Morphology
The phrase combines the general noun 'order' (a taxonomic rank) with the taxon name 'Actiniaria', so its meaning — the taxonomic order named Actiniaria, i.e. sea anemones — is directly derivable from the constituents. This follows a regular, cross-linguistic scientific naming pattern (e.g. 'order Primates'), making it transparent to learners who know both words.
Etymology
Order Actiniaria may come from a Greek word meaning 'ray' because these animals have many tentacles that spread out like rays around a central mouth. That's why the name is used for the scientific group of 'sea anemones'.
