Animal skin to be treated (8)
I believe the answer is:
steinbok
'animal' is the definition.
The answer is an example.
'skin to be treated' is the wordplay.
'treated' indicates anagramming the letters.
'skin'+'to'+'be'='skintobe'
'skintobe' with letters rearranged gives 'STEINBOK'.
(Other definitions for steinbok that I've seen before include "one ruminates" , "example of African fauna" .)
