Morphology

epibranchial = branchial (semi-transparent) = epi + branch + ial

The prefix 'epi-' meaning 'above' or 'upon' is clear, but the specialized anatomical context may not be immediately obvious to all learners.

Etymology

Epibranchial breaks into epi- meaning 'on' or 'above' and branchia meaning 'gills', the same idea as the common English word 'gill'. So, used as an adjective it describes something that is 'above the gills'.
