Pholis gunnels are predominantly found in the temperate and boreal wasters of the North Pacific Ocean but
P. fasciatus and
P. gunnellus are found in the Arctic and North Atlantic Oceans, the only gunnels to occur outside the Pacific Ocean. These fishes are found in rocky areas in the intertidal zone and in the shallow waters below the low tide mark. They feed on invertebrates and fish eggs. They are
oviparous, laying eggs in a large mass which is guarded. ==References==
