Are snails and nautilus related?
Nautiluses are cephalopods. They are different from their living cephalopod relatives, though, in numerous characters, which make them appear like a relic from times long gone: Other than a snail shell, a nautilus shell is chambered inside; the animal itself inhabits only the outermost, apertural chamber.
