What are Fish?

Fish are aquatic vertebrates that breathe through gills and have fins for swimming. They are cold-blooded, which means their body temperature changes with their environment. Fish come in a wide variety of shapes, sizes, and colors, and they can be found in almost every body of water on Earth, from the deep sea to freshwater rivers and lakes.

Bony Fish

Bony fish are the most common type of fish, and they make up the majority of fish species. They have a skeleton made of bone, and their scales are smooth and overlapping. Bony fish can be found in both saltwater and freshwater environments, and they range in size from tiny minnows to massive tuna and marlin.

Cartilaginous Fish

Cartilaginous fish, also known as elasmobranchs, have a skeleton made of cartilage rather than bone. This group includes sharks, rays, and skates, and they are found in oceans around the world. Cartilaginous fish have rough skin covered in tiny scales called dermal denticles, and they are known for their sharp teeth and predatory behavior.

Jawless Fish

Jawless fish are the most primitive type of fish, and they have been around for millions of years. They lack jaws and instead have a circular mouth with rows of teeth for sucking in food. Lampreys and hagfish are the two types of jawless fish, and they are found in both freshwater and saltwater environments.

Where Do Fish Live?

Fish can be found in almost every body of water on Earth, from saltwater oceans to freshwater lakes and rivers. Some fish are adapted to specific environments, such as deep sea fish that can survive extreme pressure and darkness, or Arctic fish that can live in icy waters. Other fish can adapt to different environments, such as salmon that are born in freshwater and migrate to the ocean to mature.

Ocean Fish

Ocean fish live in saltwater environments, and they make up a large portion of the world’s fish species. They can be found in all ocean zones, from the surface to the deep sea, and they range in size from tiny plankton to massive whales. Some common types of ocean fish include tuna, salmon, cod, haddock, and swordfish.

Freshwater Fish

Freshwater fish live in rivers, lakes, and other bodies of freshwater. They make up a smaller portion of the world’s fish species, but they are still diverse and important for their ecosystems. Freshwater fish can be found in different zones of their environment, from shallow streams to deep lakes, and they range in size from tiny minnows to large catfish and sturgeon. Some common types of freshwater fish include trout, bass, pike, and carp.
