Greetings, Sobat Penurut!

Are you a fish enthusiast? Do you love exploring the underwater world? If yes, then you must be curious about how many fish species exist in the world. Well, in this article, we will discuss everything you need to know about the number of fish species in the world. So, let’s dive in!

The Importance of Fish

Fish are not only a source of food for humans but are also an essential component of the ecosystem. They play a crucial role in maintaining the balance of marine life. Fish help to control algae, maintain coral reefs, and provide food for larger marine animals. Thus, it is essential to have a good understanding of the number of fish species in the world.

What Are Fish?

Before we dive into the number of fish species, let’s first understand what fish are. Fish are aquatic animals with gills for breathing, fins for swimming, and scales for protection. Fish are cold-blooded vertebrates and belong to the animal kingdom’s phylum Chordata.

The Number of Fish Species in the World

According to the Food and Agriculture Organization of the United Nations, there are over 30,000 fish species in the world. However, this number is constantly changing as new species are discovered, and some become extinct. The actual number of fish species in the world can be challenging to determine due to the vastness of the ocean and the difficulty in identifying and classifying them.

Classification of Fish Species

Fish species are classified into different categories based on their characteristics. The three main categories of fish are:

  1. Bony fish: These are fish with skeletons made of bone and are the most common type of fish.
  2. Cartilaginous fish: These are fish with skeletons made of cartilage and include sharks and rays.
  3. Jawless fish: These are fish without jaws and include hagfish and lampreys.

Types of Fish Species

Fish species can be further classified into different types based on their habitat, feeding habits, and other characteristics. Here are some of the types of fish species:

1. Freshwater Fish

Freshwater fish are fish that live in freshwater bodies such as rivers, lakes, and ponds. Some of the most common freshwater fish species include trout, catfish, and bass.

2. Saltwater Fish

Saltwater fish are fish that live in the ocean or other saltwater bodies. Some of the most common saltwater fish species include tuna, salmon, and swordfish.

3. Deep-Sea Fish

Deep-sea fish are fish that live in the depths of the ocean, typically below 200 meters. These fish have adapted to living in extreme conditions such as darkness, cold temperatures, and high pressure.

4. Herbivorous Fish

Herbivorous fish are fish that feed on plants and algae. Some of the most common herbivorous fish species include carp, tilapia, and silver dollar fish.

5. Carnivorous Fish

Carnivorous fish are fish that feed on other fish or animals. Some of the most common carnivorous fish species include sharks, barracudas, and pikes.

6. Omnivorous Fish

Omnivorous fish are fish that feed on both plants and animals. Some of the most common omnivorous fish species include catfish, trout, and carp.

The Importance of Identifying Fish Species

Identifying fish species is essential for various reasons, including:

  • Conservation: Knowing the number and types of fish species helps in developing conservation strategies to protect endangered species.
  • Human Health: Identifying fish species can help in identifying edible and poisonous fish species.
  • Research: Accurate identification of fish species is crucial for scientific research and data collection.
