insects do have a skeleton. The skeleton of insects and spiders is on the outside of their body and it is called an exoskeleton. It is made of several substances, the best know is called chitin.

The exoskeleton is lighter and stronger than bone and serves as a suit of armor that protects the internal organs.

You can get more information from The World Book Encyclopedia volume 10 in the school library
