About the time I think I've seen everything, I run across something that is truly puzzling, like the article with photos on "Animal Suicides". Talk about a freak of nature.
What I found most astounding is the story of 61 pilot whales washing ashore. Some were already dead before they reached land, but when the survivors were pushed back to sea, they actually swam back to shore only to die with the rest of their group!
