Still Waters Posted October 31, 2013 #1 Share Posted October 31, 2013 Arctic reindeer can do something no other mammal can, though to be fair not many mammals can survive on the North Pole.

They have brownish golden eyes in the summer (to counteract 24 hours of sunlight) and switch to blue in the winter to help see in the darkness. http://www.universit...-the-summer.htm Link to comment Share on other sites More sharing options...
