"Federal agencies have changed the designation of loggerhead sea turtles from a single threatened species to nine distinct population segments; five are listed as endangered and four are listed as threatened.
The National Oceanic and Atmospheric Administration and U.S. Fish and Wildlife Service said the change will help scientists tailor conservation efforts to deal with threats faced by genetically distinct groups of the species in regions around the world.
The decision Friday was in response to legal petitions filed in 2007 by the Center for Biological Diversity, the Turtle Island Restoration Network and Oceana for additional protections for the loggerheads."
