Morphology

Cephalochordata = Chordata (opaque) = cephalo + chordata

Scientific taxon formed by adding the combining form 'cephalo-' to the taxon name 'Chordata'; the parts are technical and not transparently meaningful to an average B1 learner.

Etymology

Cephalochordata comes from Greek parts cephalo- meaning 'head' and -chordata meaning 'cord'. So the name points to animals like lancelets that have a long 'notochord' or backbone-like cord near the head and keep it throughout life.
