Fish are among the most diverse animals on Earth. They live in quiet ponds, fast-moving rivers, colourful coral reefs, deep oceans, and many other aquatic environments. Learning the different types of fish can help English learners improve their vocabulary while also understanding the natural world.
This visual vocabulary guide introduces more than 250 fish names in English. You will discover familiar aquarium fish, freshwater species, ocean fish, edible fish, powerful predators, bottom-dwelling species, and rare deep-sea animals. Each category includes short descriptions that highlight the fish’s appearance, habitat, behaviour, or most recognisable feature.
Some species appear in more than one category because a fish may be freshwater, edible, predatory, or popular in aquariums at the same time. Use the pictures to connect each name with its appearance, and return to the alphabetical list whenever you need a quick vocabulary review.
What Are Fish?
Fish are aquatic vertebrate animals, which means they live in water and have backbones. Most fish take oxygen from the water through gills and use fins to swim, balance, turn, and stop. They can live in freshwater, saltwater, or both at different stages of their lives.
Most fish are cold-blooded, so the temperature of their bodies changes with the surrounding water. However, fish are extremely diverse, and not every species has the same body shape, scales, habitat, or reproductive method.
Simple Definition of a Fish
Fish are aquatic animals with backbones that usually breathe through gills and swim using fins. They may live in freshwater, saltwater, or both during different stages of life.
Where Do Fish Live?
Fish live in almost every type of natural water environment. Their habitats include rivers, streams, lakes, ponds, wetlands, coral reefs, coastal waters, deep-sea trenches, and the open ocean.
Some fish remain in one habitat throughout their lives. Others, such as many salmon, travel between freshwater and saltwater.
Are All Aquatic Animals Fish?
Not every animal living in water is a fish. Whales, dolphins, and seals are mammals. Octopuses and shellfish are invertebrates, while jellyfish and starfish are not true fish despite their names.
Features of Fish
Fish species differ greatly, but many share several important physical and biological features. These characteristics help them breathe, move, find food, avoid predators, and survive in aquatic environments.
Gills
Most fish use gills to remove dissolved oxygen from water. Water passes across the gills, where oxygen enters the bloodstream and carbon dioxide leaves the body.
Fins
Fins help fish swim, turn, stop, balance, and maintain direction. Different fins perform different jobs, and their shape varies according to the fish’s habitat and swimming style.
Scales and Skin
Many fish have scales that protect their bodies. Others have smooth skin, bony plates, tiny scales, or scales that are deeply embedded and difficult to see.
Streamlined Body
Many active swimmers have streamlined bodies that reduce resistance in the water. This shape helps species such as tuna, mackerel, and sharks move efficiently.
Cold-Blooded Body
Most fish depend on the surrounding water to regulate their body temperature. Their activity and metabolism may change when the water becomes warmer or colder.
Backbone
True fish are vertebrates, meaning they have a spinal column or backbone. Sharks and rays also have backbones, although their skeletons consist mainly of cartilage rather than bone.
Different Reproduction Methods
Many fish reproduce by laying eggs. Others give birth to live young, while a few species protect eggs or developing babies inside specialised body structures.
List of Fish Names in English
The following fish names are arranged in practical groups based on habitat, appearance, behaviour, human use, and popularity. These categories make the vocabulary easier to learn, although some species logically belong to more than one group.
Common and Domestic Types of Fish
Common fish are species that many people easily recognise. The term “domestic fish” generally refers to fish kept in homes, ponds, farms, or aquariums. Unlike dogs or cattle, most pet fish are better described as captive or selectively bred rather than fully domesticated.

Alligator Pipefish | This long, narrow fish has a tube-shaped snout and a rigid body. Like seahorses, male pipefish carry the developing eggs. |
Anglerfish | Many anglerfish have a modified fin spine that acts like a fishing lure. Deep-sea species may use natural light to attract prey in darkness. |
Bichir | Bichirs are ancient-looking African freshwater fish with armoured scales and separate dorsal finlets. They can also breathe atmospheric air. |
Black Dragonfish | Black dragonfish live in deep ocean water and have dark, narrow bodies. Their large teeth and light-producing organs help them hunt in darkness. |
Blind Cavefish | Blind cavefish live in underground rivers and caves where sunlight does not reach. Some populations have reduced eyesight and little body colouring. |
Bluefin Notho | This small African killifish is known for its bright blue, red, and yellow markings. It completes its life cycle quickly in temporary pools. |
Bowmouth Guitarfish | The bowmouth guitarfish has a ray-like head and a shark-like body. It feeds on shellfish, crustaceans, and other animals near the seafloor. |
Candiru | Candiru is a name used for several small Amazonian catfish. Some species feed on the blood of larger fish by entering their gill areas. |
Cookiecutter Shark | This small shark attaches to larger marine animals and removes round pieces of flesh. Its bite leaves a distinctive circular mark. |

Tripod Fish | Tripod fish have extremely long fin rays that support them above the seabed. They face the current and wait for small drifting animals. |
Types of Flat and Bottom Fish
Flatfish usually have flattened bodies and spend most of their time close to the seabed. Other bottom-dwelling fish may not be flat, but they commonly rest, hide, hunt, or feed near sand, mud, rocks, and coral.
Fish name | Description |
|---|---|
Flounder | Adult flounders have flat bodies with both eyes positioned on one side. Their mottled colouring helps them disappear against sand or mud. |
Halibut | Halibut are large flatfish found mainly in cold northern waters. Their dark upper surfaces help them blend into the seabed. |
Sole | Sole have thin, oval bodies and small mouths. They usually remain close to sandy or muddy ocean bottoms. |
Plaice | Plaice are flatfish recognised by orange or reddish spots on their upper surfaces. They commonly live on soft seabeds in northern waters. |
Turbot | Turbot have broad, nearly circular bodies and rough upper skin. They often partly bury themselves while waiting for prey. |
Skate | Skates are cartilaginous fish related to sharks and rays. Their broad pectoral fins create a flattened, diamond-like body. |
Stingray | Stingrays have wide, flat bodies and wing-like fins. Many species possess a defensive spine on the tail. |
Monkfish | Monkfish have broad heads, huge mouths, and narrow bodies. They remain near the bottom and ambush animals that swim close enough. |
Stonefish | Stonefish rest almost motionless on rocky or sandy bottoms. Their natural camouflage makes them difficult for predators and prey to notice. |
Stargazer | Stargazers often bury themselves in sand with only their eyes and mouths visible. They attack fish and other animals passing overhead. |
Dab | Dabs are small flatfish with rough upper surfaces. They are commonly found on sandy seabeds in coastal waters. |
Guitarfish | Guitarfish combine a ray-like flattened head with a shark-like tail. They search along the bottom for shellfish, fish, and crustaceans. |
Lizardfish | Lizardfish rest on sand or coral with their heads raised. Their sharp teeth allow them to grab smaller fish quickly. |
Mudskipper | Mudskippers live around tidal mudflats and mangrove areas. They use their strong fins to move, feed, and defend territories on wet mud. |
Sanddab | Sanddabs are small flatfish that live on sandy ocean bottoms. Their mottled colouring provides effective camouflage. |
Sculpin | Sculpins have broad heads and large pectoral fins. Many species blend naturally with stones, gravel, or underwater plants. |
Sea Robin | Sea robins have large, wing-like fins and separate finger-shaped rays. They use these sensitive rays to search the bottom for food. |
Shovelnose Ray | Shovelnose rays have pointed snouts and elongated bodies. They feed on small fish, crustaceans, and buried animals. |
Torpedo Ray | Torpedo rays can produce electrical shocks for hunting and defence. Their rounded, flattened bodies are suited to bottom habitats. |
Wobbegong | Wobbegongs are carpet sharks with flat, patterned bodies. They rest on reefs and ambush fish that swim within reach. |
Types of Other Famous Fish
Some fish are widely recognised because of their unusual appearance, behaviour, biology, or cultural popularity. Several may also fit into earlier categories, but their distinctive qualities make them worth learning separately.
Fish name | Description |
|---|---|
Seahorse | Seahorses are true fish with upright bodies, curled tails, and tube-shaped mouths. Male seahorses carry developing young inside a brood pouch. |
Pufferfish | Pufferfish can swallow water or air and inflate their bodies when threatened. This makes them harder for predators to bite or swallow. |
Electric Eel | The electric eel is actually a type of knifefish. It produces electrical signals for navigation, communication, defence, and hunting. |
Ocean Sunfish | Ocean sunfish have enormous compressed bodies and unusually shortened tail areas. They often swim near the surface of the ocean. |
Mudskipper | Mudskippers can move across wet land using their fins. Their raised eyes allow them to see clearly above the mud. |
Remora | Remoras have suction discs on their heads. They use them to attach temporarily to sharks, turtles, rays, and other large animals. |
Archerfish | Archerfish shoot streams of water at insects sitting above the surface. When the insect falls, the fish quickly catches it. |
Climbing Perch | Climbing perch can breathe atmospheric air with a specialised organ. They may survive outside water temporarily in damp conditions. |
Four-Eyed Fish | Four-eyed fish swim close to the surface. Each eye is divided so the fish can see above and below the water at the same time. |
Lanternfish | Lanternfish have rows of light-producing organs on their bodies. They are extremely important food for larger animals in deep-ocean ecosystems. |
Anemonefish | Anemonefish is another name for clownfish. A protective mucus coating allows them to live safely among sea anemone tentacles. |
Boxfish | Boxfish have rigid, box-shaped bodies protected by hard armour. They swim mainly by moving their small fins. |
Butterflyfish | Butterflyfish have thin bodies, bright patterns, and small mouths. They are commonly seen around tropical coral reefs. |
Cleaner Wrasse | Cleaner wrasses remove parasites and dead skin from larger fish. Other reef animals regularly visit their cleaning areas. |
Cowfish | Cowfish are boxfish with horn-like projections above their eyes. Their hard, angular bodies give them a distinctive appearance. |
Garfish | Garfish are narrow surface-swimming fish with long, beak-like jaws. They are sometimes called needlefish in certain regions. |
Hatchetfish | Hatchetfish have deep, blade-shaped bodies. Deep-sea species use light-producing organs to hide their silhouettes from predators. |
Knifefish | Knifefish have elongated bodies and long, waving fins. Several species use weak electrical fields to navigate dark or muddy water. |
Lionfish | Lionfish are known for striped bodies and broad decorative fins. Their dorsal spines contain venom used for defence. |
Pipefish | Pipefish are close relatives of seahorses with narrow bodies and tube-shaped mouths. In many species, males carry the eggs. |
Porcupinefish | Porcupinefish inflate their bodies when threatened, causing their long spines to stand outward. This creates an effective defence against predators. |
Sand Eel | Sand eels are slender schooling fish that often bury themselves in sand. They are an important food source for seabirds and larger fish. |
Scorpionfish | Scorpionfish have excellent camouflage and often remain still on reefs or rocky bottoms. Many species possess venomous defensive spines. |
Stickleback | Sticklebacks are small fish with separate dorsal spines. Male sticklebacks often build nests and protect the eggs. |
Trumpetfish | Trumpetfish have long bodies and narrow, tube-shaped mouths. They sometimes hide beside larger fish while approaching prey. |

How to Learn Fish Names in English
Learning hundreds of fish names may seem difficult, but the process becomes easier when the vocabulary is divided into practical groups. Study a small number of words at a time and connect each name with a picture, habitat, or physical feature.
Learn Fish by Category
Begin with simple groups such as freshwater fish, ocean fish, aquarium fish, edible fish, and predatory fish.
For example, learn trout, pike, perch, and catfish together as freshwater vocabulary. Study tuna, marlin, sardine, and mackerel as ocean fish.
Grouping related words helps you understand their meanings and remember them for longer.
Use Fish Pictures
A clear picture makes an unfamiliar fish name easier to remember. Focus on one noticeable feature for each animal.
You might remember a swordfish by its long bill, a flounder by its flat body, a seahorse by its curled tail, or a pufferfish by its ability to inflate.
Picture cards, visual charts, and labelled posters are particularly useful for beginners and young learners.
Practise Singular and Plural Forms
The usual plural of fish is also fish.
- I saw one fish in the pond.
- I saw six fish in the pond.
The word fishes may be used when referring to several different species or groups.
- The reef contains many tropical fishes.
Use Fish Names in Sentences
Practise each new word in a short sentence:
- A trout lives in freshwater.
- Tuna are fast ocean fish.
- The aquarium contains several colourful fish.
- A flounder has a flat body.
- Guppies are popular aquarium fish.
- The shark moved through the open ocean.
- A seahorse has a curled tail.
- Sardines swim in large schools.
Creating your own sentences helps you remember both the meaning and correct use of each word.
Review Names Alphabetically
Use the A–Z fish list as a revision checklist. Mark the names you already recognise and choose five to ten unfamiliar words for each study session.
Review the words after one day, one week, and one month. Regular recall is more effective than reading the entire list repeatedly.

Frequently Asked Questions About Fish
How Many Types of Fish Are There?
Scientists recognise tens of thousands of fish species worldwide. The exact number changes as researchers discover new species and update the classification of known ones.
What Are the Main Types of Fish?
Scientifically, fish are commonly grouped as jawless, cartilaginous, and bony fish. In everyday language, they may also be grouped by habitat, size, appearance, behaviour, or human use.
Are Sharks Fish?
Yes. Sharks are cartilaginous fish, meaning their skeletons are made mainly of cartilage rather than bone. They breathe through gills and move using fins.
What Are Some Common Fish Names?
Common fish names include goldfish, salmon, tuna, cod, trout, carp, catfish, sardine, mackerel, tilapia, guppy, clownfish, perch, and angelfish.
What Is the Most Popular Aquarium Fish?
Goldfish, betta fish, guppies, tetras, mollies, platies, and angelfish are all widely kept. Popularity depends on location, aquarium size, experience, and availability.
Are Whales and Dolphins Fish?
No. Whales and dolphins are mammals. They breathe air through lungs, give birth to live young, and feed their babies with milk.
Is a Starfish Really a Fish?
No. A starfish is a marine invertebrate more accurately called a sea star. It does not have a backbone, fins, scales, or gills like a true fish.
Which Fish Can Live Outside Water?
Mudskippers, lungfish, climbing perch, walking catfish, and some eels can survive outside water temporarily. They still require suitable moisture, temperature, and environmental conditions.
What Is the Largest Fish in the World?
The whale shark is the largest living fish. It is a filter-feeding shark that eats plankton, small fish, and other tiny marine organisms.
Summary of Fish Names
- Fish are aquatic vertebrate animals.
- Most fish breathe through gills and move using fins.
- Fish can live in freshwater, saltwater, or both.
- They may be grouped by habitat, appearance, size, behaviour, and use.
- Aquarium fish include guppies, bettas, goldfish, mollies, and tetras.
- Common edible fish include salmon, tuna, cod, sardines, and tilapia.
- Predatory fish include sharks, pike, barracudas, marlin, and snakeheads.
- Flatfish include flounder, sole, halibut, plaice, and turbot.
- Unusual fish include oarfish, coelacanths, mudskippers, and barreleye fish.
- This guide contains more than 250 fish names in English.
Final Thoughts
Learning fish names is an enjoyable way to expand your English vocabulary while discovering the diversity of aquatic life. Instead of memorising every word at once, begin with one category, such as freshwater, aquarium, edible, or ocean fish.
Connect each name with a picture and one clear identifying feature. Use the alphabetical list for revision, practise the words in simple sentences, and review them regularly. Studying the different types of fish in organised groups will help you remember more vocabulary and use the names confidently in conversation, writing, and classroom activities.
