Male Slider turtles have usually big penises compared to small mammals of the same size

The claim that male slider turtles have larger penises compared to small mammals of the same size is a nuanced assertion that requires careful consideration. While there is evidence suggesting that male turtles, including slider turtles, possess relatively large reproductive organs in comparison to their body size, the claim lacks robust scientific backing and comparative studies directly addressing the size of turtle penises relative to those of small mammals. The sources reviewed predominantly come from forums and non-peer-reviewed articles, which diminishes their reliability. Some sources mention the size of turtle penises as being significant among reptiles, but they do not provide a clear comparative analysis with small mammals. Therefore, while there is a basis for the claim regarding the size of male slider turtles' reproductive organs, the lack of rigorous scientific evidence makes it difficult to fully endorse the assertion.
