Habitat

Petrale sole are native to the Pacific, ranging from the Bering Sea to Baja California. They are most abundant off the west coast of the United States and less common in the northern parts of its range. Petrale sole adults inhabit depths from 80 to 550 metres and show tolerance for a wide range of bottom temperatures across their range. They occupy the waters of the continental shelf and slope. Both adults and juveniles show an affinity for sand, sandy mud and occasionally muddy substrates. Juveniles feed primarily on mobile prey, such as cumaceans, carideans, and gammarid amphipods. Adults are piscavores. Petrale sole populations off the west coast of Canada were depleted by the 1980s but some rebuilding had occurred by the late 1990s.
