Morphology

freshwater + mussel

The meaning is directly and transparently derived from combining 'freshwater' (non-salty water found in lakes and rivers) with 'mussel' (a bivalve mollusk) — i.e., a mussel that lives in freshwater habitats. This straightforward compositional pattern is common across languages, so a B1 learner who knows both constituents would readily understand the term.

Etymology

The compound noun freshwater mussel names a mussel that lives in rivers and lakes rather than the sea. The part freshwater means 'fresh water' not 'salt water' and mussel is the shellfish, so the name tells you it is a shellfish that lives in fresh water.
