Morphology

sea + creature

The meaning 'an animal that lives in the sea' is directly and compositionally derived from 'sea' (saltwater body) + 'creature' (animal), so a B1 learner who knows both words can infer the MWE. This noun‑noun compounding is a common, cross‑linguistic pattern and follows standard English composition rules, making it immediately understandable.

Etymology

Sea creature comes from the simple picture of a creature living in the sea, like a fish, whale, or octopus. So, it means 'an animal that lives in the sea'.
