Morphology
The meaning is directly and transparently derived from 'chambered' (having distinct chambers) modifying 'nautilus' (a marine cephalopod with a spiral shell). A B1 learner who knows both constituents will readily infer it refers to a nautilus with internal chambers, since this follows a regular adjective + noun compositional pattern.
Etymology
Chambered nautilus is the name for a sea animal with a spiral shell full of little rooms, which is why it is called chambered for its inner 'chambers'. The word nautilus comes from a word meaning 'sailor' because the animal drifts and moves in the water like a tiny boat, so the name helps you remember both its shelled rooms and how it lives.
