Morphology

lamellibranch = lamella + branch (opaque) = lamelli + branch

The word is derived from scientific Latin, and the components 'lamelli' and 'branch' do not transparently convey the meaning of a bivalve mollusk to an average learner.

Etymology

Lamellibranch as an adjective comes from the same parts: lamelli- 'thin plates' and -branch 'gills', and it describes shellfish or fossils that have plate-like gills. So calling a fossil or shell lamellibranch means it belongs to clams, oysters, or mussels with two shells and thin gills.
