A red-eared slider turtle is observed basking on a dark gray, elevated platform within a glass aquarium, situated in Aldoar, Foz do Douro e Nevogilde, Portugal. The turtle, positioned facing left with its head slightly raised, exhibits a dark, somewhat textured carapace with faint reddish-orange longitudinal stripes. Its head and neck display yellow-green markings, highlighted by distinct red patches located behind each eye. The platform is a flat, rectangular slab, supported by a structure partially submerged in the aquarium's lower section, which contains murky, greenish-brown water. A black, ribbed plastic ramp is partially visible on the right side of the frame, extending into the water. The immediate background behind the tank consists of a light-colored brick or tiled wall. Strong, directional sunlight illuminates the scene, casting prominent, angular shadows of unseen structures onto the wall and the basking platform.
