Sobat Penurut, welcome to this informative article about the three types of fish. Fish are one of the most diverse and fascinating creatures on our planet, and they play an important role in our ecosystem. Whether you are a fisherman, a seafood lover, or simply curious about the different types of fish that exist, this article is for you. In this article, we will explore the three main types of fish and provide you with all the information you need to know about them.
What Are Fish?
Fish are aquatic vertebrates that breathe through gills and use fins to swim. They are cold-blooded and come in a vast array of shapes, sizes, and colors. There are over 34,000 known species of fish, making them the most diverse group of vertebrates on Earth.
The Three Types Of Fish
The three main types of fish are bony fish, cartilaginous fish, and jawless fish. Each of these types of fish has unique characteristics that set them apart from one another.
Bony fish, also known as teleosts, are the most common type of fish. They have skeletons made of bone, and their scales are made of a hard, mineralized substance called ganoin. Bony fish have a swim bladder, which helps them control their buoyancy in the water. They also have a lateral line system, which allows them to detect vibrations and changes in pressure in the water.
Types Of Bony Fish
Bony fish can be further divided into two types: ray-finned fish and lobe-finned fish. Ray-finned fish, also known as actinopterygians, have fins that are supported by bony spines. Lobe-finned fish, also known as sarcopterygians, have fins that are supported by fleshy, muscular lobes.
Examples Of Bony Fish
|Tuna, salmon, trout, carp, bass
Cartilaginous fish, also known as chondrichthyes, have skeletons made of cartilage instead of bone. They also have tough, skin-like scales called dermal denticles. Cartilaginous fish have a more primitive immune system than bony fish and rely on their tough skin and unique immune cells to ward off infections.
Types Of Cartilaginous Fish
Cartilaginous fish can be further divided into two types: sharks and rays. Sharks have a streamlined body and sharp teeth, while rays have a flattened body and a venomous barb on their tail.
Examples Of Cartilaginous Fish
|Great white shark, hammerhead shark, tiger shark
|Manta ray, stingray, electric ray
Jawless fish, also known as agnatha, are the most primitive type of fish. They have a streamlined body and no jaws or paired fins. Jawless fish have a unique feeding mechanism that involves attaching themselves to other fish and using their rasping tongue to suck out their blood and bodily fluids.
Types Of Jawless Fish
Jawless fish can be further divided into two types: lampreys and hagfish. Lampreys have a long, cylindrical body and a circular mouth lined with teeth. Hagfish have a slimy, eel-like body and produce large amounts of mucus to protect themselves from predators.
Examples Of Jawless Fish
|Sea lamprey, river lamprey
|Pacific hagfish, Atlantic hagfish

No, cartilaginous fish do not have a swim bladder.
Nah, that’s all you need to know about the three types of fish. Each type of fish has its unique characteristics and plays a vital role in our ecosystem. Whether you are a fisherman or a seafood lover, understanding the different types of fish can help you appreciate and respect these fascinating creatures even more.
If you want to learn more about fish, feel free to do your research or consult with a marine biologist or fish expert. Remember to take care of our oceans and the creatures that live in them, so they can continue to thrive for generations to come.
