The World’s Ten Largest Eels, According To Their Length And Sizes.


Eels initially appeared on the planet more than 65 million years ago, and they are still alive and well now. There are approximately 800 different species of eel found worldwide, and the majority of them are in good condition.

Regardless of whether they reside in fresh or saltwater, these ray-finned fish find a method to assert their dominance over their environment.

It’s not difficult to envisage these mysterious creatures as strong sea monsters, given that they’re part fish, part snake, and have jaws full of razor-sharp teeth to match.

Despite their intimidating look, eels serve an important part in the health of marine ecosystems. This kind of nocturnal predator preys on everything from fish to crabs to other eels because it has almost no natural predators.

Some species could live for up to 20 years and grow to huge proportions. Even though they occur in various sizes and shapes, ranging from tiny dwarf eels to the massive moray, the largest species captures our attention.

These specimens have earned the eel the moniker “The Devil of the Sea” because of their enormous size and dimensions.

In order to decide which eel species is the largest, you must compare both their length and weight, with weight being the most important factor to consider.

Meanwhile, some species, such as electric eels and wolf eels, are called eels; they are members of separate animal groups and are not true eels in the literal sense of the word.

As a result, despite their enormous size, they do not rank among the world’s greatest eels. After considering all of this, here is a list of the top 10 largest eels on the planet.


10). Southern Conger Eel

southern conger eel

The southern conger (Conger verreauxi) is a family or member of the Congridae family and is found in the southern United States. The largest of them can grow to be 6.5 feet long and weigh up to 11 pounds at their full size.

Their elongated, brown-grey bodies have a similar appearance to the most common species of conger eel, but they are smaller. In the waters off the southern shores of Australia and New Zealand, they can be found regularly.

Typically, southern congers can be found in stony reef environments at depths of up to 330 feet. As opportunistic, nocturnal hunters, they will consume anything from fish to crustaceans and even other eels if the opportunity presents itself, even other eels.

Currently, they are classified as a species of Least Concern by the International Union for Conservation of Nature.


9). California Moray Eel

It was named because it is the only species of moray that can be found off the coast of California, hence earning it the name California moray.

They could grow to be up to 5 feet long and weigh nearly 15 pounds at their heaviest when they are fully grown. They have a variety or lots of appearances, ranging from a mottled brown tint to almost green.

While the vast majority of morays are found in temperate waters, the California moray is one of the rare species that can be found in subtropical seas.

If you want to see one in the wild, look for bouldered areas around 120 feet below sea level, which is where they usually live. Their primary diet consists of fish, but they will also consume lobsters, shrimp, and octopuses if available.

Because they are not commercially fished and do not have any predators, the International Union for Conservation of Nature (IUCN) classifies them as a species of Least Concern.


8). American Eel

Anglerfish (Anguilla rostrata) are migratory fish that can be found off the shore of North America’s eastern seaboard. The largest specimens can grow to be around 4 feet long and weigh up to 17 pounds at their mature size.

They range from dark green with brown shading to light grey with white bellies, with darker green being the most common. Their bodies are covered in a thin layer of mucus, giving them a bare and slimy appearance.

American eels could spend most of their life in freshwater, only venturing into the ocean to reproduce once every few years.

Females could lay up to 4 million eggs in a single cycle. Creatures like crustaceans, insects, and whatever else they can locate to eat make up their diet.

Their populations have decreased drastically in recent years due to habitat loss caused by the construction of dams along migration routes. As a result, they are listed as an Endangered species by the International Union for Conservation of Nature.


7). Moray Eel With Fangtooth

The fangtooth moray (Enchelycore anatina), sometimes known as the tiger moray or the bird-eye conger, is perhaps one of the most fearsome members of the moray family.

It is also one of the most venomous. Their mouth is lined with huge, glass-like teeth, which gives them their name. A single individual can grow to be up to 4 feet in length and weigh up to 30 pounds.

Their look is highly noticeable because of the brilliant yellow-orange and brown colour on their bodies. Their warm-weather habitats are located in the Atlantic Ocean’s warm-water zones, such as the Mediterranean Sea, the Canary Islands, and Madeira.

Fangtooths are nocturnal hunters who live and hunt in the rocky crevices of the seafloor. Crustaceans, cephalopods, and bottom-feeding fish are the primary prey for these predators.

The fangtooth moray is listed as a species of Least Concern by the International Union for Conservation of Nature.


6). Moray The Slender

The slender giant moray (Strphidon sathete) is the world’s longest eel and is the longest eel on the planet. The slim gigantic moray puts the rest of the group to shame when it comes to eels, renowned for their elongated bodies.

moray the slender

The world’s largest specimen was discovered, which measured an astonishing 13 feet in length. Even though the specifics of their weight vary depending on their size, they could weigh up to approximately 40 pounds at their heaviest.

They are normally brownish-grey in hue, yet their colour becomes paler on their bellies as they get older. They could be found in all parts of the Indian and Pacific oceans, from the Red Sea to the western Pacific, and they are very slender.

Their favourite settings are typically muddy, allowing them to blend in with their surroundings. Their main hunting habitats include river estuaries and bays, among other places. Fish, crabs, and molluscs are among the foods they eat.

The reports of The International Union for Conservation of Nature (IUCN) classified enormous morays as a species of Least Concern. Nevertheless, no research has been conducted to determine the current state of slender gigantic morays.


5). Grey Conger

The grey conger (Conger esculentus), sometimes known as the Antillean conger, is a common member of the conger family that can be found around the world.

They were given this name because of their sleek grey colouring, but their bellies are more white than grey in appearance. While most examples are approximately 3 feet in length, they can grow to be 5.2 feet long and weigh nearly 55 pounds.

Grey congers are found in maritime habitats that are tropical or subtropical in climate.

They can be found throughout the western central Atlantic Ocean, but they are most common around Cuba, Jamaica, and northern South America, among other places.

GREY CONGERS, which may live at depths of up to 1300 feet, are found on coral reefs and in rocky areas along the ocean floor. Finfish, as well as other bottom-feeding species, are the principal food supply for these creatures.

Even though there is a growing industry for grey conger flesh, the International Union for Conservation of Nature (IUCN) classifies them as a species of Least concern.


4). Green Moray Eel

Gymnothorax funebris is a huge species of moray eel that is one of the largest in the moray eel family. Because of the vivid greenish-yellow colour that spans the length of their bodies, they were given this name.

Green morays are easily distinguished from yellow morays based merely on their size, although they are sometimes confused with the latter.

They could grow up to 8 feet long and weigh approximately 65 lbs. Green morays can be found throughout the western Atlantic Ocean, from New Jersey to Bermuda and off the coast of Brazil and the Caribbean.

Depending on the species, they can be found in depths of up to 130 feet below sea level. They are nocturnal hunters, as are the majority of moray species. They primarily eat fish, crab, shrimp, octopuses, and squid, among other things.

According to the report of the International Union for Conservation of Nature, the green moray is a species of Least Concern.


3). Giant Moray Eel

When measured in terms of body mass, the giant moray (Gymnothorax javanicus) is the largest moray eel on the planet. However, while the slim giant moray may be the world’s longest eel, the big moray is far larger and heavier than its skinny cousin.

They can grow to be 9.8 feet long and weigh 66 pounds at their heaviest when they reach their maximum size. Large tan spots cover their brownish bodies, and the backs of their heads have two leopard-like spots, which are particularly noticeable in adults.

Giant morays can be found throughout the Indian and Pacific Oceans, including the eastern coast of Africa, the Red Sea, the Hawaiian Islands, Polynesia, Fiji, and Japan, among other places.

They can be found in lagoons and at the outer edges of coral reefs, where they thrive.

Their primary sources of nutrition are fish and crabs. Even though a few predators surround them, they will cooperate with other fish species, such as the roaming coral grouper, to look for food.

Even though they are not typically violent toward humans, they will attack if cornered or threatened. Currently, they are classified as a species of Least Concern by the International Union of Conservation of Nature.


2). American Conger

The American conger (Conger oceanicus), also known as the dog eel, poison eel, and sea eel, is one of the world’s largest eel species.

Their bodies are typically dark grey. However, their bellies are often pale in colour. From Cape Cod to northeastern Florida, American congers can be seen in large numbers in the western Atlantic Ocean.

Unlike certain eel species, they do not spend any time in freshwater during their lifetimes, even though they migrate. Although they like to reside on the ocean’s surface, you can locate them in shallow and deep water.

They primarily eat fish, molluscs, and crustaceans as their primary sources of nutrition.

Even though they have no natural predators, there is little fishing business for American conger. Because their population is vast and abundant, the International Union for Conservation of Nature (IUCN) classifies them as a species of Least Concern.


1). European Conger

The European conger (Conger conger) is the world’s largest eel by far, with a length of almost two meters. Adults are approximately 5 feet 5 inches tall and weigh approximately 159 pounds.

On the other hand, one huge specimen was 9.8 feet in length and weighed 350 pounds. They have no scales covering their bodies, and although they are usually grey, they can sometimes be blackish.

They may pose a concern to divers because of their big size and aggressive attitude. Throughout Europe, congers can be found in the eastern Atlantic off the coasts of Norway and Iceland and the Mediterranean and the Black Sea.

While sightings normally occur between 0 and 1500 feet below the ocean’s surface, when migrating to spawning areas, they can descend to depths of up to 10,000 feet below the water’s surface.

They reside in rocky outcroppings known as eel pits, and they will occasionally cohabitate with other eels if conditions are favourable.

Fish, octopuses, squid, and crustaceans make up most of their diet. Because of their widespread distribution and large population, the International Union for Conservation of Nature (IUCN) classifies these as a species of Least Concern.
