Distinguishing Features:
Eastern populations of yellow-bellied sliders possess a recognizable yellow spot behind their eyes,a key field identification characteristic. Juvenile turtles sport vibrant yellow markings, while vertical yellow bands grace their carapace.This species separates itself with its adjusted lower jaw, separating it from different turtles that have level jaws.Furthermore,yellow-bellied sliders will quite often have a more articulated domed shape contrasted with cooters.Their size can vary, with carapace lengths ranging from 5 to 12 inches.
Habitat & Behavior:
These turtles are predominantly found near water bodies and are often seen basking on shores, fallen trees, or rock piles.They are truly aquatic, displaying both terrestrial and aquatic characteristics.Equipped with long claws for crawling on land and webbed toes for efficient swimming,they are well-suited for their semi-aquatic lifestyle.
Care & Diet:
In captivity, yellow-bellied sliders thrive in shallow water aquarium setups with basking sites that allow them to fully emerge from the water.A basking light maintaining a temperature of around 80 degrees Fahrenheit is essential. Providing a basking platform made of plastic grating or egg crate material is ideal, as it won't harm the turtle's plastron. This setup helps prevent shell fungus and rot.Yellow-bellied sliders are omnivorous, with juveniles being more carnivorous than adults.They consume aquatic insects like dragonfly larvae, crayfish, snails, as well as turtle pellets, chopped meat, lettuce, and fruits.
These turtles are known for their longevity,with individuals captured in the late 1960s and 1970s still being recaptured today.Their enduring presence makes them a captivating and enduring species in the world of turtles.
Distribution and Geographic Variation:
Yellow-bellied sliders, scientifically known as Trachemys scripta scripta, have a distinct distribution range spanning from southeastern Virginia through the coastal plains of the Carolinas, Georgia, northern Florida, and eastern Alabama. However, their presence in European countries, where they've become established and invasive, raises concerns about potential threats to native biodiversity due to their competitive advantage over native terrapins.
Geographic Variation in Body Size:
The size of these turtles can vary significantly among populations. Adult females in different regions exhibit variations in carapace length (CL). For example, in the Dismal Swamp National Wildlife Refuge, the average CL for adult females is approximately 251.6 ± 23.3 mm, whereas in Back Bay National Wildlife Refuge and False Cape State Park, it's around 246.8 ± 13.8 mm. In Game Refuge Lake, Sussex County, adult females have an average CL of about 199.9 ± 22.8 mm. Notably, the largest known slider in Virginia measured 309 mm CL and was identified as a female from the Dismal Swamp.
Geographic Variation in Pattern:
Geographic variation in pattern is observed in two distinct ways. Firstly, it occurs within the two subspecies naturally found in Virginia, which are elaborated upon in the "Description" section. Secondly, it arises through intergradation with the introduced subspecies Trachemys scripta elegans in southeastern Virginia. These intergrades are the result of juveniles of the Red-Eared Slider (T. s. elegans) being sold in pet stores throughout the United States before 1972. Many of these turtles were subsequently released into local waters, leading to the establishment of numerous populations in Virginia, particularly in urban areas.
Turtles in populations with intergrades exhibit characteristics typical of both natural T. s. scripta and introduced T. s. elegans. Red-Eared Sliders, for instance, are distinguished by enlarged reddish patches behind each eye, narrow chin stripes, a yellowish-green carapace with distinct yellow streaks on the pleural scutes, black blotches on most of the plastral scutes, and horizontal yellow and black stripes on the rear of the thighs. Intergrades may display the reddish (or yellowish) patches behind the eyes or have both the red streak and a reduced, vertical yellow bar. They also exhibit black blotches of varying sizes on several plastral scutes and a mottled pattern or set of horizontal lines on the rear of the thighs. The carapace typically appears greenish with a narrow yellow line in each of the pleural scutes.
The presence of intergrades underscores the complex genetic interactions between these subspecies, with potential implications for their conservation and management.
