So, let’s dive in and explore the fascinating world of fish!

The Different Types of Fish

There are many different ways to categorize fish, but one common method is based on their physical characteristics. Fish can be divided into two main groups: bony fish and cartilaginous fish.

Bony Fish

Bony fish, also known as teleosts, are the most common type of fish. They have a skeleton made of bone, and their bodies are covered in scales. Bony fish can be further divided into two subgroups: ray-finned fish and lobe-finned fish.

Ray-finned Fish

Ray-finned fish are the most diverse group of bony fish, with over 30,000 different species. They have fins that are supported by bony spines, and their scales are usually smooth and overlapping.

Examples of Ray-finned Fish
Name Characteristics Habitat
Tuna Large, muscular fish with a streamlined body and powerful tail Ocean
Salmon Slender fish with silvery scales and a distinctive pink flesh Rivers and oceans
Trout Olive-green or brown fish with black spots and a red underbelly Rivers and lakes
Cod Large fish with a distinctive chin barbel and a flaky white flesh Ocean

Lobe-finned Fish

Lobe-finned fish are a smaller group of bony fish that have fleshy, lobed fins. They are thought to be the ancestors of land vertebrates, including humans.

Examples of Lobe-finned Fish
Name Characteristics Habitat
Coelacanth Large, prehistoric-looking fish with fleshy fins and a blue-grey color Deep sea
Lungfish Primitive fish with a lung-like organ that allows them to breathe air Rivers and lakes

Cartilaginous Fish

Cartilaginous fish, also known as chondrichthyans, have a skeleton made of cartilage instead of bone. They also have rough, sandpaper-like skin instead of scales. Cartilaginous fish can be divided into two subgroups: sharks and rays.


Sharks are some of the most feared and misunderstood creatures in the ocean. They have a streamlined body and powerful jaws filled with sharp teeth. Sharks are found in every ocean of the world, from the tropics to the polar regions.

Examples of Sharks
Name Characteristics Habitat
Great white shark Large, powerful shark with a distinctive white belly and a pointed snout Ocean
Tiger shark Aggressive shark with dark stripes on its back and sides Ocean
Hammerhead shark Unusual-looking shark with a head that resembles a hammer Ocean


Rays are flattened, disc-shaped fish that are closely related to sharks. They have a broad, flat body and a long, whip-like tail. Rays are found in both freshwater and saltwater habitats.

Examples of Rays
Name Characteristics Habitat
Manta ray Giant ray with a distinctive diamond-shaped body and two large fins that resemble wings Ocean
Stingray Flat-bodied fish with a long, barbed tail that can inflict painful stings Ocean and freshwater
