The ringed map turtle or ringed sawback (Graptemys oculifera) is a species of turtle in the Emydidae family endemic to the southern United States.

Geographic range[edit]

It is found only in the Pearl River system in Louisiana and Mississippi. It shares this range with the Pearl River map turtle (G. pearlensis).


Males may attain a carapace length of 10 cm (4 in). Females are larger, and may attain a carapace length of 22 cm (8.5 in). On the carapace are light-colored rings, which are thicker than the rings on Graptemys nigrinoda.[4]
