The diamondback terrapin is found along the Atlantic Coast of the eastern United States from Cape Cod to the Florida Keys and west along the Gulf Coast to Texas. Of the 250 species of turtles in the world, the diamondback terrapin is the only species to inhabit exclusively in estuarine environments and females are 75% larger than males! The ornate diamondback terrapin is found throughout Collier and Lee counties.
It is the same genus and species as other diamondback terrapins (Malaclemys terrapin), but it is a separate subspecies (Malaclemys terrapin macrospilota). It is genetically similar enough that it could breed with other diamondback terrapins and have viable offspring, but it's appearance is different enough that it is a subspecies.
