   do they have an inflexible shell-like skeleton like a cowfish? or maybe more of an internal strutwork like a sunfish?

   or maybe they are put together a bit more like an invertebrate. crab shells might be good reference..

     also how the heck do their mouths work if they have a rigid internal skeleton? you want a good solid support for the arms, which seems to preclude a closing central mouth as depicted in a lot of the art. maybe they have jawless mouths with internal moving parts like a lamprey.
