Wild animals that may be camouflaged when crossing? (6)
I believe the answer is:
zebras
This clue is a double definition.
'wild animals' is the first definition.
(zebras are wild animals)
'that may be camouflaged when crossing?' is the second definition.
(as in a zebra crossing)
(Other definitions for zebras that I've seen before include "Striped mammals" , "Black-and-white striped African equines" , "Black and white African animals" , "Black and white equines" , "Striped horse-like animals" .)
