Right! No heroics when moving wild animal (10)
I believe the answer is:
rhinoceros
'wild animal' is the definition.
'right no heroics when moving' is the wordplay.
'right' becomes 'r' (common abbreviation).
'when moving' is an anagram indicator (I've seen this in other clues).
'no'+'heroics'='noheroics'
'noheroics' anagrammed gives 'hinoceros'.
'r'+'hinoceros'='RHINOCEROS'
(Other definitions for rhinoceros that I've seen before include "Large horned animal" , "Brute" , "Black/white horned herbivore" , "Horny character" , "Big game" .)
