The 10 Most Unattractive Creatures

This list focuses solely on external appearances, not inner qualities, so avoid mentioning your most despised political figures or celebrities (I know you might be tempted). Also, insects are excluded – they belong to an entirely different level of unattractiveness! Starting from the least off-putting to the most repulsive, here are nature's top 10 ugliest creatures.

10. Mata Mata

The mata mata is a freshwater turtle predominantly found in South America, mainly in the Amazon and Orinoco river basins. Its strikingly unique appearance sets it apart from other turtles. This creature excels in hunting techniques. The French naturalist, Pierre Barrère, described it in this way:

“A large land turtle covered in spiky, ridged scales.” The mata mata is easily recognizable: its head is large, triangular, and extremely flat, adorned with tubercles and folds of skin, including a distinctive 'horn' on its nose. It also has two barbels on its chin and two more filamentous barbels on its jaw. Its snout is long and tube-shaped, and its upper jaw is neither hooked nor notched.

Horseshoe bats (family Rhinolophidae) consist of around 130 species spread across 10 genera. All members of this family feature leaf-shaped protrusions on their noses. In the rhinolophine species, these resemble horseshoes, while in the hipposiderine species, they appear as leaf- or spear-like structures. These bats use these formations to emit echolocation calls, which help focus the sound. Most horseshoe bats are dull brown or reddish-brown in color and range in size from small to moderately large.

The Star-Nosed Mole is a small North American species found in eastern Canada and the northeastern United States. It thrives in wet lowland environments, feeding on small invertebrates, aquatic insects, worms, and mollusks. Known for its swimming abilities, it can forage at the bottoms of streams and ponds. Like other moles, it creates shallow surface tunnels for hunting, often leading to underwater exits. This creature is active both day and night and continues to function in winter, having been seen tunneling through snow and swimming in ice-covered streams.

Sloths are medium-sized mammals native to Central and South America. They are omnivorous, feeding on insects, small lizards, carrion, but primarily on buds, tender shoots, and leaves. Sloth fur has unique features: their outer hairs grow in the opposite direction of most mammals. While most mammals have hair growing toward their extremities, sloths’ hair grows away from the extremities, providing protection from the elements as they hang upside down.

The Naked Mole Rat, also known as the Sand Puppy or Desert Mole Rat, is a burrowing rodent found in parts of East Africa. Typical individuals range from 8 to 10 cm in length and weigh between 30 and 35 g, while queens are larger and can weigh more than 50 g, with some reaching up to 80 g. They are perfectly suited to life underground, with narrow slit-like eyes and poor vision. However, they are incredibly agile underground, able to move as quickly backward as forward. Their large, protruding teeth are used for digging, and their lips seal behind the teeth to prevent soil from entering their mouths. They have short, thin legs, very little hair, and wrinkled pink or yellowish skin.

The Axolotl, also known as ajolote, is the most famous of the Mexican neotenic mole salamanders, which are part of the Tiger Salamander complex. Unlike most species, the larvae of this salamander do not undergo metamorphosis, meaning that the adults remain aquatic and retain gills. Their heads are wide, and their eyes lack eyelids. Their limbs are underdeveloped, with long, thin digits. Axolotls also have vestigial teeth that would have appeared during metamorphosis, though they are barely visible. They primarily feed by suction, during which their rakers interlock to close their gill slits. Axolotls come in four colors: two naturally occurring, and two mutants. The two natural colors are wildtype (brown shades with spots) and melanoid (black). The mutant colors are leucistic (pale pink with black eyes) and albino (golden, tan, or pale pink with pink eyes).

Tarsiers are small primates of the genus Tarsius, known for their large eyes and long feet. Their feet have exceptionally long tarsus bones, which is the reason behind their name. These insectivores capture their prey by leaping at it. Tarsiers are also known to hunt birds and snakes. As they leap from tree to tree, they can even capture flying birds mid-air. In captivity, tarsiers have not been able to breed successfully, and they have been known to harm or even kill themselves due to the stress of being caged.

Despite their name, there's ongoing debate over whether Hagfish should truly be classified as fish, since they belong to a much more primitive lineage than most groups typically categorized as fish. Hagfish are long, worm-like creatures that can produce vast amounts of sticky slime or mucus. When captured by the tail, they escape by secreting this fibrous slime, which becomes a thick, sticky gel upon contact with water. They then clean themselves by tying their body in an overhand knot, which works its way from head to tail, scraping off the slime as it goes. Hagfish possess eel-like bodies and paddle-shaped tails.

The Aye-aye is a unique creature native to Madagascar, possessing rodent-like teeth and an unusually long, thin middle finger, which it uses in a similar manner to a woodpecker for foraging. As the largest nocturnal primate on Earth, the Aye-aye spends much of its time in the forest canopies. Adult Aye-ayes have dark brown or black fur, with white guard hairs around the neck, and a bushy tail reminiscent of a squirrel’s. The face is similarly rodent-like, resembling that of a raccoon, with bright, expressive eyes. Its large incisors grow continuously throughout its life.

The Blobfish is found in the deep waters off the coasts of Australia and Tasmania, where it remains rarely seen by humans due to its remote habitat. These fish live at depths where the pressure is several dozen times greater than at sea level. To maintain buoyancy, the Blobfish’s flesh is mainly a gelatinous substance, with a density slightly less than water, allowing it to float above the sea floor without expending much energy. The lack of muscle mass is not a disadvantage for the Blobfish, as it feeds by simply swallowing the edible matter that floats past.
