Morphology

actinozoan = actino + zoan (opaque) = actino + zoan

Both elements are specialized scientific combining forms rather than familiar standalone English words, so a B1 learner cannot reliably infer the meaning.

Etymology

Actinozoan comes from Greek parts actino- meaning 'ray' and -zoan meaning 'animal'. Think of actino- as rays spreading from a center and -zoan like zoo, which is about animals. That's why actinozoan names sea animals such as corals and anemones that have tentacles or arms spreading out like rays.
