Ratfish are deep water fish which take their name from their long slender tails.
The flesh is edible, and ratfish liver oil is used for gun oil and fine instruments.
English Sole and Spotted Ratfish were by far the most common species, collectively, contributing more than 40% of all individuals sampled.
Spotted Ratfish was the only species for which no trend or apparent change in abundance over the sampling period was observed (Table 2; Fig.

Overall, spotted ratfish (Hydrolagus colliei), spiny dogfish, and flatfish were the dominant taxonomic groups in the survey.
Partial CCA results for the October+July and all-months samples confirmed that 160 m was dominated by spotted ratfish and small spiny dogfish, but that Pacific hake (Merluccius productus), rex sole (Glyptocephalus zachirus), and dover sole (Microstomus pacificus) also typified that depth (Fig.

Species in this analysis were limited to oviparous elasmobranchs, which encompassed a diverse group of 13 chondrichthyan fishes: a chimera, the spotted ratfish
(Hydrolagus colliei), two catshark species (Scyliorhinus spp.
Some fishes were readily identifiable to species; for example, lingcod, ratfish
(Hydrolagus colliei), canary rockfish (Sebastes pinniger), and wolf-eel (Anarrhichthys ocellatus) were very distinctive.
