洞鲈 【dòng lú】

洞鲈生活在北美洲中部和东部相当黑暗的洞窟内的地下水中。眼睛退化无视力，但依其极为发达的侧线和头部感觉器官，可以感觉到空气或水流极为微小的震动。

The cave perch lives in the underground water in rather dark caves in central and eastern North America. The eyes degenerate and have no vision, but according to its highly developed lateral lines and head sensory organs, they can feel the extremely small vibration of air or water flow.
