Pearl River Map Turtle
Discovered in 2010, this turtle species is listed on the IUCN Red List as endangered. It is named for the river where it lives. The Pearl River flows down through central Mississippi and forms the state's border with Louisiana. The females of this species are 6-11 inches in diameter while the males are 4-6 inches in diameter. This allows the males and females to have different food sources, ranging from small insects to clams and other mollusks.
