Open encyclopedia reference
The Klamath smallscale sucker (Catostomus rimiculus), also known as the Jenny Creek sucker, is a species of ray-finned fish in the family Catostomidae. It is a freshwater fish that primarily inhabits the Trinity and Klamath River watersheds, as well as the overall region of the Klamath Basin in general. Within the Klamath Basin, they inhabit the area along with three other sucker fish: the Lost River sucker, shortnose sucker, and the Klamath largescale sucker. These fish can vary in length from 35 cm to 50 cm, and usually have a lifespan of around 9-15 years. They often form mixed schools with speckled dace, sculpins, and juvenile steelhead.
A population of the species separated from the Klamath River by a waterfall are called Jenny Creek suckers.
