Typhlobarbus nudiventris

Small, slender, with flat chest and abdomen, gradually flattened towards the back. Medium-sized head. Blunt snout, slightly protruding. The anterior nostril has a short tube, separated from the posterior nostril by a nasal valve. The eye socket is located in the center of the head, slightly concave, filled with fat tissue, or with only a pinpoint-shaped hole, with a black bottom, where the extremely degraded eyeball is located. The mouth is sub-inferior, arc-shaped, with a small protrusion in the center of the lower jaw, and no notch in the upper jaw. There is a pair of snout and mandibular barbels, about the same length. The scales are medium-sized, naked in the center of the front back and the chest and abdomen. There are 39 to 40 lateral line scales. The dorsal fin has no hard spines, and the starting point is in front and above the starting point of the pelvic fin; the pectoral and pelvic fins are flat and on the same plane as the chest and abdomen; the pectoral, pelvic and anal fi

Yangjieba is a famous dry dam in Jianshui County. Most of it is composed of basalt, and the surface water retention performance is very poor. After rain, runoff seeps into the ground through the cracks in the rocks and converges in the cave, so the underground water source is abundant. The cave where the naked abalone lives was originally connected to the ground by a crack in the rock. The place is 1,450 meters above sea level and is located on a hillside. In order to utilize the underground water source, Yangjieba Farm dug a tunnel obliquely to the cave, equipped with a pump to facilitate irrigation. The water in the cave flows slightly, and the surroundings are dark and lightless. The water surface is 100 meters vertically away from the ground surface.

The Latin name of naked blind barb is Typhlobarbus nudiventris, a fish of the genus Typhlobarbus in the family Cyprinidae.

The number of naked blind barb is extremely rare. The two specimens obtained later were kept in a ceramic water tank for several days. When at rest, it supports its body with the outer edge of the pectoral and pelvic fins and the tip of the lower lobe of the caudal fin, lying with its head raised, its snout facing the side and front, its nostrils open, and its nasal valves erected; when swimming, it always stays close to the wall of the tank, rarely in the middle of the container, sometimes it jumps up continuously along the wall of the tank, half of its body is exposed above the water, and its head, chest and abdomen are flat against the wall of the tank, and it slides into the water in a moment, swims several circles, and then returns to rest. It is quite sensitive to sudden vibrations, such as tapping the container, and it immediately moves away from the wall of the tank, fleeing east and west, and is very panic. Fecal examination found the shell of tin insects. It is speculated that it mainly feeds on bat feces.

The fish discovered in 1978 and reported as scientific news was the first blind fish discovered in my country. It clearly answered the question of whether there are blind fish in China. It caused widespread repercussions at the time, setting off a wave of searching for and studying blind fish, and since then, the research on cave fish and cave biology in my country has begun. Although the process of this research has become history, the scientific value of the blind abalone itself remains.

Due to the large amount of water extraction, the habitat of the blind gills has been destroyed, and even the basic conditions for survival have been lost.

It was listed in the list of rare protected animals in Yunnan Province in 1989, and listed in the Red Book of Endangered Animals in China in 1998, but there is no specific protection action.

It is listed in the second level of the "List of National Key Protected Wildlife in China".

Protect wild animals and eliminate game.
