such as a lack of scales, lack of pigmentation and reduced eyes (some are completely blind). Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back (above the forehead), the function of which is unclear. In contrast, the ''Sinocyclocheilus'' species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as
