Jellyfish or hawks? (3-2-3)
I believe the answer is:
men-of-war
'hawks?' is the definition.
The answer and definition can be both animals as well as being plural nouns.
Maybe there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for men-of-war that I've seen before include "Fighting ships" , "Armed sailing ships" .)
