Morphology

rock + barnacle

The meaning 'a barnacle that attaches to rocks' is directly and transparently derivable from combining 'rock' (stone) with 'barnacle' (a sessile marine crustacean). This noun-noun compounding follows regular English composition patterns and is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Rock barnacle is a plain, literal name: it describes a barnacle that lives on a rock and clings tightly by the sea. So the name means 'a barnacle that attaches itself to rocks', and the image of a hard shell stuck to stone makes it easy to remember.
