Has your teacher ever brought up legs while discussing the anatomy of fish in class? Fish that can walk, perhaps? No, I stake. This is due to the fact that fish typically lack legs. Furthermore, it would be absurd to even consider fish with legs since, given that they spend their whole lives in water, why would they have legs? We will discuss 10 different types of fish with legs.
The enigmatic planet is full of wonders, though, and some fish species have legs and can move even outside of water to contradict that occurrence. However, this form of walking is more quadrupedal than bipedal, as is obvious. Since having legs would make swimming challenging for fish, it is difficult to envisage fish having legs. There is evidence that many aquatic creatures can, though. Mudfish, handfish, and Garnai are fish that have evolved to walk on the ground and have appendages resembling legs. Here is a list of all fish with legs.
Fish With Legs
1. Red-lipped Batfish
One of the strangest sea species is the red-lipped batfish. It is an anglerfish, but unlike other species, it goes above and beyond with its peculiar characteristics. With its four thin pseudo legs, the red-lipped batfish adapts to its surroundings as a bottom-dweller. These legs enable the fish to wander and perch on sandy reefs on the ocean floor, enhancing its ability to feed. Intriguingly, the legs are better suited for walking than swimming (they have a clumsy swimming style).

2. Frogfish
The only limbless species you are likely to encounter is the frogfish. The Anglerfish family includes the Frogfish. To put it simply, these species have dorsal fins that function as limbs. The dorsal fin has grown to be larger and more adaptable than in other species, giving them the appearance of having limbs. This species is frequently encountered in tropical and continental aquatic settings. Little creatures have a lot of strength including frogfish. The small fish saunter around hunting for possible prey. Due to the peculiar limbs that surround their body, they are securely concealed.

3. Mudskippers
At least 25 species of tiny tropical fish in the Oxudercinae family go by the collective name “mudskipper.” They really enjoy exploring dirty rivers and wetlands. Although each species is distinct, fish generally have noteworthy blunt heads and distinctively large, moveable projecting eyes. Mudskippers are just as bizarre as Red-lipped batfish, if not more so. These bizarre-looking fish have a natural curiosity that drives them to seek out life on land. And what’s this? They are capable of doing it.

4. Batfish
Due to the fact that both batfish and frogfish have expanded dorsal fins that serve as limbs, they are very similar. These two species are both livings, breathing anglerfish. Due to their fins, batfish may move more freely on the ocean floor. Despite sharing many characteristics with frogfish, batfish are very different from them. About 60 different varieties of batfish exist.
They lack the physical prerequisites for swimming. However, they manoeuvre around the bottom using their fins. Researchers have noted that they are recognized to have off of the oddest appearances of any animal discovered in the ocean, with their flathead, slim physique, and walking actions.

5. Tiktaalik Roseae
Even though the Tiktaalik roseae fish is extinct, we decided to include it because, when it was alive 375 million years ago, it showed signs of walking. As shown by fossil evidence, this enormous fish, which could reach lengths of up to three meters, possessed strong fins that served in a manner similar to tetrapod limbs. It was a fully aquatic creature that could be found swimming in the water but was also not afraid to stroll on mudflats and riverbanks.

6. Handfish
Small and unusual fish known as handfish belong to the same anglerfish family as frogfish. Because they are poor swimmers, handfish, like their distant cousins, prefer to stroll rather than swim in the water. Additionally, although lacking legs, the tiny marine animals can easily travel across ocean floors because of the evolution of their pectoral fins, which have grown to resemble large hands. However, handfish lack lungs, just as mudskippers and lungfish, therefore they can only walk on water.

7. Lungfish
A group of at least six fish species from the Protopteridae family is referred to as lungfish. They are among the oldest fish you can find. The fins of lungfish are a superb illustration of how fins turned into legs, claims Science Daily. For instance, the African lungfish inhabits swamps, wetlands, and freshwater rivers. However, they also have a few peculiar, fascinating adaptations that help them feel at home on dry land.
The lungfish can live on the ground because it can breathe oxygen, as suggested by its name, and hence one of the most amazing land and water animals in the world. It cannot, however, move on the ground. Due to evolution, these extraordinary animals have special gills and lungs that enable them to breathe oxygen and live below.
They appear to be moving along sea floors thanks to the distinctive fins on their bodies. If you were wondering where these strange fish come from, they have been around for a very long time. However, the archaeological data points to a Jurassic age for them. Scientists are inspired by these species’ lungs and ability to move on the ocean’s surface.
8. Polypterus Bichir
Polypterus bichir, often known as Nile bichir, is a huge polypterid fish with a flat head and cylindrical body. The fish that resembles an eel is so mysterious that even though it lacks legs and fins that resemble hands, it walks like a tetrapod. It employs pectoral fins that are placed tactically like lizard legs. The bichir lives in shallow waters of small rivers and ponds, where it only ventures ashore to stroll. The bichir has a set of lungs that allow it to breathe in the open air when it is near the water’s surface, despite the fact that it is unable to walk on land.

9. Axolotl
Contrary to popular belief, the axolotl isn’t actually a fish. It is easy to confuse this species for one with limbs and a dorsal fin due to its incredibly prominent gills. The Mexican walking angler fish is the most common name for it. This strange little creature is actually a neotenic amphibian.
If you’re curious about what it alludes to, it’s a salamander that changes but keeps its lungs and stays in the sea. It’s a species of amphibious animal that has historically been connected to fish. Axolotls are commonly maintained as pets in aquariums despite being marine animals that can be found in a warm ocean.

10. Coelacanth
Large, enigmatic, and living in the ocean’s depths, the coelacanth has a lifespan of about 100 years. The lateral fins of the extinct species, which extend from the limbs that resemble an abdomen, serve as a distinctive feature.
The species, which is thought to move deep inside the ocean, is said to use these coelacanth pseudolegs to walk back and forth in the water like a running calf. The way that vertebrate animals walk is comparable to that of humans. Unexpectedly, until 1938, when they discovered a number of healthy Coelacanths in South Africa, scientists believed the species was endangered.
