These have a liitle dofference that they are orfen radially symmetrical. some of have internalised some their originally moving and feeding appendages and created a organ that can push water rapidly from one end of the shell. This is a very common trait that evolved convergently in many organisms of Temere. Some species use it to better feed in the detritus, some use it as a means of escape. The other difference of Raadiopods is that their shells have more pieces than just one. Here for example the other pieces form operculums, so the animal can seal its limbs inside the shell. Or the spiral-like species uses the shell pieces as ,,claws" for digging in the substrate.
