The red belly turtles in south jersey are northern red bellies (Pseudemys rubriventris). There are three subspecies of the red belly that are recognized with each separated geographically along the east coast from Massachusetts to Alabama. The Texas river cooter (Pseudemys texana) is sometimes added to the group but is found only in central and eastern Texas. Other than the notching and cusping of the upper jaw, it has little resemblance to the northern red bellies and instead looks much like a form of the river cooter, which it was long associated with. The northern belly's range is from southern New Jersey south to northeastern North Carolina. There is isolated northern red bellies in southeastern Massachusetts and has long been distinguished as a separate subspecies (Pseudemys rubriventris bangsi) but repeated studies have failed to find any characters to distinguish it from its southerly members of the same species. The northern red belly as (5) yellow lines on the face and as they grow older they become melanistic or get darker which obscures the lines on the face. The Florida red belly (Pseudemys nelsoni) is a southern form of Pseudemys rubriventris, differing mostly in having a brighter color and less dark patterning on the plastron of juveniles. The yellow stripes on the head are reduced in number (3) and sometimes partially fused. Lastly, the Alabama red belly (Pseudemys alabamensis). This subspecies is restricted to the rivers and streams around Mobile Bay in southern Alabama. The only reason this form of red belly is considered a distinct subspecies is because it presently does not come into contact with the Florida red belly. There is fossil evidence to show that the Florida red belly's range once extended north to South Carolina, and the recent discovery of an apparently undescribed red belly turtle to the north west of the range of the Alabama red belly ties in well with the idea that the red bellies all are part of what was one continuous species.
