Southern painted turtle (C. p. dorsalis)
A variant of Painted turtle (Chrysemys picta)

Representative Painted turtlephoto — a dedicated image of this exact morph isn't available yet.
The smallest, most distinctive subspecies with a bold orange-to-red dorsal stripe running the length of the carapace. A trade favorite for that vivid stripe.
Keeper tips for this variant
Stays under 6 inches, so a 40-gallon footprint suits a single adult; keep water warm (75-80F) as it is the most heat-loving painted turtle.
