Alamo Mud Turtle
The Alamo Mud Turtle was discovered by Berry and Legler. Named in 1980, the average size is 13.5 cm. The carapace is relatively flat and narrow, oval in shape, and there is no protruding vertebral keel on the back.
The edges of the Alamo mud turtle's scute are folded into tiles on all sides. The first vertebral scute is not as long as the second marginal scute, and the 10th and 11th vertebral scutes. The edge shield is lower than the remaining pieces. The posterior round edge of the carapace is relatively straight, but there is almost no mid-dorsal or medial dorsal curvature. The colors are usually tan, brown and olive, with black seams between the shields. Through the translucent shield, you can often see the joints of the lower bones.

If there is a flaw, it is limited to a shallow groove at the end of the anal shield. The order of displaying the size of the dorsal shield is: dorsal shield>anal shield>throat shield>rib shield>hip shield>chest shield. The carapace is slightly yellow, and there are brown intersecting lines and growth lines between the scutes.
The nail bridge is relatively small, about 26~33% of the length of the carapace. The axillary scutes are widely separated from the dorsal inguinal scutes, and then The person is the same as the 6th pair of shield soldiers. The broad head has a short snout and a hook-shaped upper jaw without an obvious upper jaw. The rostrum is neither prominent nor exhibits a V-shaped shape. There are two yellow tentacles on the chin, a gray head with black circles, and patterns on both sides of the head. A pale stripe extends from the eye socket to the corner of the mouth. The curved jaw is usually cream or gray-white, and males have hazy, brown patterns here. The back and bottom of the neck are gray and yellow respectively. There is a scale-like joint on the surface of the thighs and hind legs, and there are spines at the end of the tail.
The male is slightly larger than the female, but narrower than the female. There is a prominent carapace and a long and thick tail. The female's carapace is flatter or slightly more prominent and the tail is shorter.
