Animals, small, turned up round area (6)
I believe the answer is:
llamas
'animals' is the definition.
(I've seen this before)
'small turned up round area' is the wordplay.
'turned up' shows that the letters should be reversed in order.
'round' indicates putting letters inside.
'area' becomes 'a' (maths abbreviation).
'small' reversed gives 'llams'.
'llams' enclosing 'a' is 'LLAMAS'.
(Other definitions for llamas that I've seen before include "Camel-like animals" , "South American pack animals" , "Sal and Mal for the animals" , "South American cud-chewing animals" , "S American animals related to the camel" .)
