Morphology

cephalochordate = chordate (semi-transparent) = cephalo + chordate

Formally built from the combining form 'cephalo-' + 'chordate', but both elements are technical biological terms and the composition is unlikely to be intuitive to an average B1 learner.

Etymology

Cephalochordate comes from Greek parts cephalo- ('head') and -chordate ('cord' or 'string'), like the English word cord. So a cephalochordate is an animal with a 'head' and a long inner 'cord' called the notochord running along its body, which is why it has a cord instead of a true spine.
