Actually some "squid" have a skeleton of sorts. Cuttlefish have this porous thing that sort of resembles a hunk of pumice. Chunks of it are sold for use as some for birds to sharpen(?) their beaks on.

Sponges *do* have skeletons. The kind we use as sponges have one made of cellulose. That's the "sponge" part.

There are also "glass sponges" that use silica instead. They look like abstract glass sculptures.

Either sort, you have to let the body rot away to get the "sponge" part.
