Smooth softshell turtles are medium-sized freshwater turtles, with their size varying significantly between males and females. Females are notably larger than males, making them one of the more distinctively sized turtle species by sex.
Understanding Smooth Softshell Turtle Size
Unlike most turtles that possess hard, bony shells, smooth softshell turtles are characterized by their smooth, leatherlike, flexible carapace and a long, tubular snout. Their size is primarily measured by the length of this unique carapace.
Carapace Length by Sex
The size difference between male and female smooth softshell turtles is quite pronounced. This sexual dimorphism is a key characteristic when identifying or studying the species.
Here's a breakdown of their typical carapace lengths:
| Sex | Carapace Length (cm) | Carapace Length (in) |
|---|---|---|
| Female | 16.5 – 35.6 cm | 6.5 – 14 in |
| Male | 11.4 – 17.8 cm | 4.5 – 7 in |
As seen in the table, a large female smooth softshell turtle can be more than double the size of a large male, showcasing a clear distinction in their physical dimensions. This size disparity often plays a role in their reproductive strategies and ecological roles within their habitats.
