The tulotoma snail, or Tulotoma magnifica, is a small, aquatic snail believed to exist only in the lower Coosa River drainage of Alabama. Classed by biologists in 1991 as endangered, the snail has made a bit of a comeback thanks to federal protection. Since then, its habitat has increased from 2 percent of its original range to 10 percent.

 

Today, its status has been raised from endangered to threatened. However, it still remains vulnerable because of drought, spills and pollution that can ravage its watershed home.
