Alabama sturgeon
The Alabama sturgeon, ''Scaphirhynchus suttkusi'', is a critically endangered species of sturgeon native to the United States of America and now only believed to exist in of the lower Alabama River. The fish has a distinctive yellowish-orange color, grows to a size of about 30 inches long and 2 to 3 pounds, and is believed to have a lifespan of 12 to 20 years. Biologists have known of the fish since the 1950s or 1960s, but the large diversity of aquatic species in Alabama prevented formal identification until 1991.
== Protected status controversy ==
The Alabama sturgeon was first proposed for protected status in the early 1990s, although by then the fish was already so rare its survival was uncertain. The sturgeon's protection was opposed by a variety of industries located along Alabama's rivers for the feared economic impact. The opponents' main arguments were that it was already extinct or that it was not a distinct species. In response to this opposition, the U.S. Fish and Wildlife Service ceased efforts to place the fish on the Endangered Species List. Then Ray Vaughan, an environmental lawyer in Montgomery, Alabama, sued the Service and, in 2000, won, requiring Fish and Wildlife to list the fish for protection.〔
