Humpback chub (Gila cypha)

The Humpback chub (Gila cypha) is a freshwater fish of the family Cyprinidae.

Biology

Adults inhabit swift rocky runs and flowing pools. The hump at the back of the head directs the water current down on the Humpback chub's flat head and enables the fish to maintain position in the swift Colorado River.
