It connects the brain with the rest of the body and transmits sensory information from the body to the brain, as well as the brain’s instructions to the rest of the body. Fish are animals that are cold-blooded and have fins and a backbone. They filter the liquid waste materials from the blood, which are then expelled from the body. The nostrils of fish do not open into the back of the mouth as do those of mammals, and are not, therefore, for breathing. The liver is also important in destroying old blood cells and maintaining adequate blood chemistry, in addition to playing a role in the excretion of nitrogen (waste). Parts of a Fish with Examples. Paired nostrils, or nares, in fish are used to detect odors in water and can be quite sensitive. This organ with projections similar to fingers is located near the junction of the stomach and intestines. The kidney is also extremely important in regulating the concentrations of water and salt in the body of the fish, which allows certain species to exist in fresh or salt water, and in some cases in both, such as snook or tarpon. The eggs, of certain fish are considered a delicacy, as in the case of sturgeon caviar.

Fishes such as catfish have anotherfleshy lobe behind the dorsal fin, called an adipose (fat) fin that is not illustrated here. The lateral line is a sensory organ consisting of fluid filled sacs with hair-like sensory apparatus that are open to the water through a series of pores, creating a line along the side of the fish.
