Park removed arboreal carnivore (5,4)
I believe the answer is:
polar bear
'carnivore' is the definition.
(polar bear is a kind of carnivore)
'park removed arboreal' is the wordplay.
'park' becomes 'p' (this might be a standard abbreviation which I don't know about).
'removed' indicates an anagram (moved again).
'arboreal' is an anagram of 'olarbear'.
'p'+'olarbear'='POLAR BEAR'
Can you help me to learn more?
(Other definitions for polar bear that I've seen before include "Arctic pack ice resident" , "Arctic creature" , "Beast of the Arctic" , "Arctic carnivore" , "Arctic-dwelling mammal" .)
