All three historically recognized subspecies (K. s. subrubrum, K. s. steindachneri, and K. s. hippocrepis) are semi-aquatic turtles that inhabit much of the U.S. Atlantic and Gulf Coastal Plains. The Florida taxon (K. s. steindachneri) appears to represent a distinct species, but we continue to treat it as a subspecies for the purposes of this account.
