ribless
Lacking bony supports
Ribless means lacking ribs.
The word applies to anatomy—certain fish and amphibians are ribless—or to cuts of meat: ribless pork loin.
It can describe objects designed without rib-like supporting structures: a ribless umbrella, ribless knitting produces a smoother fabric.
