Cypriniformes

Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches and relatives. This order contains 11-12 families, over 400 genera, and more than 4,250 species, with new species being described every few months.

Taxonomy

The Cypriniformes is the largest order of fish in the world, containing over 30% of all known fish species. The order is divided into two superorders: the Superorder:Ostariophysi and the Superorder:Otophysi. The Ostariophysi includes the families Family:Catostomidae (suckers) and Family:Cyprinidae (carps and minnows), while the Otophysi includes the families Family:Cobitidae (loaches), Family:Gyrinocheilidae (algae eaters), and Family:Balitoridae (hillstream loaches).

Characteristics

Cypriniformes are most diverse in tropical Asia and North America. They have a single dorsal fin and no adipose fin. They are distinguished by their pharyngeal teeth, which are modified gill rakers functioning as grinding surfaces, and by their lack of stomach, with the esophagus opening directly into the intestine.

Ecology

Cypriniformes are found in a wide range of habitats, from high mountain streams to lowland rivers, ponds, and lakes. They are generally freshwater fish, although some species can tolerate brackish conditions. Many species are of great economic importance as food fish, while others are popular in the aquarium trade.

Conservation

Many species of Cypriniformes are threatened by habitat loss, pollution, and overfishing. Conservation efforts are focused on habitat protection and restoration, as well as the establishment of protected areas.
