Description: Adult painted turtles can grow to 5 to 10 iches long, with males being smaller. The shell is oval, smooth with little grooves where the large scale-like plates overlap, and flat-bottomed. The color of the top shell (carapace) varies from olive to black. Darker specimens are more common where the bottom of the water body is darker. The bottom shell (plastron) is yellow, sometimes red, sometimes with dark markings in the center. Similar to the top shell, the turtle's skin is olive to black, but with red and yellow stripes on its neck, legs, and tail. As with other pond turtles, such as the bog turtle, the painted turtle's feet are webbed to aid swimming.

The head of the turtle is distinctive. The face has only yellow stripes, with a large yellow spot and streak behind each eye, and on the chin two wide yellow stripes that meet at the tip of the jaw. The turtle's upper jaw is shaped into an inverted "V" (philtrum), with a downward-facing, tooth-like projection on each side.

The hatchling has a proportionally larger head, eyes, and tail, and a more circular shell than the adult. The adult female is generally longer than the male, 4 to 10 inches versus 3 to 6 inches. For a given length, the female has a higher (more rounded, less flat) top shell. The female weighs around 18 ounces on average, against the males' average adult weight of roughly 11 ounces). The female's greater body volume supports her egg-production. The male has longer foreclaws and a longer, thicker tail, with the anus (cloaca) located further out on the tail.

Habitat: Painted turtles prefer living in freshwater that is quiet, shallow, and has a thick layer of mud.

Range: The most widespread North American turtle, the painted turtle is the only turtle whose native range extends from the Atlantic to the Pacific. It is native to eight of Canada's ten provinces, forty-five of the fifty United States, and one of Mexico's thirty one states. On the East Coast, it lives from the Canadian Maritimes to the U.S. state of Georgia. On the West Coast, it lives in British Columbia, Washington, and Oregon and offshore on southeast Vancouver Island. The northernmost American turtle, its range includes much of southern Canada. To the south, its range reaches the U.S. Gulf Coast in Louisiana and Alabama. In the southwestern United States there are only dispersed populations. It is found in one river in extreme northern Mexico. It is absent in a part of southwestern Virginia and the adjacent states as well as in north-central Alabama.

Diet: The western painted turtle's consumption of plants and animals changes seasonally. In early summer, 60% of its diet comprises insects. In late summer, 55% includes plants. Of note, the western painted turtle aids in the dispersal of white water-lily seeds. The turtle consumes the hard-coated seeds, which remain viable after passing through the turtle, and disperses them through its feces.

Reproduction: The painted turtles mate in spring and fall in waters of 50 tbo 77℉. Males start producing sperm in early spring, when they can bask to an internal temperature of 63℉. Females begin their reproductive cycles in mid-summer, and ovulate the following spring.

Courtship begins when a male follows a female until he meets her face-to-face. He then strokes her face and neck with his elongated front claws, a gesture returned by a receptive female. The pair repeat the process several times, with the male retreating from and then returning to the female until she swims to the bottom, where they copulate. As the male is smaller than the female, he is not dominant. Although not directly observed, evidence indicates that the male will inflict injury on the female in attempts of coercion. Males will use their tooth-like cusps on their beaks and their foreclaws during this act of coercion with the female. The female stores sperm, to be used for up to three clutches, in her oviducts; the sperm may remain viable for up to three years. A single clutch may have multiple fathers.

Nesting is done, by the females only, between late May and mid-July. The nests are vase-shaped and are usually dug in sandy soil, often at sites with southern exposures. Nests are often within 220 yards of water, but may be as far away as 660 yards, with older females tending to nest further inland. Nest sizes vary depending on female sizes and locations but are about 2 to 4 inches deep. Females may return to the same sites several consecutive years, but if several females make their nests close together, the eggs become more vulnerable to predators. Female eastern painted turtles have been shown to nest together, possibly even participating in communal nesting.

The female's optimal body temperature while digging her nest is 84 to 86℉. If the weather is unsuitable, for instance a too hot night in the Southeast, she delays the process until later at night. Painted turtles in Virginia have been observed waiting three weeks to nest because of a hot drought.

While preparing to dig her nest, the female sometimes exhibits a mysterious preliminary behavior. She presses her throat against the ground of different potential sites, perhaps sensing moisture, warmth, texture, or smell, although her exact motivation is unknown. She may further temporize by excavating several false nests as the wood turtles also do.

The female relies on her hind feet for digging. She may accumulate so much sand and mud on her feet that her mobility is reduced, making her vulnerable to predators. To lighten her labors, she lubricates the area with her bladder water. Once the nest is complete, the female deposits into the hole. The freshly laid eggs are white, elliptical, porous, and flexible. From start to finish, the female's work may take four hours. Sometimes she remains on land overnight afterwards, before returning to her home water.

Females can lay five clutches per year, but two is a normal average after including the 30 to 50% of a population's females that do not produce any clutches in a given year. In some northern populations, no females lay more than one clutch per year. Bigger females tend to lay bigger eggs and more eggs per clutch. Clutch sizes of the subspecies vary, although the differences may reflect different environments, rather than different genetics. The two more northerly subspecies, western and midland, are larger and have more eggs per clutch, 11.9 and 7.6, respectively, than the eastern (4.9). Within subspecies, also, the more northerly females lay larger clutches.

Status: The species is currently classified as least concern by the IUCN but populations have been subject to decline locally. The decline in painted turtle populations is not a simple matter of dramatic range reduction, like that of the American bison. Instead the turtle is classified as G5 (demonstrably widespread) in its Natural Heritage Global Rank, and the IUCN rates it as a species of least concern. The painted turtle's high reproduction rate and its ability to survive in polluted wetlands and artificially made ponds have allowed it to maintain its range, but the post-Columbus settlement of North America has reduced its numbers.

Subspecies: Three, all found in the United States:
   Western Painted Turtle (Chrysemys picta bellii)
   Midland Painted Turtle (Chrysemys picta marginata)
   Eastern Painted Turtle (Chrysemys picta picta)
