Morphology
river + limpet
The compound 'river limpet' is a straightforward noun–noun composition where 'river' specifies the habitat of the head noun 'limpet' (a small conical mollusk). Because the meaning is directly built from the constituents and follows a common cross-linguistic pattern of habitat-based compounds, a learner who knows both words can derive the MWE's meaning.
Etymology
The name river limpet comes from small snails that look like a sea limpet but live in a river. They have a low, cone shell and cling tightly to plants or rocks, so people called them 'river limpets'.
