Friday, May 19 is Endangered Species Day. Not just in Knoxville. The U.S. Postal Service is celebrating the 50th anniversary of the Endangered Species Act by releasing a collection of stamps featuring endangered animals and fishes. All 4,000 of the Endangered Species Limited Edition Collector's Sets are already sold out, but other collector items are still available. The fish were photographed by Joel Sartore, a friend of local nonprofit Conservation Fisheries. His National Geographic Photo Ark collection also features boulder darters, which are native to the Elk River in Middle Tennessee and have been federally listed as endangered since 1988.

Here’s another link to the celebration: Endangered Species Day in the Old City.

Join in various festivities, ranging from Riverside Tattoo Flash Day to Pint Night at Merchants of Beer to honor those critters who may not be with us much longer.
