Range and Identity
Cottus gulosus is the original identity retained here. Older accounts span Pacific coastal drainages and the Sacramento-San Joaquin system while excluding some neighboring basins. Because western sculpin classifications have changed, that entire historical outline should not automatically define every modern population under this name.
Habitat and Behavior
Traditional accounts describe sand and gravel riffles in headwaters and creeks, plus runs and backwaters in larger rivers. These records provide habitat context without making the common name an exclusive rule. Backwater occurrence and riffle occurrence describe different channel settings.
Food and Life History
An upper measurement from a broad historical treatment is not assigned as a verified modern species maximum here. The same care applies to diet and reproductive timing. A record becomes more useful when its original scientific determination, collection place and later revision remain linked.
Field Note
Keep the identification source with the stream name. That allows older Riffle Sculpin records to be evaluated when a regional population receives a revised scientific treatment.
