I thought this was pretty cool: [From Greek ostrakizein, from ostrakon (shell or potsherd), from the fact that in ancient Greece these were used as ballots in voting to banish someone. Ultimately from Indo-European root ost- (bone) that gave birth to such words as oyster, osteopathy, ossify, and Sanskrit asthi (bone).] As soon as I got to "shell" I thought "oyster", and ...sure enough! Though somewhere along the way, the inner- and outerness of bones got confused...? To me, a bone is by definition on the inside but a shell would be outside.

Not that confused, Jackie, considering that a shell is called (yes, I think of it as being in an explanatory way) the exoskeleton.

thanks, Joma, i meant to get back here and post that--the exto-skeleten its not so evidently a skeleten in an oyster--but very evident in say a lobster--(or for that matter in insect)
squids, octopuses and cuttle fish are interesting.. they have a beak or cuttle bone-- in many ways, a remnent of a shell-- but beginning to get internal (especially in the cuttle fish) skeletens...
nautalus-- are also related-- but they still 'reside' in an external shell--
in many animals, claws and hoofs are part of the skeleten-- but in primates, claws have been replaced by finger nails-- no bony parts to the claw at all.
claws often have tips that are the same protien as finger nails, but they start as bone, with nails on the tip.--a small portion of skeleton extends outside of the body.
(some lemors, still have claws on hind feet, but fingernails on 'hands'--they are 'lowest members of primate family)

I don't know if they have any claws on their hind feet but they got crooked nails on their sticky hands and they have voted Democrat in every election since Reconstruction. Yep, first class low life!
