Imaginably, a hunted animal (5)
I believe the answer is:
snark
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for snark that I've seen before include "Hunt creature (Carroll)" , "creature fitly hunted" , "Animal hunted in verse" , "Carroll's mythical animal" , "Creature charmed with smiles and soap" .)
