Introduction

While most people recognize that there are different types of fish, few know that there are two main types: cartilaginous fish and bony fish. In this article, we will explore the fundamental differences between them and explain the characteristics that make each type unique.

Cartilaginous Fish

Cartilaginous fish are a class of marine animals that include sharks, rays, and chimeras. Like the other members of their class, cartilaginous fish have skeletons made of cartilage. This makes them lighter than bony fish, allowing them to swim more quickly and agilely.

• Skeleton made of cartilage
• Lighter than bony fish
• They swim quickly and agilely
• Examples: sharks, rays, chimeras

Tiburones

Sharks are the best known type of cartilaginous fish. Sharks have a thin, slender body that allows them to swim quickly and change direction easily. Additionally, their skin is covered in dermal denticles, which help them stay hydrodynamic and catch prey more effectively.

Stripes

Rays are cartilaginous fish that resemble sharks in shape but have flat, wide bodies and a long, thin tail. In addition, they have spines on their tail and on the sides of their body to protect themselves from predators.

Bony Fish

Bony fish are another type of marine animals that include most of the fish we see in aquariums and in the ocean. Unlike cartilaginous fish, bony fish have a bony skeleton, which gives them a stronger and more rigid structure.

• bone skeleton
• Greater structure and rigidity
• They swim slowly and steadily
• Examples: salmon, tuna, hake

Salmon

Salmon are a common example of bony fish. They are known to be migratory fish that swim upstream to spawn. In addition, its meat is highly valued for its flavor and texture.

Tuna

Tuna are another well-known type of bony fish. These animals are found in all the world's oceans and are valued for their meat rich in omega-3. Additionally, they are often used in commercial fishing.

Conclusion

In summary, cartilaginous fish and bony fish are two fundamental types of marine animals. Both have unique characteristics that allow them to survive in their natural habitat, such as their skeleton or their ability to swim fast or slow respectively. We hope that now you have a better knowledge of these two classes of animals and can appreciate and value the diversity of marine life.
