The '''Cumberland slider''' ('''''Trachemys scripta troostii''')'', also called commonly the '''Cumberland turtle''' and '''Troost's turtle''', is a subspecies of pond slider, a semiaquatic turtle in the family Emydidae. The subspecies is indigenous to the Southeastern United States.
==Etymology== The subspecific name, ''troostii'', is in honor of Dutch-American naturalist Gerard Troost.<ref>Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. {{ISBN|978-1-4214-0135-5}}. (''Trachemys scripta troostii'', p. 268).</ref>
==Taxonomy== ''T. s. troostii'', a subspecies of ''T. scripta'', was formerly placed in the genus ''Pseudemys''. The Cumberland slider occurs in a different geographic location from the yellow-bellied slider (''T. s. scripta''). Intergradation does not occur between these two subspecies.{{cn|date=March 2024}}
==Description== The carapace of ''T. s. troostii'' is olive brown with yellow markings. It has two rounded projections on the posterior edge of the shell, and is slightly keeled. The adult carapace is wrinkled and oval shaped. The plastron is hingeless and slightly smaller than the carapace. Each of the bottom sides of the marginals has a spot. The skin is brown with an olive to greenish tint with yellow striping. There is a distinct bar behind the eyes that can vary from yellow to red and be either thin or wide. The plastron of the turtle has dark spots, as well as the ridge of the carapace. Also, the plastron has yellow bars or stripes. The turtle's legs in front have larger yellow stripes than most slider species. There is a yellow and orange stripe directly behind each eye. The stripe is never entirely one color, it starts out yellow and then fades into a dark orange-to-red color closer to the back of the neck.{{cn|date=March 2024}}
==Behavior== ''T. s. troostii'' is a communal basker. It basks on protrusions out of the water and may bask in stacks or with other species. It is active from April to October. "Slider" comes from its habit of sliding into the water when alarmed while basking, going to deep water for safety, where most predators cannot pursue it.{{cn|date=March 2024}}
==Geographic range and habitat== ''T. s. troostii'' is found throughout the Mississippi and Tennessee River drainages, and the Southeastern United States. This subspecies prefers quiet waters with muddy bottoms. Ponds, lakes, and streams, with a profusion of aquatic vegetation, organic substrate, and overhanging basking spots, are especially favored.{{cn|date=March 2024}}
Most people agree that the native lands of the Cumberland slider are in the Cumberland River Valley, ranging in Kentucky and Tennessee, but with the exotic animal trade, it has become a common sight even in Alabama, Georgia, and Illinois.<ref>{{cite web |url=http://www.ben.edu/museum/cumberlandslider.asp |title=Cumberland Slider (Troosts Turtle) |accessdate=2009-06-26 |url-status=dead |archiveurl=https://web.archive.org/web/20081027224109/http://www.ben.edu/museum/cumberlandslider.asp |archivedate=2008-10-27 }}</ref>
==Reproduction== Breeding of ''T. s. troostii'' takes place in spring, fall, and winter. The male and female go through a mating ritual in which the male "claws" at the female's face and his fore legs stiffen. The female then allows the male to mount. The females may go extremely far from the water to nest and are occasionally hit by cars while crossing roads. Females construct a nest, usually at night, in various soil types. Clutch size is six to 15 eggs with 71% of the females producing two clutches per year.{{cn|date=March 2024}}
==Diet== ''T. s. troostii'' is mostly herbivorous as an adult, but primarily carnivorous as a juvenile.<ref>Clark, David B.; Gibbons, J. Whitfield (1969). "Dietary Shift in the Turtle ''Pseudemys scripta'' (Schoeppf) from Youth to Maturity". ''Copeia'' '''1969''' (4): 704–706.</ref> The adults eat algae, fish, tadpoles, crayfish, seeds, plants, aquatic vegetation, insects, worms, and mollusks.{{cn|date=March 2024}} This subspecies, like all aquatic turtles, can only swallow food when in the water.{{cn|date=March 2024}}
<!-- not encyclopedic how-to ==Care== Although ''T. s. troostii'' is common in pet stores, it requires attention and care to keep the turtle healthy. The minimum recommended size aquarium for an adult is a 120 × 40 × 60 cm (48 × 15 × 23 in) 55 gallon (208 litre) tank, with a water level of at least 40 cm (15 in). The difference between air and water temperature must not exceed 5 degrees in both directions. -->
