Morphology

sea + otter

The meaning 'a marine otter' is directly and compositionally derived from 'sea' (saltwater body) + 'otter' (small web-footed carnivore); this noun‑noun compound signals habitat and is a straightforward, literal combination. Such compounding is cross‑linguistically common, so a B1 learner who knows both words can readily infer the MWE's meaning.

Etymology

Sea otter gets its name from the simple image of an otter that lives in the sea. These animals float on their backs and use rocks to open shellfish, so the name helps you remember it is an otter of the ocean.
