Northern Pike (Esox lucius) is one of the most popular sporting fish in the world. It is found both in North America and in Europe. These fish are great fighters and can reach very large sizes. Examples measuring thirty inches and weighing fifteen pounds are frequently caught with a hook and line. Records for this species are usually over forty inches and twenty pounds. It is found through almost all of Canada and Alaska and on into Eurasia. It is found as far south as central Missouri but is not found in the deep south of the United States. This fish is usually spotted with light colored spots. Although some anglers think this is a good eating fish, many people feel that the large number of small bones in the meat are just too much of a problem so the fish is frequently not eaten when caught.

Backboned Animals (Phylum Chordata) are the most advanced group of animals on earth. These animals are characterized by having a spinal cord or backbone. Most members have a clearly defined brain that controls the organism through a spinal cord. Fish, amphibians, reptiles, birds, and mammals are in this phylum.

Currently, some taxonomists believe that the fish should be divided into two groups (sharks and regular fishes) and that there are some other primitive groups in the phylum such as hagfish or lampreys.
