Turtles and tortoises are inquisitive creatures, but they do not possess a great deal of what you would call "knowledge." Some turtles have better awareness of their surroundings (such as height or motion) than others, even within the same species. All turtles fail sentience tests, as they cannot distinguish between a reflection of themselves and another turtle. Red-eared sliders are no exception.
