It is the only species in the genus Psettichthys, and ranges from the Bering Sea to northern California.

The Pacific sand sole, belongs to the order Pleuronectiformes, and the family Pleuronectidae.

They are considered a flatfish due to their body shape, just like Hippoglossus (halibuts), Solea (soles), and Platichthys (flounders).

[3][4] By obtaining these colors, the pacific sand sole fish can have a better advantage of camouflaging into their surroundings; making them harder to see by their prey.

[5] These fish can be found in and around the Bering Sea, all the way down to Southern California, in the northern Pacific Ocean.
