The karst landforms of China are renowned around the world for the beauty of their landscapes, but it is less well appreciated that they also contain extensive cave systems with very significant underwater habitats. China also has an extremely high level of biodiversity, including over 1,500 freshwater fish species. Unsurprisingly, some of these species inhabit the karst cave systems and have flourished and diversified under unique environmental conditions. As a result, cave fishes in China are particularly abundant and diverse when compared to those of other countries of the world. These remarkable fishes have received considerable research attention from Chinese ichthyologists and, for the first time, this book makes their resulting findings directly accessible to the English-speaking world through a remarkable endeavour of Sino-British collaboration.
