I suggest "bug" applies exclusively to chitinous invertebrates.

I'm trying to square my instinct that

snails aren't bugs (because they're squishy without the shell) with the feeling that
crabs are bugs (because they'd go tap-tap if you tapped on their exoskeleton with a finger) but
hermit crabs aren't bugs if they're in a shell but are bugs if they're naked

Snail shells aren't chitinous.

Crab shells are chitinous.

Hermit crabs are only partly chitinous, and the shells they use are not chitinous.

Hope that helps
