Center for Biological Diversity: SAN JUAN, Puerto Rico Conservation groups filed a legal petition today urging the U.S. Fish and Wildlife Service to revise protected critical habitat for the leatherback sea turtle (Dermochelys coriacea) under the Endangered Species Act. The petition asks the wildlife agency to protect three important leatherback nesting beaches in Puerto Rico and to consider the addition of other important nesting beaches for this species on the island.
