Natator is a monotypic genus that includes only one species, Natator depressus, commonly known as the flatback sea turtle. This marine turtle is native to the waters of Australia and is unique among sea turtles for its relatively flat shell and restricted range. Unlike other sea turtles, flatbacks have a softer carapace and lay fewer but larger eggs. They prefer shallow coastal waters, feeding on soft-bodied invertebrates like jellyfish and sea cucumbers.
