Northern pike are most often olive, shading into yellow to white along the belly. The flank is marked with short, light barlike spots and there are a few to many dark spots on the fins. The lower half of the gill cover lacks scales and they have large sensory pores on their head and on the underside of the lower jaw which are part of the lateral line system. Unlike the similar-looking and closely related muskellunge, the northern pike has light markings on a dark body background and fewer than six sensory pores on the underside of each side of the lower jaw.
