Morphology

oyster + crab

The meaning is directly compositional: 'oyster crab' denotes a crab associated with oysters (i.e., a crab that lives in or on oysters), so a B1 learner who knows 'oyster' and 'crab' can infer this. Noun–noun compounds that indicate type or association are common in English and cross-linguistically, making the expression transparently interpretable even if the exact biological detail is new.

Etymology

Oyster crab gets its name from a clear picture: a tiny crab living inside an oyster's shell. That's why the name means 'a small crab that lives inside the shell of an oyster'.
