Following the discovery that the mysterious mountain carps are a peculiar lineage of cyprinids, they are included herein, tentatively as subfamily Psilorhynchinae. The fish in this family are native to North America, Africa, and Eurasia. The largest cyprinid in this family is the Giant Barb (Catlocarpio siamensis), which may grow up to 3 m (10 ft). The largest North American species is the Colorado Pikeminnow (Ptychocheilus lucius), of which individuals up to 6 ft (1.8 m) long and weighing over 100 pounds (45 kg) have been recorded. On the other hand, many species are smaller than 5 cm (2 in). As of 2008, the smallest known freshwater fish is indeed a cypriniform, Danionella translucida, reaching 12 mm at the longest.
