1. Surface characteristics of the Gepidia mud turtle
Oval The carapace is slightly flat, the color is mostly brown, and the body length can reach 17.5 cm. There is no protruding vertebral keel in the center of the carapace of adults. Differently, in larvae, there are three longitudinal and relatively hazy vertebral keels.
The scute is slightly overlapping, and the shell is interrupted at the bridge of the plastron. The tiny plastron has a hinge cover at the front and back, and the end piece at the back has a groove. The width separation between the front hinge cover and the rear hinge cover of the plastron is less than 40% and 35% of the maximum length of the carapace. The length of the armor bridge is 21% to 26% of the maximum length of the carapace, and the axillary scutes and inguinal scutes meet.
The plastron and nail bridge are often yellow with black intersecting lines. The head is relatively broad, with a long mouth and nose, the upper jaw is excessively hook-shaped, and the chin has four tentacles. The top of the head is brown, and the sides and bottom are relatively bright in color (there may be some color spots or patterns). The neck, hands, feet and tail are light gray.
Second, the gender difference between brother and Asian mud turtles
Brother The neck, hands, feet, and tail of the Piedmont mud turtle are light gray. Males have horny appendages on their thighs and lower limbs, and both males and females have horn-like spines at the end of their tails. In addition, we can distinguish between males and females by checking whether there are scale-shaped horny threads on the inside of the hind legs. The male is larger and has a long and thick tail; while the female is usually about 15 centimeters long and has a shorter tail.
