Gazelle or springbok (8)
I believe the answer is:
antelope
I believe this is a double definition.
'gazelle' is the first definition.
(I've seen this before)
'springbok' is the second definition.
(thesaurus)
(Other definitions for antelope that I've seen before include "Springboks, say" , "eg Eland" , "Animal related to goat" , "grazing animal" , "A graceful gazelle from Africa" .)
