Alabama Red-bellied Turtle
This large basking turtle is centered in the lower Mobile–Tensaw system, where freshwater marsh, submerged vegetation, and nesting ground meet tidal influence.

Adults carry a dark shell with reddish or orange marks and fine yellow head stripes, but identification is difficult beside related cooters. The species feeds heavily on aquatic plants and depends on sunny logs or banks for thermoregulation.
Roads, shoreline development, boat strikes, nest predators, and collection pressure squeeze a narrow range. Watch with binoculars from public access and let experts distinguish it; never pull a basking turtle from a log for confirmation.
