Morphology
The compound 'acorn barnacle' is transparently compositional: a B1 learner who knows 'acorn' (a small nut with a distinctive shape) and 'barnacle' (a sessile crustacean) can infer it is a barnacle shaped like an acorn. This straightforward noun+noun naming pattern is common across languages and thus easily predictable from the constituents.
Etymology
The name acorn barnacle comes from how this little sea animal looks: its hard shell is shaped like an acorn. Like other barnacles, it 'sticks' tightly to rocks, so the name tells us it is a small, cone-shaped barnacle that clings to the shore.
