There are many distinct kinds of fish that exist in the world, each with its own anatomy. Fish come in a variety of shapes, colors, and sizes, yet they all share some characteristics.
Fish are vertebrates, which means they have a backbone like humans. Fish are aquatic animals, which means they live in water. Fish are cold-blooded animals because they cannot regulate their body temperature based on their surroundings.
Fish Body Parts
The morphology of fish is another term for fish anatomy. Studying different sections of fish will help you learn the names of different fish body parts in English. It will also boost your curiosity about aquatic bodies and aquatic delights. We will learn about the interior and external body parts of the fish in this section.
Let's start with a closer look at a fish's body!
Fish Body Parts
General Body of a Fish
Mainly there a four general body areas of a fish these are:
Dorsal refers to the back. The belly is found in the Ventral region. The fish's head is known as the anterior area, and the tail is located at the posterior end. A fish's body is divided into three main sections: the head, the trunk, and the tail. The brain, the eyes, the nostrils, and the mouth are all housed in the head. The trunk is the fish's primary body, and it contains the skeleton, spinal cord, and all of the internal organs.
Fish Parts Name
Anal Fin:- The anal fin is present on the fish's ventral (bottom) portion, towards the tail. When swimming, this fin helps to maintain the fish and provides balance.
Caudal Fin:- Fins are located in various sections of a fish and serve various functions. The caudal fin, for example, is typically used to accelerate the movement. As a result, it is known as their tail fin.
Dorsal Fins:- Dorsal fins are present on the top of the fish. These fins help to support the fish and manage its movement into the water. They prevent the fish from turning on its side by expanding the lateral surface of the body.
Scales:- Scales are thin, protective plates covering the body of the fish. They aid in the lowering of drag in water (the force that opposes movement) and the protection of the fish from predators.
Eyes:- It gives the fish sight, which is mostly used for locating food, predators, and opponents. They are positioned laterally on the upper half of the fish's side. Fishes in the deep sea have large eyes, whereas fish in a highland stream have small eyes.
Gills:- The fish's gills are positioned on either side of its head. They are used to release carbon dioxide while taking oxygen from water.
Gill Cover:- They are known as the operculum and are normally present in bony fishes. They offer facial support and cover for the gills, which allows the fish to feed and breathe.
Lateral Line:- The lateral line is a network of pores that extends the fish's body. These pores detect vibrations in the water and detect water movement.
Mouth:- This is the fish's primary feeding organ. The form of a fish's mouth is determined by its size, the food it consumes, and the depth of water in which it floats.
Nostril:- Fish nostrils are positioned on the top of the head and allow the fish to smell the water. Their nostrils are not involved in the respiratory process. Fish can tell whether another fish is hurt and if they need to escape from predators by smelling the water.
Pectoral Fin:- They are found behind the gill cover in pairs on both sides of the fish. They serve various functions in different types of fish. For example, they generate a lifting force in a shark while assisting flying fishes to fly.
Pelvic Fin:- The pelvic fins are paired and placed at the fish's ventral (bottom). They assist the fish stop moving and providing stability.
