DUNGUN (Dec 6, 2011): The world’s smallest species of fish, ‘Cyprinidae’ measuring 7.8mm, and found in the Bukit Bauk swamp here, has been carefully preserved to prevent the endangered species from the brink of extinction.
The family Cyprinidae, from the Ancient Greek kyprînos (κυπρῖνος, “carp”), consists of the carps, the true minnows, and their relatives (for example, the barbs and barbels). Commonly called the carp family or the minnow family, its members are also known as cyprinids. It is the largest family of fresh-water fish, with over 2,400 species in about 220 genera. The family belongs to the order Cypriniformes, of whose genera and species the cyprinids make up two-thirds.
Many species are smaller than 5 centimetres (2.0 in). As of 2008, the smallest known freshwater fish is a cypriniform, Danionella translucida, reaching 12 millimetres (0.47 in) at the longest.
The largest cyprinid in this family is the Giant Barb (Catlocarpio siamensis), which may grow up to 3 metres (9.8 ft). The largest North American species is the Colorado Pikeminnow (Ptychocheilus lucius), of which individuals up to 6 feet (1.8 m) long and weighing over 100 pounds (45 kg) have been recorded.
