ST. PETERSBURG, Fla. (AP) A large sawfish that showed signs of distress was rescued by wildlife officials in the Florida Keys, where more than three dozen of the ancient and endangered fish have died for unexplained reasons in recent months.

The 11-foot (3.3-meter) smalltooth sawfish was seen swimming in circles near Cudjoe Key and reported by a member of the public to the Florida Fish and Wildlife Conservation Commission, officials said Friday. It was loaded onto a specially designed transport trailer and taken to Mote Marine Laboratory in Sarasota, where it is being rehabilitated.
