Squids do have bones in their body.
Although the bones the squid has is not the same as a humans bones or other animals skeleton system.
The squid does have a skeletal system and skeleton in the form of a rod-like gladius or pen, made of chitin.
Squids are soft bodies creatures though.
If you cut into a squid you'll notice some bones but they will be very different than human or other animal bones.
I helped open up a squid in science class many years ago and remember the skeleton system in the squid so they do have a form of bones.
But they were not very large and were pretty brittle.
Some people also eat squid but I don't think I ever will.
