Horseshoe crabs' blue blood, which contains copper, not iron, is prized by the biomedical community for its ability to detect bacteria in human medicines. It's just one of the amazing qualities of the 350-million-year-old evolutionary marvel detailed in "Crash: A Tale of Two Species."

"Crash: A Tale of Two Species" airs on PBS Sunday, March 20, 2011 at 8pm (check local listings) and is part of the 28th season of the Peabody and Emmy award-winning series produced by Thirteen in association with WNET.ORG for PBS. Major support provided by Canon U.S.A. Inc. http://www.pbs.org/wnet/nature/episodes/crash-a-tale-of-two-species/introduct...
