Europeans found in the Arctic and Antarctic? (5)
I believe the answer is:
poles
'europeans' is the definition.
(Pole is an example)
I don't understand the rest of the clue.
(Other definitions for poles that I've seen before include "People from Warsaw?" , "Nationality of citizens of Warsaw" , "Extremities of the earth's axis" , "Rods of wood or metal" , "North and south" .)
