Description: Slimy Sculpin has a broad flattened head, thin body, and expansive wing-like pectoral fins. The colouration is mottled brown to gray on the back and sides, with a whitish belly. Dark cross-bands are occasionally present on its sides. Often there are two dark, oblique saddle marks, one under each of the posterior and anterior portions of the second dorsal fin. The length of this species ranges 2-3 in.

Habitat: Slimy Sculpin occupies rocky or gravely streams and lake bottoms, darting swiftly from place to place when disturbed.
