PBS- The Joy of Pigs
http://www.pbs.org/wnet/nature/pigs/index.html
Ever heard the expression "sweat like a pig"? The truth is that pigs are actually unable to sweat! PBS's website section dedicated to "The Joy of Pigs" is great for learning the truths about pigs, from how they actually cool themselves down to how intelligent they are, despite what you may have heard!
