Antelope seen in country, not Iran (5)
I believe the answer is:
eland
'antelope' is the definition.
(eland is a kind of antelope)
'country not iran' is the wordplay.
'country' becomes 'Ireland' (Ireland is a country).
'not' indicates named letters should be taken away.
'iran' becomes 'ir' (eg in website addresses).
'ireland' with 'ir' removed is 'ELAND'.
'seen in' is the link.
(Other definitions for eland that I've seen before include "South African antelope" , "Spiral-horn antelope" , "Large African deer with short spiral horns" , "wild creature" , "Wild beast" .)
