Animal turned peripatetic to some extent (5)
I believe the answer is:
tapir
'animal' is the definition.
(I've seen this before)
'turned peripatetic to some extent' is the wordplay.
'turned' says the letters should be written backwards.
'to some extent' indicates a hidden word.
'ripat' is hidden within 'peripatetic'.
'ripat' in reverse letter order is 'TAPIR'.
(Other definitions for tapir that I've seen before include "Long-nosed, hoofed mammal" , "nocturnal beast" , "Ungulate" , "Nocturnal mammal with a short flexible proboscis" , "I part with the pig-like animal" .)
