Morphology

Actinozoa = actino + zoa

A technical compound made from Greek combining forms ('actino-' + '-zoa') that are not independent modern English words, so the meaning is not derivable by an average learner from familiar English vocabulary.

Etymology

Actinozoa comes from the Greek parts actin- meaning 'ray' and -zoa meaning 'animals', and you can think of zoo for the 'animals' part. These sea creatures, like corals and anemones, have bodies and tentacles that spread out like rays or the spokes of a wheel, and they do not have a free-swimming jellyfish stage, which is why the name fits them.
