Easy shot bagging stray animal (8)
I believe the answer is:
terrapin
'animal' is the definition.
The answer is an example.
'easy shot bagging stray' is the wordplay.
'easy shot' becomes 'tapin' (a tap-in is an easy shot eg in football).
'bagging' means one lot of letters goes inside another (I've seen this in other clues).
'stray' becomes 'err' ('err' can be a synonym of 'stray').
'tapin' placed around 'err' is 'TERRAPIN'.
(Other definitions for terrapin that I've seen before include "Swimmer" , "Water tortoise" , "A reptile; a printer (anag.)" , "Hardback" , "Small freshwater turtle" .)
