Escambia Map Turtle vs. Barbour's Map Turtle

The two meet, and hybridise, in the Pea and Choctawhatchee rivers; FNAI calls them difficult even for experts, so the river helps most. A: The blotch between the eyes ends in three forward prongs and rarely joins those behind the eyes in the Escambia Map Turtle; the blotch between the eyes tapers to a point over the nose and usually joins those behind in the Barbour's Map Turtle. B: A single straight yellow bar on each edge plate in the Escambia Map Turtle; a curved yellow bar on each edge plate in the Barbour's Map Turtle. Barbour's has a light bar across or along the curve of the chin; the Escambia has spots on the sides of the chin.
