Welcome to the Ugly Animals.
Beauty is a subjective concept, and everyone has their view of beautiful things. We see beauty in almost everything, like sun, grass, trees, clouds, birds, and animals.
We love our pets and most animals around us, but certain animals are not pleasing to our eyes. For instance, a lizard is mostly considered displeasing and ugly. Similarly, there are other animals that are considered ugly by the consensus of the public. We will tell you more about the animals thought to be ugly because they are not as cute as the koalas and quokkas.
Overview of Top 10 Ugly Animals on Earth
Let’s get to know these ugly animals one by one:
#1 Purple Frog
- Scientific Name: Nasikabatrachus sahyadrensis
- Locations and Main Habitat: Forest and lakes in western India
- Average Size and Weight: 7 centimeters and 165 grams
- Average Lifespan: 1 year
- Natural Predators: deforestation and consumption of locals
Guess – who is the odd one out of the amphibians – yes! It’s a purple frog. In a world where frogs are green and brown, this one is purple. Hence, it looks hideous from the rest of the frogs. Amphibians are generally considered irksome due to their slimy skin and odd looks. However, this one takes the lead as it is rare in color and has a small head. The purple frog also has an unusually pointed snout with smaller eyes. To top it all off, the purple frog has horizontal pupils in those tiny eyes, and its body looks like a balloon filled with gas.
It looks like he realizes his ugly face as well because it spends most of its life hiding in underground burrows. It stays clung with rocks and boulders submerged in water. The purple frog lives its life by eating termites, worms, and ants. You must be wondering why purple frogs are not a common site because purple frogs come out of their hiding only for the mating season, which lasts for around two weeks.
It is primarily found in India. Due to its elongated snout, the purple frog is known with different names, like a pig-nosed frog or nose frog.
#2 Naked Mole Rat
Scientific Name: Heterocephalus glaber
Locations and Main Habitat: semi desert, East Africa
Average Size and Weight: 13 centimeters and 35 grams
Average Lifespan: 30 year
Natural Predators: Birds of prey; Snake
Some of us do not even like regular rats due to multiple reasons. Rats are unhygienic, fussy, and ugly. They are also not very friendly in general. If you can’t stand common rats, wait for a specie known as naked mole-rat. They are even more disgusting than common house rats. However, naked mole rats are not commonly found in households or populated areas as they are found in woods and deserted places.
Any hairless animal is somewhat ugly, but naked mole rats are revolting to look at. A naked mole-rat is not only seen as ugly, but it is also not protected from heat and cold due to the lack of hair on its body. The naked mole-rat is a unique creature not only because of its look but also because it does not feel any pain. Moreover, a naked mole rat does not get cancer.
A naked mole-rat has yellowish skin, which also appears pinkish at times. Its skin is also wrinkly, adding to its ugliness. Everything in its appearance is bound to make you cringe as it has thin legs, tiny eyes, and the front teeth protrude more than any other type of rat.
A naked mole-rat probably realizes that it is ugly, and that is why it spends its days living in a burrow underground in the form of groups led by a queen. Groups of naked mole rats are pretty supportive of each other, and they always work together to keep supporting the group.
Scientific Name: Lophius
Locations and Main Habitat: Northwest Atlantic Ocean
Average Size and Weight: 4,5 feet and 50 pounds
Average Lifespan: 13 year
Natural Predators: bigger fish, sharks
We have got another water creature on our list of ugly animals, and that is “the sea devil” itself. We are talking about the monkfish. Monkfish is the “naked mole-rate” of water animals. It is known for its tasty meat among many, but at the same time, it is not a pleasant-looking sea animal. Moreover, the tail of monkfish is served for a meal only because it is disgusting to look at.
It is known by many names like the sea devil or the frogfish due to its frog-like appearance and unusually repulsive face. If we talk about appearance, the monkfish has a flat, large head and eyes too small for its head. This fish’s gaping mouth and sharp teeth that point inward add to its appearance. The body is usually smaller than the head of the sea devil.
It has a large thin horn on its head known as the esca and has little spines all over its head. These help it hide in the sea as the spines look like algae or seaweed. The slimy body of monkfish is also a point in its unusually hideous appearance. However, all of this adds to its surviving abilities because it can hide under the water without having much difficulty.
#4 Proboscis Monkey
Scientific Name: Nasalis larvatus
Locations and Main Habitat: Borneo Jungle
Average Size and Weight: 70 cm and 22 kg
Average Lifespan: 20 years
Natural Predators: Crocodile, Leopard
After telling you about sea creatures and rats, let’s talk about a lesser-known creature of earth, “proboscis monkeys”. If you ask us, we are quite fond of monkeys and find them interesting and enjoyable creatures to watch. However, a type of monkey is not like the usual ones and not very pleasing to look at.
The proboscis monkey is also known as the old-world monkey. They are known with names like a long-nosed monkey, orang belanda, monyet belanda (meaning dutch monkey or Dutchman), and nasalis larvatus (scientific name). They are mostly found in riverine forests, mangroves, and swamps in Indonesia and the Southeast Asian island of Borneo. It mostly stays in lowland habitats near water.
Proboscis means long nose found in animals, and they are given this name due to their elongated nose. The male monkeys have an even longer nose than female ones, so it hangs past their mouth. They got their name based on Dutch colonizers of Indonesia, who used to have big bellies and large noses. They have long tails, and their length in total is around 21 to 30 inches.
Proboscis monkey’s diet mainly consists of flowers, fruits, seeds, leaves, bark, and insects. Therefore, they are declared as endangered species. Their lifespan is up to 25 year and they deserve their place in this list of the top 10 ugliest animals in the world.
#5 Sphynx Cat
Scientific Name: Felis catus
Locations and Main Habitat: Canada origin
Average Size and Weight: 50 cm and 6 to 12 pounds
Average Lifespan: 8 – 14 years
Natural Predators: Cars, Other Cats
Who does not love a cute kitty? Almost every one of us is a cat lover. Their cute paws and adorable nose are just too appealing to ignore. It is nearly impossible to think if there is a cat that looks ugly. However, a type of cat in this world is not so pleasant to look at. It has all the qualities of a cat, a cute nose, small paws, but it still does not make you go “aww.” We are talking about ‘sphynx cat,’ which also falls in the category of naked mole-rat.
Just like naked mole-rat, the sphynx cat is also hairless, which makes it unique as well as weird. These hairless cats were created by breeding selective hairless cats that existed due to naturally occurring genetic mutations in cats.
Sphynx cats are considered friendly (Friends fan would disagree) and therapeutic because they are warm in nature. They can be kept as a pet if you like something hairless. However, they require regular grooming, which makes these cats high maintenance.
If you ask us, we are fans of fur, and we like cats with longer fur. This is why this weird animal is on our list of the top 10 ugliest animals in the world.
Scientific Name: Hyaenidae
Locations and Main Habitat: Africa Savanna
Average Size and Weight: 37 to 59 inches and 90 to 170 pounds
Average Lifespan: 25 years
Natural Predators: Lion, Leopard
Another wildlife creature on our list of the top 10 ugliest animals is the hyena. They are undoubtedly swift predators who devour their prey. They are also known as the “jokers” of the African savannah. Hyenas are not good-looking animals and are often considered ugly. They are carnivores and are known to be brutal to their prey.
Their unusual bark and distinct eyes add a certain creepiness to their appearance. In addition, they have patchy skin and a very rough aura. Another interesting fact about hyenas is that even the king of the Jungle does not want to hunt hyenas. One of the reasons lions are not hunting hyenas is that they are not a good diet for them as hyenas are also hunters. Moreover, hyenas are also predators, and it is not easy for lions to hunt the hyenas.
Many predators in the animal kingdom do not like to eat leftovers of other predators, unlike hyenas. Therefore, they not only hunt their prey but can also dine on the leftovers of other predators. There are different species of hyenas, and all of them are known to be cunning hunters. However, they are considered intelligent animals, and hyena mothers are known to be very caring and protective of their cubs. Females mostly lead hyena clans.
Scientific Name: Psychrolutes marcidus
Locations and Main Habitat: Southwest Pacific, Deepsea
Average Size and Weight: 30cms (12 inches), 20 pounds (9 kg)
Average Lifespan: 130 years
Natural Predators: None
Yes, we are back with another sea creature known as Blobfish. This sea creature has no muscles in it and looks like a piece of slimy mess. The name suits its appearance as it is nothing but a lump of gelatin. Slimy appearance is always weird to look at, and Blobfish is no exception as it is hard to look at them and not feel revolted. Imagine a ball of slime with two eyes and a big nose, and you have the appearance of a Blobfish.
Blobfish is not very picky when it comes to food as it just swallows liquid in front of it by simply opening the mouth. Absolutely no effort is needed for a Blobfish to have its dinner. It can grow to about 12 inches long. Think about the laziest fish in the sea, and you will only have Blobfish’s name in your mind.
Blobfish are not edible. It lives in the deep places of saltwater bodies like oceans and seas. It is harder to swim in the depths of oceans, and Blobfish does it just like we float in water using a lifesaver. Pressure in the depths of the oceans is high, and swimming becomes harder, and that is why a Blobfish has less density than water. Its appearance helps to float even in the depths of the ocean without having to use much energy. The blobfish is undoubtedly a member of the top 10 ugliest animals in the world
Scientific Name: Daubentonia madagascariensis
Locations and Main Habitat: Madagascar East Cost
Average Size and Weight: 2.5 – 3.3 ft (0.7 – 1 m), 4lbs – 6lbs (2kg – 2.7kg)
Average Lifespan: 21 -23 years
Natural Predators: Birds of pray, Snakes
Meet another member of the top 10 ugliest animals in the world. No one completely knows where they got their unique name, but aye-ayes certainly got everyone’s attention. Some people think it is named after a French naturalist who showed a sign of exclamation after seeing them. Others think that they are given a name in the local language meaning “don’t know .”Whatever the case is, the aye-aye has made it o our list.
Some people even find them cute and think they are “aww-worthy” creatures, but we beg to differ. They are squirrel-like primates from Madagascar. They belong to the same family as apes and monkeys. Aye-ayes are also the largest living nocturnal primates. Most primates are known to be active during the day and not nocturnal, unlike aye-ayes.
They mostly live in the rainforests of Madagascar, but their history can be traced back to Egypt and Kenya. Their eyes are distinct features of their face that add to their ugliness.
Aye-ayes are not considered very social, and they spend most of their life solitary and arboreal. Apart from their eyes, another feature unique to aye-ayes is their long bony fingers, especially the unusually long third finger. When fully grown, they are around a foot long with their bushy tail, which is around 2 feet long. There are no distinct features to differentiate males from females except for the fact that males are slightly heavier in weight than females.
#9 Giant Salamanders
Scientific Name: Cryptobranchidae
Locations and Main Habitat: Lakes, Asia
Average Size and Weight: 60-70 cm, 5-6 kg
Average Lifespan: 30 years
Natural Predators: Hog badgers, Red foxes, Weasels
So we are back to amphibians. If you ask us, we believe all amphibians have certain repulsing qualities like frog, toad, and salamanders. Their slimy body is what makes them not-so-pleasing to look. Next, we will talk about giant salamanders, which can grow up to around 6 feet (around 1.8meters). These are found in rivers and also on land.
Giant salamanders have no eyelids adding to their ugliness with broad bodies and large heads. These have loose skin at the sides of the face. As salamanders are amphibians, they breathe through their skin. Their skin is covered in mucus. This slimy material helps the giant salamanders to keep the parasites away while on land and helps them breathe while in water.
Chinese giant salamanders have the longest life span among all amphibians. While the Japanese giant salamander, when it feels in danger, it produces a secretion that smells like Japanese pepper. All types of salamanders produce the secretion to keep the predators away from them, and the secretion works effectively except for humans.
Salamanders are usually carnivorous and eat different animals like crayfish, snails, small mammals, insects, and fish. They have a slower metabolism and are known to go without eating, even for weeks. Salamanders are also known to have poor eyesight, so they rely on vibrations in the water to hunt their prey. They have incredible regenerative capabilities, and they can re-grow skin and bone.
Scientific Name: Tetraodontidae
Locations and Main Habitat: Tropical and Subtropical Oceans
Average Size and Weight: 2 feet, 30 pounds
Average Lifespan: 10 years
Natural Predators: Sharks, Bigger Fish
Yet another member of the top 10 ugly animals in the world and we are back to sea creatures, and the next animal on our list of ugly animals is another fish. These have usually rounded heads, tapered bodies, large stomachs, and prominent lips. Pufferfish do not have scale on the skin but have spines all over. Like Blobfish, they are also considered lazy as they swim slower, but unlike Blobfish, they can pick up speed when required. Pufferfish can also swim backward also and change directions easily.
Pufferfish are known by multiple names like blowfish, swellfish, toadfish, puffers, globefish, and balloon fish. It can inflate itself with air or water and become almost globular in form. For example, blowfish inflates itself when it is disturbed or feels threatened. Even though it has spines over, it should not be confused with porcupinefish, which is a member of a different family.
Pufferfish belongs to the family of Tetraodontidae, and it has 120 species in 19 different genera. It is mostly found in tropical waters all across the world. Pufferfish are found in both saltwater as well as freshwater bodies. It is found in the Red Sea and the Pacific Ocean, along with the Amazon, Mekong Rivers, and estuaries of freshwater bodies. Pufferfish are usually small, but the largest one can grow about 90 centimeters (around 3 feet) long.
All pufferfish produce a substance known as tetrodotoxin, making them foul-tasting and mostly lethal to other fish who wish to eat them. Moreover, it is also extremely poisonous to humans as it is 1200 times more poisonous than cyanide. Pufferfish are so deadly that one pufferfish can kill 30 human adults, and also there is no antidote known so far. However, the Japanese have found a way to cook puffers where they cleaned these carefully by a trained chef and cooked to eat. Only highly trained and licensed chefs are allowed to cook puffers. Still, many deaths occur annually. They are considered a sophisticated food in Japan known as fugu.
