Morphology

crustaceous = crust (opaque) = crust + aceous

The word is formed with the recognizable element 'crust' and the learned suffix '-aceous', but the zoological sense is specialized and not straightforwardly predictable.

Etymology

Crustaceous is related to crustacean, the group name for animals like crabs and lobsters, and to crust, meaning 'a hard outer shell'. So crustaceous means 'relating to' or 'like' crustaceans, which is why we use it for crabs, lobsters and similar animals.
