The Lost River sucker (Deltistes luxatus) is a species of ray-finned fish in the family Catostomidae. It is the only living member of the genus Deltistes. It is found only in California and Oregon. Its population is much reduced from historical numbers for a number of reasons. It is a federally listed endangered species of the United States. This species is known as the C’waam by the local Native American Nation, the Klamath Tribes. This fish is one of the largest suckers, capable of reaching 86 cm (34 in) in length. It can be identified by its long snout with a small hump on top. It is dark on the back and sides and whitish or yellowish on the belly. Its lifespan can exceed 40 years. It does not reach sexual maturity until six to 14 years of age, most maturing around age 9.
