| Abstract: | This article described the morphological characteristics, discussed the adaptive traits on eight species of Sinocyclocheilus collected in Libo county of Guizhou province, and found some representative adaptive characteristics to the underground environment such as vestigial eyes, sense tubes derived from lateral line and head, width of pectoral fins and length of barbels, and special protuberance on head or back. It suggested that all eight species belonged to the atypical cave species, and showed the transitional distribution in the underground water. |
