What Are The Four Types Of Fish?

There are four main types of fish: bony fish, cartilaginous fish, jawless fish, and shellfish. Each type has unique characteristics that set them apart from one another.

Bony Fish

Bony fish, also known as Osteichthyes, are the most common type of fish. They have a bony skeleton and swim bladder that allows them to control their buoyancy in the water. Bony fish can be found in both freshwater and saltwater and come in a variety of shapes and sizes.

Some examples of bony fish include:

  • Trout
  • Bass
  • Salmon
  • Tuna

Cartilaginous Fish

Cartilaginous fish, also known as Chondrichthyes, have a cartilaginous skeleton instead of a bony one. They also have multiple rows of teeth that are constantly being replaced throughout their lifetime. Cartilaginous fish can only be found in saltwater.

Some examples of cartilaginous fish include:

  • Sharks
  • Rays

Jawless Fish

Jawless fish, also known as Agnatha, are primitive fish that do not have a jaw or a bony skeleton. Instead, they have a cartilaginous structure that supports their body. They can be found in both freshwater and saltwater.

Some examples of jawless fish include:

  • Lampreys
  • Hagfish

Shellfish

Shellfish, also known as Mollusca, are aquatic animals that have a soft body and a hard shell. They can be found in both freshwater and saltwater. Shellfish are an important source of food for both humans and other animals.

Some examples of shellfish include:

  • Clams
  • Oysters
  • Mussels
  • Snails

Characteristics Of Fish

Body Shape

The body shape of fish varies depending on the type of fish. Bony fish have a streamlined body shape that allows them to move quickly through the water. Cartilaginous fish have a flattened body shape that allows them to glide through the water. Jawless fish have a long, cylindrical body shape. Shellfish have a soft body and a hard shell that protects them from predators.

Scales

Most fish have scales that cover their body. Scales provide protection from predators and help to regulate the fish’s body temperature. The size and shape of scales vary depending on the type of fish.

Fins

Fish have fins that help them to swim and maneuver through the water. The number and placement of fins vary depending on the type of fish.

Reproduction

Fish reproduce in a variety of ways. Some fish lay eggs, while others give birth to live young. Some fish mate for life, while others mate with multiple partners.
