Red-eared sliders are a turtle native to the south eastern United States, this photo was taken in south Texas. They are mostly aquatic coming out usually only to sun bathe or lay eggs. Red-eared sliders are the most popular pet turtles in the United States. Released pets have established populations outside of their normal range and have even become invasive in some areas, such as parts of California where they are able to out compete the native western pond turtle. Like most turtles red-eared sliders are omnivores. Their diet consists of fish, frogs, crustaceans, aquatic insects and aquatic plants.
