Morphology

dibranchiate = branchiate (semi-transparent) = di + branchi + ate

The formation di- (two) + branchiate (having gills) is morphologically regular, but both elements are technical and unfamiliar to most learners.

Etymology

Dibranchiate comes from the prefix di- meaning 'two', as in bicycle, and branchia meaning 'gills', so it literally means 'two-gilled' and describes sea animals like squids and octopuses that have two gills.
