Greedy; predatory (9)
I believe the answer is:
rapacious
I believe this clue is a double definition.
'greedy' is the first definition.
(I've seen this before)
'predatory' is the second definition.
(I know that predatory can be written as rapacious)
(Other definitions for rapacious that I've seen before include "Aggressively greedy" , "Aggressively predatory" , "Marauding, avaricious" , "wanting more" , "Extortionate" .)
