Myxocyprinus

Myxocyprinus is a monotypic genus of freshwater fish in the monotypic subfamily Myxocyprininae within the family Catostomidae. The only species is Myxocyprinus asiaticus, also known as the Chinese sucker.

It is a popular freshwater aquarium fish known under various common names, including Chinese high-fin banded shark, Chinese banded shark, Chinese sailfin sucker, high-fin (also spelled hi-fin) banded loach, high-fin loach, Chinese high-fin sucker, sailfin sucker, topsail sucker, Asian sucker, wimple carp, wimple, freshwater batfish, Chinese or Asian zebra high-fin shark, Chinese or Asian zebra high-fin sucker, Chinese emperor, Siamese sucker, and entsuyui in Japanese. Despite its common names, it bears no relation to real sharks. It grows to about 1.35 m (4 ft 5 in) long and is unsuitable for most home aquariums.

It has declined drastically due to pollution, dams (preventing its natural breeding migration), overfishing, introduced species and collection for the aquarium trade. As a consequence it has been placed on the Chinese list of endangered species and is a state protected species.
