Morphology
actiniarian = actinia (opaque) = actini + arian
The word relies on specialized taxonomic vocabulary and orthographic adjustments (the final vowel of 'actinia' is dropped), so an average B1 learner would not reliably derive the meaning from the parts.
Etymology
Actiniarian comes from the sea-anemone name Actinia, which uses the Greek root actin- meaning 'ray' because these animals have many ray-like tentacles. So actiniarian means a sea anemone or an animal like a sea anemone.
