New discovery of cave blind fish in wuming , Guangxi

已有的研究认为盲鱼是美国于1842年率先报道的，在136年之后中国才首次发现了盲鱼。

Some people held that the blind fish was first discovered in America in 1842 , and that it was found in China 136 years afterwards .

正常鱼原始鱼体方向反向时对运动纲索的转向率显著地大于同向时的转向率，但盲鱼转向率在原始鱼体方向间差异不显著。

The original body direction of the normal fish has evident effect on its direction changing and rope-passing rates .

实际上，至迟在1839年，清代博物学家郑光祖在《一斑录》中，不仅早已记载了盲鱼，而且敏锐地认识到盲鱼是生物本身适应环境的自然演进。

In fact , in1839at the latest the Qing naturalist Zheng Guangzu in his Yi Ban Lu had reported the fish and keenly recognized that it was the outcome of natural evolution of living things to adapt themselves to circumstances .
