>The turtle penis is, like that of a mammal, a hydraulic cylinder that becomes engorged by fluid and is relatively resistant to bending when erect. Its single erectile body is divided into a collagenous corpus fibrosum and a highly vascularized, expandable corpus spongiosum. As a turtle’s penis inflates, its length may increase by nearly 50%, its width by 75%, and its depth by 10%. Even an uninflated penis – tucked away inside the cloaca – is large. More on the issue of size later on.
