Fish Anatomy
The structure of the fish is very important, as it helps the fish to swim in the water. Almost all the fish have torpedo shape and streamlined body with round nose, thicker middle part and a pointed tail. Fishes with elongated slim body are good swimmers whereas fishes with short bodies can control their turns more quickly. The shape of the fish has a lot to help them in hunting their prey. Most of the fish uses sit and wait method for hunting its prey.
The head part consists of the mouth, nostrils, and gill cover. Fishes breathe with the help of the gills present under the gill cover. Oxygen is observed by the gills as water move over the surface of the gills.
The body of the fish is protected by scales like skin or hair in other animals. The scales start to produce rings as they age with help the scientist to find out the age of the fish. Extra protection is offered to the fish by the layer of slime that covers the scales. This slime helps the fish to move faster and keep the germs off from attacking the fish skin.
The lateral line helps the fish to know what is around them in the water body. These lines are sensitive to pressure, vibration, movement and sound. Fishes swim with the help of fins. The large muscle body of the fish does most of the work but the fins help in balancing and in turning. Some fishes have large and spiny fins that help them to protect against their predators.
