9 Ugliest Fishes In The World That You Will Ever See

Are you curious about the Ugliest Fishes In The World or trying to locate the most repulsive fish on earth? Although nature is magnificent, not all marine animals are as cute as clownfish or as beautiful as killer whales. Although every living thing is essential and has a function, evolution occasionally results in a creature that does not meet the standards of beauty set by humans.

Yet, because beauty and ugliness are primarily arbitrary, relative concepts, we have chosen a variety of fish species to demonstrate how awful nature can get without employing any scientific methodology. A photo accompanies each fish on the list below as evidence, and they are not included in any particular order.

Ugliest Fishes In The World

There are so many different kinds of marine life that it’s hard to even begin to imagine them all, and many beautiful fish species are simply unimaginable. The following list of the ugliest fish features species that have some of the most bizarre appearances and are guaranteed to shock and horrify you.


Monkfish, sometimes called goosefish, sea devils, fishing frogs, and anglers, are members of the Lophiidae family of fish. Mottled skin, a big head and mouth, small eyes, and teeth that mimic fangs make monkfish among the ugliest fish in the water.

They devour anything that is offered to them and is also voracious eaters. The head is enormous, broad, flat, and hollow, while the body seems hardly more than an appendage. Bands of long, angular teeth that can be momentarily inhibited are on both jaws.


This prevents an object from escaping from the mouth while offering the least resistance to an object going toward the stomach. The largemouth wraps the anterior head circumference.

The fish’s pectoral and ventral fins can act as feet, allowing it to move around on the ocean floor, where it usually hides in the sand or among the seaweed. Its head and torso are covered in fringed appendages that resemble short seaweed fronds.

With the capacity to change the colour of its body to blend in with its surroundings, the fish dramatically benefits from these traits to conceal itself in its hiding places. They typically pick hiding places where their favoured prey is concentrated in large numbers.

Despite its disgusting, ghastly appearance, the monkfish is a delicious sea creature. It is indigenous to the Northwest Atlantic Ocean, and Japan values its liver highly.

Goblin Shark 

The Goblin Shark is one of today’s rarest sharks and lives in deep ocean waters. It is a voracious animal with a long, elongated snout and an oddly shaped mouth.

Often, fish referred to as “goblin sharks” live on the ocean floor near continental shelves or the edges of continents. These pink monsters have a maximum length of 12 feet and a weight of 460 pounds. They have slender snouts and teeth that mimic fangs. They typically live off the coast of Japan.

Goblin Shark

Its likeness to mythical goblins that appear in Japanese folklore gave rise to the name. On the behaviour of these rarely met animals, biologists know relatively little. However, they believe that goblin sharks, like many other shark species, live alone. According to their theory, fish are the first and last active at night.

Since these creatures are probably slow-moving, finding food may be difficult. Thankfully for the slowpokes, their unusually elongated jaws allow them to take more meals.

Atlantic Wolffish

The Atlantic Wolffish, often known as the sea wolf or the devilfish, has a hideous appearance. It hunts slow-moving prey, including crabs, lobsters, sea urchins, and enormous marine snails with its projecting canine-like teeth.

Wolf fishes are easily distinguished from other fish species by the size of their eggs and the natural antifreeze they make to keep their blood flowing freely in their freezing home, in addition to their unusual look. In contrast to most species, both the male and female actively take part in raising the brood.

Atlantic Wolffish

They are essential in controlling the numbers of sea urchins and green crabs, which, if left unchecked, might significantly disturb the habitat. A key gauge for the health of other populations of bottom-dwellers, including the Atlantic cod population, is the population of Wolffish.

The common bycatch of the Atlantic wolffish, bottom trawlers pose a threat to it. The Atlantic wolffish eats echinoderms, crabs, and hardshell molluscs with the help of its strong jaws. They do not eat other fish.

They are reported to regularly eat large whelks (Buccinum), cockles (Polynices, Chrysodomus, and Sipho), sea clams (Mactra), enormous hermit crabs, starfish, and sea urchins. In addition, they are a significant predator of green crabs and sea urchins, whose proliferating numbers, if not controlled, could undermine the stability of a marine ecosystem.

Sloane’s Viperfish

Sloane’s Viperfish is a dragonfish that lives in temperate and tropical seas worldwide. It primarily consumes crustaceans and tiny fish and has a long dorsal spine. The Sloane’s viperfish, sometimes known as the viperfish, can be identified by its long, needle-shaped teeth and peculiar lower jaw.

They usually range from 12 to 23 inches (30 to 60 centimetres). Viperfish live in the tropics and deep ocean areas (3,300 to 16,000 feet). The average water temperature at this site is 39°F.

They are one of many fish on this list that can lure prey using photophores or other light-producing structures. They are located along the edges of the body and close to the dorsal fin spine’s tip—the light of the viperfish flashes on and off like the anglerfish.

Viperfish are a species of fish that range in color from green to black and are thought to be able to live up to 40 years in the wild. These appear to have scale-like objects, although exactly what they are is unclear. Whatever it is, they are unquestionably in the top ten fish in terms of appearance.


The Hagfish is an eel-shaped marine species that dwell on the ocean floor and inhabits frigid, deep seas all over the planet. Although almost entirely blind, hagfish have highly developed senses of touch and smell.

They have four pairs of sensing tentacles surrounding their mouth. A hagfish’s mouth contains a tongue-like extension on top of two pairs of rasps that mimic teeth but no jaws.


As its tongue is pulled back into the hagfish’s mouth, the pairs of rasps pincer. Its bite assists in gathering and consuming marine invertebrates and tearing into the flesh of fish that have fallen to the muddy ocean floor and died.

Although the hagfish may go up to seven months without feeding due to their slow metabolism, polychaete worms comprise the most significant part of their diet. This strange-looking fish, also known as a slime eel, can spit out multiple litres of slime at once, which it uses to fend off predators and make a quick getaway.

Another peculiar characteristic of this species is its capacity to feast on dead fish or other dying marine life by burrowing deep into their flesh and devouring their meals from the inside out.

Most people in the world do not consume Hagfish. But the hagfish is a treasured delicacy in Korea. It is usually peeled, doused with fiery sauce, and stir-fried or roasted over coals. It is trendy in cities along the South Gyeongsang Province’s coastline and southern port cities like Busan.

The majority of hagfish that are harvested for food around the world are sold to South Korea and Japan. Hagfish slime is frequently used as an alternative to tofu since it does not require heating and can bind a significant amount of liquid even at shallow temperatures.

Whitemargin Stargazer

The Whitemargin Stargazer is a member of the family of stargazers, and it has eyes and lips that face upward on the top of its head. They can shock animals with electricity via their electroplates, which aids their hunting ability. In addition to being among the ten ugliest fish, they are also among the most vicious fish and should not be taken lightly.

They have double-grooved poison spines behind the operculum and above the pectoral fins, and wounds can be fairly serious. Stargazers have electric organs in a special pouch below their eyes that may discharge up to 50 volts depending on the temperature of the water!

Whitemargin Stargazer

Stargazers have earned the moniker “the meanest things in existence” because they ambush predators that hide, some of which can deliver venom and electric shocks. The fish is known as “mother-in-law fish” in the area.

It can be challenging to spot because it usually spends most of its time submerged in the bottom, with only the eyes protruding, and lives in reef flats. While they breathe when buried, the cirri on the mouth’s edge keep sand out. To bring the prey within mouth-striking distance, the oral lure is used.

Red-Lipped Batfish

The Red-lipped Batfish, another bottom-dweller found in the waters near the Galapagos Islands, is an unusual fish that would be an understatement. They deserve to be among the top ten fish on this list of the ugliest fish.

The fish has an eye-catching bright red pout, a beard, and a moustache, giving it a unique appearance. It could be hard for some people to believe this strange aquatic creature isn’t wearing makeup! As it reaches sexual maturity, its modified dorsal fin draws prey such as tiny fish, shrimp, and crabs.

Red-Lipped Batfish

Unlike other fish species in the ocean, the red-lipped batfish utilizes its pectoral and pelvic fins to ‘walk’ on the seafloor. It is a genuinely awkward swimmer. Depending on who you ask, the red-lipped batfish is either ugly or merely odd-looking.

The red-lipped batfish, found near the South American coast in Peru and the Galapagos Islands, has an interestingly shaped body. Specialists say this body shape may help the fish find a spouse.

Unlike most fish, red-lipped batfish prefer to “walk” on the ocean floor instead of swimming gracefully. Its dorsal fin is no longer used for swimming as they age; instead, it is used to entice prey.

Angler Fish

The second-ugliest fish on the list is the Angler Fish, a furious-looking creature that lives at the bottom of the Antarctic and Atlantic oceans. Many people consider it one of the ugliest animals on Earth and a hideous marine species.

Its most distinctive feature, a portion of the dorsal spine that sticks out above the lips like a fishing pole and gives origin to its name, is only present in females. When prey approaches close enough to be drawn in by its luminous flesh, this built-in rod snaps it up.

Angler Fish

Because of their vast jaws and their bodies’ flexibility, they can swallow prey up to double their size. The Angler Fish has a massive head, a mouth shaped like a giant crescent, and pointed clear teeth. Angler fish are often dark grey to dark brown. Certain angler fish can reach enormous sizes of up to 3.3 feet. The majority are notably smaller and frequently less than a foot tall.

Frilled Shark

One of the oldest sharks is the frilled shark, a living fossil found in the murky depths of the Atlantic and Pacific oceans. These sharks have elongated bodies that resemble eels, and their 300 needle-sharp teeth allow them to lunge and bend swiftly to catch prey.

The frilled shark’s snake-like head and enormous jaws, which are big enough to allow them to eat whole food, are two more distinguishing features. The two six-gill apertures on either side of the body and behind the head have a characteristic frilly edge.

Frilled Shark

The front slits on each side cross beneath the body close to the throat, creating the appearance of a collar. A little dorsal fin can be seen on the body’s very rear. The body is dark brown or grey and has short, paddle-shaped pectoral fins and a large anal fin.

The lower lobe of the caudal fins is small and underdeveloped. The serpentine body, on the other hand, is noticeably lengthened and expanded by the higher lobe.
