Are you serious? They really have what amounts to an exoskeleton? Or maybe it’s more accurate to call it a whole-body rib cage?
Just searched and found this fun article. Not really a skeleton but a collection of really stiff hairs or feathers (loosely: the genes are the same ones responsible for “other skin appendages” in vertebrates).

Looks like it’s fake. This research paper shows a more normal skeleton, though they do apparently lack ribs and a pelvis.
I think it’s just inaccurately labeled as a skeleton. These appear to be skin spikes. https://www.cell.com/iscience/pdf/S2589-0042(19)30185-3.pdf
