Anatomy and morphology
A megacephalic form of the red-necked pond turtle exists, commonly called 'dumb-head'. This form is rarer than the smaller headed individuals.[4] This species has strong sexual dimorphism with a significant size difference between males and females. The largest recorded male's carapace measured 185mm (7.2 in) in length whereas females with a size up to 298 mm (11.7 in) have been found.[6]
