Key Characters: Relatively low, smooth-edged shell; red markings on marginals or plastron; upper jaw with median notch bordered by toothlike cusps.

Similar Species: Slider (melanistic males).

Subspecies: Western painted turtle, C. p. bellii; midland painted turtle, C. p. marginata; and intergradation between midland and southern painted turtle, C. p. dorsalis.

Description: Medium-sized (up to 18 cm CL) turtle with yellow stripes on head and olive to black carapace. Marginal scutes with vertical bars (bellii) or horizontal to curved markings (marginata); red midback stripe broad (dorsalis), narrow (marginata), or absent (bellii). Plastron: yellow, red, or orange; dark markings broad, laterally branching, and covering most of plastron (bellii); elongated and confined to midplastral seam (marginata); or absent (dorsalis). Extensive intergradation among subspecies produces great variation within state.

Habitat: Frequents most aquatic habitats but most common in shallow, quiet, weedy parts of lakes, ponds, marshes, and river backwaters.

Natural History: Basking congregations are common on logs and banks. Omnivorous diet includes plants, insects, and mollusks. Readily scavenges on dead fish. Nests May to July. Lays 2-3 clutches of 8-9 flexible-shelled, ellipsoidal eggs (ca. 32 x 20 mm). Hatchlings usually overwinter in nest.

Status: Highly adaptable, less susceptible to habitat modification than many turtles. Some collected illegally as pets, but no population appears seriously reduced. Common and widespread.
