The gunnels are a family, Pholidae, of marine fishes in the order Perciformes. They are elongated, somewhat eel-like fishes that range from the intertidal zone to depths of 200 m (660 ft), though the majority are found in shallow waters. Most are restricted to the North Pacific, ranging as far south as Baja California and East China. They typically reach a maximum length of 20–30 cm (8–12 in).
