The Painted Turtle derives its common name from the colorful markings adorning its shell, skin, and limbs, creating an appearance reminiscent of decorative painting. The vibrant red, yellow, and orange stripes on the neck, legs, and tail, combined with the colorful marginal scutes edging the carapace, make these turtles among the most visually striking North American species. The name "Painted Turtle" is universally recognized and aptly describes the species' most appealing characteristic. This single species encompasses considerable geographic variation, leading to recognition of four subspecies based on range and pattern differences.
The four recognized subspecies include the Eastern Painted Turtle (Chrysemys picta picta), Southern Painted Turtle (C. p. dorsalis), Midland Painted Turtle (C. p. marginata), and Western Painted Turtle (C. p. bellii). Each subspecies shows distinctive pattern characteristics though all share the basic colorful painted appearance. The Eastern Painted Turtle displays relatively aligned scutes on the carapace with a plain or lightly marked plastron. The Southern Painted Turtle features a prominent red or orange stripe down the center of the carapace. The Midland Painted Turtle shows a dark central figure on the plastron. The Western Painted Turtle is the largest subspecies with netted pattern on the carapace. Intergrades occur where subspecies ranges overlap, showing intermediate characteristics.
Alternate common names are limited given the species' widespread recognition. Regional names may reference specific subspecies such as "Eastern Painted," "Southern Painted," or "Western Painted." The terms "pond turtle" or "pond slider" are occasionally used regionally though these are less specific and can apply to other species. In scientific and conservation literature, the full name Painted Turtle with subspecies designation when relevant is standard. Historical names from early natural history texts are now obsolete. The species is so well-known throughout its range that the simple name "Painted Turtle" is rarely confused with other species.
Scientifically, Painted Turtles belong to the genus Chrysemys, family Emydidae, which includes numerous North American pond and marsh turtles. The genus name Chrysemys is derived from Greek words meaning "gold turtle," likely referencing the yellow striping on the head and limbs. The specific epithet "picta" is Latin meaning "painted," directly describing the colorful markings. The species was described scientifically by Schneider in 1783, relatively early in North American herpetological taxonomy. The genus Chrysemys historically included several species but has been revised over time, with Painted Turtle now the primary species though some taxonomists debate whether certain populations warrant recognition as distinct species.
