The razorback sucker, also known as the "humpback sucker", is a species that can grow more than 600 mm (2 feet) in length, weigh more than 3 kg (6 pounds), and live 40+ years.
Examination of the stomach contents of adult razorback suckers from Lake Mohave indicate that the species is a benthic feeder (bottom of a sea, lake, or deep river), whose diet includes planktonic crustaceans, diatoms, filamentous algae, and detritus (fragments of decomposed plants or animals).
