About Pacific Flatnose

The Pacific flatnose is a deep-water North Pacific fish recorded from Japan through the Bering Sea and south to the Gulf of California, with records at Johnston Island.

Range and natural history

It is especially associated with the lower continental slope, often around 800–1,800 meters. A short chin barbel, pointed snout and long soft-rayed fins help characterize the body. Color varies from blue-gray or olive to very dark violet or blue-black, with darker fin margins.

The fish feeds on bottom-dwelling invertebrates and is encountered in deep trawl fisheries. The FishBase account notes differences in where the sexes occur but leaves large-scale movement unresolved. A catch from a feeding area therefore should not automatically be interpreted as evidence for a known migration route.
