Barbour's map turtle (Graptemys barbouri) is a species of turtle in the family Emydidae. The species is native to the southeastern United States.

Geographic range

G. barbouri is found in rivers located in southeastern Alabama, the western panhandle of Florida, and southwestern Georgia.^[4]

Habitat Preference

G. barbouri have been shown to prefer areas in deeper water, close to rocky areas with large amounts of woody debris.^[5]

Etymology

The specific name or epithet, barbouri, is in honor of American herpetologist Thomas Barbour.^[6]^[7]

Ownership

Owning Barbour's map turtle is illegal in Georgia, Michigan, and Alabama. The limit is two turtles per person in Florida. Like all map turtles, it is under the protection of the Salmonellosis Four-inch Regulation, disallowing G. barbouri to be sold if it is under the length of 4 in (10 cm).

Description

Adult male Barbour's map turtles are on average 3.5 to 5.5 in (8.9 to 14.0 cm) in straight-line carapace length. Adult females are much larger and can vary from 6 to 12.5 in (15 to 32 cm) in straight-line carapace length. "Females attain really imposing dimensions, and their heads are enormously enlarged".^[4] G. barbouri possesses black-tipped spines on the second, third, and fourth vertebral scutes. These spines are very noticeable in males, and resemble a dorsal fin.

Diet

Barbour's map turtle mainly consumes mollusks, insects, and small fish found in rivers.
