Jullien's golden carp

Jullien's golden carp is a critically endangered species of freshwater ray finned fish in the family Cyprinidae, found in Southeast Asian river basins including the Mekong, Irrawaddy, Chao Phraya, Meklong, Pahang and Perak, though it now survives mainly in the Mekong. It can reach about 165 centimeters in length and 70 kilograms in weight, and can live up to 50 years; it shows five longitudinal stripes above the lateral line, large pharyngeal teeth in a single row and whisker-like maxillary barbels. Its numbers are threatened by large-scale agriculture and the building of dams for hydropower, and it is listed on CITES Appendix I.
