The binni (Mesopotamichthys sharpeyi) is a species of cyprinid fish endemic to the Tigris–Euphrates Basin in the Middle East.[2] This fish mostly inhabits lakes and marshes, especially in densely vegetated places where it also lays its eggs, but periodically it moves into rivers.[2][3] This barbel is the only member in its genus, but was included in the "wastebasket genus" Barbus by earlier authors. It has declined in recent times due to habitat loss and overfishing.[1]
