Needle apertures (4)
I believe the answer is:
eyes
'needle apertures' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eyes that I've seen before include "(Paradoxical?) film with Cruise and Kidman" , "Narrowly observes" , "They have pupils" , "Closely looks at" , "Visual organs" .)
