Gorilla or orangutan (3)
I believe the answer is:
ape
This clue is a double definition.
'gorilla' is the first definition.
(gorillas are apes)
'orangutan' is the second definition.
(orangutans are apes)
(Other definitions for ape that I've seen before include "Take off" , "Our cousin" , "Simulate" , "Anthropoid primate" , "Wild animal" .)
