Pond slider

Trachemys scripta, better known as the pond slider, is a common, medium-sized semi-aquatic turtle. There are three subspecies of sliders.[2] The most recognizable subspecies is the red-eared slider (T. s. elegans), which is popular in the pet trade. This subspecies has been introduced to other parts of the world by people releasing it to the wild. Slider hatchlings have a green shell (carapace) and skin with yellow green and dark green striped markings. Markings and colors fade in adults to a muted olive green color. Some individuals become almost black with few visible markings. The carapace is oval and flattened. The underside of the shell is yellow with dark markings in the center of each scute.
