This lifeform is found east of the Continental Divide in North America.

Channel Catfish, Ictalurus punctatus, is found in central North  America from Canada to Florida. This species can be recognized by its forked tail and long narrow appearance. It is frequently considered a good sporting fish. Lengths of twenty  to thirty inches are common and weights of twenty to thirty pounds have been reported.

North American Catfish group, Family Ictaluridae, is found in  Canada, the United States, and Mexico. This group includes the bullheads, madtoms, and channel cats. Many of the species in this family have spines on their pectoral and dorsal fins that have poison tips. One should be most careful when handling any catfish as stings from these spines can be very painful. There are over 40 species found in North America and several more from Mexico and Guatemala. The  madtoms (Genus Noturus) has approximately 25 species.

Catfish, Order Siluriformes, are found throughout the world.   Although most of them are freshwater kinds, a few are found in a marine environment. They are characterized by having whiskers and barbels around their mouths. Many search for their food by smell and make little use of their small eyes.

Bony fish, Class Teleostomi, are a class of chordates that  include the majority of fish-like animals found on earth. They  are characterized by a bony jaw and a bony skeleton. They are  found in both fresh and marine waters.

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.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
