Morphology

brachiopod = brachio + pod (opaque) = brachio + pod

While 'brachio' and 'pod' are recognizable elements, the specialized biological meaning is not transparent to learners without specific knowledge.

Etymology

Brachiopod comes from Greek parts brachi- meaning 'arm' and -pod meaning 'foot', because these shell animals have arm-like parts for feeding and a foot or stalk. So a brachiopod is a sea animal with a shell whose name points to its 'arms' and 'foot'.
