Beauty is subjective. What’s attractive in one culture could be gross in another. But alas, there are some species that don’t rank in any society. To that end, here’s our list of the 10 ugliest animals on Earth.

#10 Ugliest Animal: Naked Mole-Rat

Naked mole-rats are blind rodents that live in underground colonies. But their names are a misnomer because the subterranean dwellers are neither moles nor rats. Instead, they’re most closely related to guinea pigs, porcupines, and chinchillas.

To be fair, naked mole-rats aren’t even fully nude. Individuals don about 100 hairs over their bodies that serve as navigation whiskers. And though they may not be the most pulchritudinous specimens in Mother Nature’s menagerie, they live longer than any other rodent and are nearly immune to cancer.

#9 Ugliest Animal: Blobfish

With their slimy bodies and unbalanced features, blobfishes define what humans consider ugly. The deep-sea fish live around the Antipodes, and scientists first classified them in 1926. However, since they dwell in remote regions, blobfishes weren’t known to the public. That all changed in 2003 when several were caught in an expedition.

Since 2013, the blobfish has topped the Ugly Animal Preservation Society’s ranking of ugliest animals in existence.

#8 Ugliest Animal: Monkfish

Known as the “poor man’s lobster” and sometimes called “sea-devils,” monkfish have large, flat heads, wide mouths, and comparatively little bodies. Their eyes are small and beady, and individuals exude a generally slimy vibe that’s less than attractive.

But monkfish probably couldn’t care less about our aesthetic sensibilities. After all, their unique looks keep them well camouflaged in deepwater dwellings — and being alive is more important than being pretty!

#7 Ugliest Animal: Hyena

“Jokers” of the African savannah, hyenas are scraggly carnivores with a distinct bark that heightens their creepiness. Hyenas are notoriously rag-tag, and their patchy hair adds to their disheveled aura. But you can’t accuse hyenas of being wasteful. Like a survivalist hunter who shuns waste, hyenas devour every inch of their prey.

#6 Ugliest Animal: Warthog

Sure, their odd-shaped heads and large snouts aren’t exactly attractive. However, what lands warthogs on our ugliest animals list is the fleshy “warts” that cover their bodies. But the bumps aren’t actually warts. Instead, they’re built-in armor that protects the wild pigs during combat.

#5 Ugliest Animal: Aye-Aye

Beauty, they say, is in the eye of the beholder. And undoubtedly, some people “ooh and aww” over aye-ayes. But to us, the tiny primates look like unfortunate gremlins. And their bug-eyed faces aren’t solely to blame. They also have long, bony fingers like the Wicked Witch of the West, long fangs, and huge ears.

#4 Ugliest Animal: Matamata Turtle

In Spanish, its name means “kill! Kill!” And if you stumbled upon a matamata turtle, that may be your immediate reaction. After all, the species is uncomfortably odd looking! Its long, wart-filled neck protrudes from an unattractive shell, culminating in a flat head that’s accented with an unfortunate nose.

But as is the case with so many ugly animals, the matamata’s off-putting exterior makes it one of the most vicious predators in its habitat. Not only do they blend in perfectly with their swampy surroundings, but their long necks allow for a generous snapping range that’s ideal for hunting.

#3 Ugliest Animal: Fruit Flies

To the naked eye, fruit flies are just faceless, swarming dots. But underneath the microscope, their displeasing visages are amplified. Big red eyes dominate their faces, and bedraggled hair whiskers are scattered across their crowns. The combination equals one thing: ugly!

#2 Ugliest Animal: Vultures

The whole vulture package is unpleasant. Not only do the large birds spend their days picking over rotting meat, but they smell, and their faces seem to exude evil. Their heads are long and wrinkly, and many have grotesque appendages and waddles hanging from their necks. Dainty, pretty hummingbirds they are not!

#1 Ugliest Animal: Bedlington Terriers

It’s tough to find an ugly dog breed, but Bedlington Terriers fit the bill. The mid-sized canines are loyal and love to frolic, but they don’t rank high on looks. For starters, their bodies have a strained profile. Secondly, their snouts are long and narrow. Occasionally, with the right grooming, a Bedlington Terrier can look regal. But let’s face it, even when it comes to human royalty, regal rarely amounts to good-looking.
