Range and Identity
Cottus perplexus is recorded from the Snohomish and Puget Sound region south toward the Rogue system. A drainage name and complete identification are useful because several western sculpins can share nearby waters. Geographic proximity alone cannot determine which species an observation represents.
Habitat and Behavior
Adults commonly occupy gravel or rubble pools and riffles. Studies report more riffle use where certain other sculpins are absent and more pool use where they coexist. This is a documented habitat association, rather than proof that one current condition is obligatory everywhere.
Food and Life History
The maximum reference is ten centimeters total length, with eight centimeters given as a common size. Reports from still muddy waters have identification uncertainty and are not used as firm evidence. No independent maximum mass or detailed diet is inferred from those tentative records.
Field Note
Note other sculpins present when that information is known. Fish-community context can help explain why the same species appears in different parts of separate streams.
