Morphology

Aplacophora = Placophora (opaque) = a + placo + phora

Although formed from Greek elements meaning 'without' + 'plate-bearing', the combining forms are specialist and not helpful for average learners to infer the meaning.

Etymology

Aplacophora comes from Greek parts a- 'without', placo 'plate', and -phora 'bearing'. So, Aplacophora means 'bearing no plates', which explains why these mollusks have no shell plates and look worm-like.
