Freshwater sculpins, with their characteristic large heads and fins, are bottom dwellers that can be found in cold, fast-moving streams throughout North America. Biologists have long suspected that there were undescribed species of sculpins in the Upper Columbia River Basin, but lacked the tools to recognize them. Cedar sculpin populations were previously thought to be shorthead sculpin (Cottus confusus), an understandable misidentification given that sculpins are notoriously difficult to identify based on their physical features.
