Morphology

hard-shelled = hard + shelled (transparent) = hard + shell + ed

The adjective is a straightforward compound of 'hard' + 'shelled' (where 'shelled' = shell + -ed), yielding the literal meaning 'having a hard shell'.

Etymology

The word hard-shelled is made from two plain parts, hard ('firm') and shell ('outer cover like a nut or egg'). So it pictures something with a firm outside that protects the inside, which is why we use it for animals or plants that have a hard outer shell.
