Target for lion, perhaps, little creature has run off with another (8)
I believe the answer is:
antelope
'target for lion perhaps' is the definition.
'little creature has run off with another' is the wordplay.
'little creature' becomes 'ant' ().
'has' says to put letters next to each other.
'run off with another' becomes 'elope'.
'ant'+'elope'='ANTELOPE'
(Other definitions for antelope that I've seen before include "Gazelle or impala" , "Wild creature" , "One leapt badly on the graceful animal" , "'Gazelle or gnu, say (8)'" , "eg Eland" .)
