Description
Size
2.5 - 10 inches in shell length (6.3 - 25.4 cm). (Stebbins 2003)
Appearance
A small turtle with red markings on the marginals and a smooth, oval, somewhat flattened, keelless carapace which is black, brown, or olive in color with a network of faint light lines and olive, yellowish, or red borders along front edge of the shields. The posterior rim of the carapace has a smooth (not serrated) border. The limbs and head are black to olive and marked with yellow lines. Yellow stripes extend rearward from underneath the eyes and often from below the jaw. The upper jaw is notched in front. The unhinged plastron is reddish with a large dark mark in the center which branches out between the scutes.

Males are smaller than females and have very long nails on the front feet. The plastron coloring on juveniles is more strongly contrasted than on adults.
Behavior and Natural History
Aquatic and diurnal. Sleeps at night on the bottom or on a partially submerged object. Probably active all year long in the south but inactive during cold periods. In the north, probably hibernates beginning in late fall, emerging in March or April.
Often seen basking on rocks, logs, or dirt banks, sometimes in large groups.
Relatively cold-tolerant. In some areas, they can be observed swimming under ice just before it melts in March.
Diet
An omnivorous generalist - eating almost anything found in its habitat, including insects, worms, snails, crayfish, fish, amphibians and tadpoles, carrion, and aquatic vegetation. Young are carnivorous, but become more herbivorous as they grow older.
Reproduction
Becomes sexually mature when it reaches the appropriate size, typically in 3 - 6 years. Breeds from March to June. Females dig a nest at a sunny site near water in loose soil between May and August, and lay from 1 - 4 clutches of 1 - 25 eggs.
Range
Introduced and established throughout coastal southern California, in Santa Barbara County, and in the kaiser Meadow area of Siskiyou County.

The most widespread species of turtle in North America, ranging across the entire continent from southeastern Canada to Louisiana to Washington, with isolated populations in Utah, Arizona, New Mexico and Texas.
Habitat
Ponds, marshes, lakes, ditches, quiet streams with sandy or muddy bottoms and aquatic vegetation.
Taxonomic Notes
Four subspecies are traditionally recognized.

In 2003, Starkey, David E., H. Bradley Shaffer, Russell L. Burke, Michael R. J. Forstner, John B. Iverson, Fredric J. Janzen, Anders G. J. Rhodin, and Gordon R. Ultsch [Molecular systematics, phylogeography, and the effects of Pleistocene glaciation in the Painted Turtle (Chrysemys picta) complex. Evolution 57(1): 119-128] determined that Chrysemys picta consists of two species. If this is accepted, C. p. bellii will become Chrysemys picta with no subspecies recognized.
Conservation Issues  (Conservation Status)
Being an introduced species, it is possible that this turtle competes with and therefore poses a threat to native Pond Turtles.
