Catfish also have a maxilla reduced to a support for barbels; this means that they are unable to protrude their mouths as other fish such as carp. The functions of parts of a tilapia fish are mouth (to eat), eyes (to see), nares (nostrils to detect odors), gills (for breathing) and fins (to move, steer and stop). The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Swim (or Air) Bladder: A hollow, gas-filled balance organ that allows a fish to conserve energy by maintaining neutral buoyancy (suspending) in water. What body parts do fish have? used to propel the fish forward and to help it with steering. Terms in this set (17) anterior dorsal fin. types of fishes, and complete a live or a virtual dissection of a fish. For many species of fish the nares function as a chemical alarm system as opposed to a vocal alarm system used by birds and mammals (1). keeps the fish sitting upright. Their main function is to control the stability and direction of the fish. The median fins , that is, the dorsal, anal and ventral fins, control the rolling and yawing movements of the fish by increasing the vertical surface area presented to the water. Start studying Fins & their functions. The main parts on the outside of a fish are the gills (for breathing), the fins (for swimming and steering), and the lateral line (for detecting movement nearby). Tilapia is rich in niacin, vitamin B12, phosphorus, selenium and potassium. posterior dorsal fin. Morphology is a branch of science which deals with study of the form and features of any living organism. A fish is identified by its External Morphology. Even more impressive is the amount of vitamins and minerals in this fish. One of the fish's primary sense organs; detects underwater vibrations and is capable of determining the direction of their source. 4.39). I have taken most of the content from vtaide.com and learning parade and made into an easy PowerPoint introduction. Water is “inhaled” through the mouth, passes over the gills and is “exhaled” from beneath the operculum. Being able to name the parts of a fish will not only improve your English and bring you well on your way to sounding like a native speaker but it will also prove useful in a variety of conversations. This lesson will be one for inquisitive exploration, and hands-on learning. Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. How do these unique body parts help them survive in their watery habitats? The body of fish can be divided into two main parts Head; Body. Fish Anatomy Lesson for Kids. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The second article How a Fish is described describes the process by which these body parts are used to describe the fish. An operculum (gill cover) is a flexible bony plate that protects the sensitive gills. Children then will label a picture of the Rainbow fish, either laminated as a matching game, or individually as a writing exercise.
