The yellow-bellied slider (''Trachemys scripta scripta'') is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia,〔Conant, R., J. Collins. 1991. ''Peterson Field Guides: Reptiles and Amphibians of Eastern/Central North America.'' Boston: Houghton Mifflin Co.〕 and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds.〔(【引用サイトリンク】 title=Yellow-Bellied Slider reptiles )〕 Yellow-bellied sliders are popular as pets. ==Description== Adult male yellow-bellied sliders typically reach in length; females range from .〔(【引用サイトリンク】 title=Care Sheet — Yellow-bellied Slider )〕 The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adult males tend to grow darker as they age.〔(【引用サイトリンク】 title=Yellow-bellied Slider Turtle )〕〔(【引用サイトリンク】 title=Choosing a Yellow-Bellied Slider )〕 Yellow-bellied sliders are often confused with Eastern River Cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of ''T. scripta scripta.'' The yellow belly often has an "s"-shaped yellow stripe on its face. Mating can occur in spring, summer, and autumn. Yellow-bellied sliders are capable of interbreeding with other ''T. scripta'' subspecies, such as red-eared sliders, which are commonly sold as pets. The release of non-native red-eared sliders into local environments caused the state of Florida to ban the sale of red-eared sliders in order to protect the native population of yellow-bellied sliders. Mating takes place in the water. Suitable terrestrial area is required for egg-laying by nesting females, who will normally lay 6–10 eggs at a time, with larger females capable of bearing more. The eggs incubate for 2–3 months and the hatchlings will usually stay with the nest through winter. Hatchlings are almost entirely carnivorous, feeding on insects, spiders, crustaceans, tadpoles, fish, and carrion. As they age, adults eat less and less meat, and up to 95% of their nutritional intake eventually comes from plants.〔 The slider is considered a diurnal turtle; it feeds mainly in the morning and frequently basks on shore, on logs, or while floating, during the rest of the day. At night, it sleeps on the bottom or on the surface near brush piles. Highest densities of sliders occur where algae blooms and aquatic macrophytes are abundant and are of the type that form dense mats at the surface, such as ''Myriophyllum spicatum'' and lily pads (Nymphaeaceae). Dense surface vegetation provides cover from predators and supports high densities of aquatic invertebrates and small vertebrates, which offer better foraging than open water. The lifespan of yellow-bellied sliders is over 30 years in the wild,〔(【引用サイトリンク】 title=Yellow-bellied Slider )〕 and over 40 years in captivity.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Yellow-bellied slider」の詳細全文を読む スポンサード リンク
