Sharpnose Sculpin

Sharpnose Sculpin

A tiny sculpin of Pacific coast tidepools and shallow estuaries, the Sharpnose Sculpin ranges from the Bering Sea south to central California. Rarely exceeding 2.

5 inches, it's not a sport fish — but anglers poking around intertidal zones will occasionally turn one up, its coloration shifting from bright green to mottled brown to match whatever it's sitting on.

Also known as chabot à nez pointu

Physical Characteristics:
  • A sharply pointed snout gives this species its name and sets it apart from blunter-snouted sculpin relatives at a glance.
  • Tiny cirri (hair-like filaments) sprout from the eyeballs, head, lateral line, and the tip of each dorsal spine — a distinctive feature under close inspection.
  • Color is highly variable: nearly uniform bright green in algae-rich pools, or green to light brown with dark wedge-shaped saddles and sometimes a dark stripe along the sides.
  • Maxes out around 6.4 cm (2.5 inches); most individuals run closer to 4.4 cm — smaller than many of the invertebrates sharing its tidepool.

What to know

Habitat Distribution

  • Native to the eastern Pacific from the Bering Sea coast of Alaska south to the Big Sur coast of central California.
  • A bottom-dweller of the intertidal and shallow subtidal zones, living from the surface down to about 20 meters — most commonly in tidepools and rocky nearshore habitat.
  • Moves freely between marine, brackish, and freshwater: common in the upper reaches of estuaries and capable of pushing above tidal influence into fresh water, particularly in the northern part of its range.

Specific Spots

  • Tidepools and rocky intertidal benches are the core habitat — this fish wedges into crevices and under algae mats where wave action is moderate and cover is dense.
  • Upper estuary channels where salinity drops and rockweed (Fucus) grows along the margins; spawning activity concentrates here in the high intertidal zone.
