Polar Bears and Infrared film question

[flzhgn@xxxxxxxxxxxxx (Norma Foltz & Thomas H. Hogan)]

  I think I remember something about polar bears and infrared 
photography.  Does anyone recall reading about polar bear fur
having special properties with infrared light and a discovery
by somed Canadian wildlife biologists with aerial photography.

I went down to the San Diego Zoo a few weeks ago, and took a 
roll of HIE film of some polar bears at the Polar Plunge 
exhibit.  I used mostly a 500mm mirror lens, tripod and HC110
dilution B for development.  Should I be looking for something
special in the photos ?  I tried to take the same shots on 
color slide film...  Hank
