Morphology

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

Formed by compounding 'single' + 'shelled' (shell + -ed); the meaning 'having one shell' is directly inferable from the parts.

Etymology

Single-shelled combines single ('one') and shell ('a protective covering'), so imagine a creature with just one outer shell. That's why single-shelled describes animals, like many snails, that have only one shell.
