The Marine Mammal Conservancy (link) is a non-profit 501 (c) (3) IRS designated organization located in Key Largo, Florida. Their mission is to rescue, rehabilitate, and release stranded marine mammals, as well as to provide a suitable “retirement” location for animals that may not be suitable for release. Their most recent success story involved 11 rough-toothed dolphins who were stranded off of Marathon Key on March 2, 2005. These dolphins were successfully rehabilitated and released back into the environment on May 3 and September 12 2005.
This was the largest, and most successful, simultaneous release of marine mammals to date. For information about their program, volunteer opportunities, or donations, please visit their website at Marine Mammal Conservancy.
