Top 26 Strangest Animals

This list doesn’t focus on an animal’s ‘ugliness’, but on their strange and unusual characteristics. Some have been around for hundreds or even thousands of years, but they may be new to you. Of course, it’s hard to choose just ten of the world’s bedazzling and bewildering beasts to turn the spotlight on, so be sure to mention your favorites in the comments.

White-faced Saki Monkey: The White-faced Saki (Pithecia pithecia), also known as the Guianan Saki and the Golden-faced Saki, is a species of saki monkey, a type of New World monkey, found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. This monkey mostly feed on fruits, but also nuts, seeds, and insects.

Yeti Crab: Kiwa hirsuta is a crustacean discovered in 2005 in the South Pacific Ocean. This decapod, 6 inches long, is notable for the quantity of silky blond setae (resembling fur) covering thoracic legs and claws. Its discoverers dubbed it the “yeti lobster” or “yeti crab”. Based on both morphology and molecular data, the species was deemed to form a new genus and family (Kiwaidae). The animal has strongly reduced eyes that lack pigment, and is thought to be blind. The ‘hairy’ pincers contain filamentous bacteria, which the creature may use to detoxify poisonous minerals from the water emitted by the hydrothermal vents where it lives. Alternatively, it may feed on the bacteria, although it is thought to be a general carnivore. Its diet also consists of green algae and small shrimp.

Vampire squid: The Vampire Squid is a small, deep-sea cephalopod found throughout the temperate and tropical oceans of the world. With their long velar filaments deployed, Vampire Squid have been observed drifting along in the deep, black ocean currents. If the filaments contact an entity, or if vibrations impinge upon them, the animals investigate with rapid acrobatic movements. They are capable of swimming at speeds equivalent to two body lengths per second, with an acceleration time of five seconds. However, their weak muscles limit stamina considerably.

Tasmanian Tiger: The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It is commonly known as the Tasmanian Tiger (due to its striped back), the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger. It was the last extant member of its genus, Thylacinus, although a number of related species have been found in the fossil record dating back to the early Miocene. The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania along with a number of other endemic species, including the Tasmanian Devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite being officially classified as extinct, sightings are still reported.

Tasmanian Devil: The Tasmanian devil is a carnivorous marsupial now found in the wild only in the Australian island state of Tasmania. Because they were seen as a threat to livestock in Tasmania, devils were hunted until 1941, when they became officially protected. Since the late 1990s, devil facial tumour disease has reduced the devil population significantly and now threatens the survival of the species, which in May 2009 was declared to be endangered.


Sumatran rhino: The Sumatran Rhino is a mostly solitary animal except for courtship and child-rearing. It is the most vocal rhino species and also communicates through marking soil with its feet, twisting saplings into patterns, and leaving excrement. The rhino spends a large part of its day in wallows. When mud holes are unavailable, the rhino will deepen puddles with its feet and horns. The wallowing behavior helps the rhino maintain its body temperature and protect its skin from ectoparasites and other insects.


Solenodon: Solenodons are venomous, nocturnal, burrowing, insectivorous mammals belonging to the family Solenodontidae. Only one genus, Solenodon, is known, although a few other genera were erected at one time and are now regarded as junior synonyms. The Solenodontidae family is interesting to phylogenetics researchers due to its retention of primitive mammal characteristics; their species resemble very closely those that lived near the end of the age of the dinosaurs.


Sea pig: Sea pigs are also known as scotoplanes, a genus of deep-sea holothurians (sea cucumbers). This sea creature is like a cross between a pig and a slug. I still think it’s cute, despite the fact that it looks like it has human fingers growing out of its mouth.

São Tomé Shrew: The São Tomé Shrew (Crocidura thomensis) is a white-toothed shrew found only on São Tomé Island, São Tomé and Príncipe. It is listed as a critically endangered species due to habitat loss and a restricted range.

Platypus: The Platypus is a semi-aquatic mammal endemic to eastern Australia. Together with the four species of echidna, it is one of the five mammals that lay eggs instead of giving birth to live young. The bizarre appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some considering it an elaborate fraud. It is one of the few venomous mammals; the male Platypus has a spur on the hind foot, which delivers a poison capable of causing severe pain to humans. The unique features of the Platypus make it an important subject in the study of evolutionary biology and a recognizable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of the Australian 20 cent coin.


Star-nosed Mole: The Star-nosed Mole (Condylura cristata) is a small North American mole found in eastern Canada and the north-eastern United States. It is the only member of the tribe Condylurini and the genus Condylura.It lives in wet lowland areas and eats small invertebrates, aquatic insects, worms and molluscs. It is a good swimmer and can forage along the bottoms of streams and ponds. Like other moles, this animal digs shallow surface tunnels for foraging; often, these tunnels exit underwater. It is active day and night and remains active in winter, when it has been observed tunnelling through the snow and swimming in ice-covered streams. Little is known about the social behavior of the species, but it is suspected that it is colonial.The Star-nosed Mole is covered in thick blackish brown water-repellent fur and has large scaled feet and a long thick tail, which appears to function as a fat storage reserve for the spring breeding season. Adults are 15 to 20 cm in length, weigh about 55 g, and have 44 teeth. The mole's most distinctive feature is a circle of 22 mobile, pink, fleshy tentacles at the end of the snout. These are used to identify food by touch, such as worms, insects and crustaceans.

Narwhal: The Narwhal is an Arctic species of cetacean. It is one of two species of white whale, the other being the Beluga whale. The most conspicuous characteristic of male narwhal is their single extraordinarily long tusk, an incisor that projects from the left side of the upper jaw and forms a left-handed helix. The tusk can be up to nearly 10 feet long and weigh up to 22 pounds. About one in 500 males has two tusks, which occurs when the right tooth, normally small, also grows out. The purpose of the tusk has been the subject of much debate. Early scientific theories suggested that the tusk was used to pierce the ice covering the narwhal’s Arctic Sea habitat. Others suggested the tusk was used in echolocation. More recently, scientists believed the tusk is primarily used for showmanship and for dominance: males with larger tusks are more likely to successfully attract a mate.

Mola mola aka Ocean Sunfish: The ocean sunfish, Mola mola, or common mola, is the heaviest known bony fish in the world. It has an average adult weight of 1,000 kg. Sunfish live on a diet that consists mainly of jellyfish, but because this diet is nutritionally poor, they consume large amounts in order to develop and maintain their great bulk. Females of the species can produce more eggs than any other known vertebrate. Sunfish fry resemble miniature pufferfish, with large pectoral fins, a tail fin and body spines uncharacteristic of adult sunfish.

Long-beaked echidna: The long-beaked echidnas make up one of the two genera (genus Zaglossus) of echidnas, spiny monotremes that lives in New Guinea. There are three living species and two extinct species in this genus. Echidnas are one of the two types of mammals that lay eggs.

Leafy Sea-dragon: Named after the dragons of Chinese mythology, Leafy Sea-dragons resemble a piece of drifting seaweed as they float in the seaweed-filled water. The Leafy Sea-dragon, with green, orange and gold hues along its body, is covered with leaf-like appendages, making it remarkably camouflaged. Only the fluttering of tiny fins or the moving of an independently swiveling eye reveals its presence. Sea-dragons have no teeth or stomach and feed exclusively on mysidopsis shrimp. Known as “Australian seahorses” in Australia, they are found in calm, cold water that is approximately 50-54° Fahrenheit. The South Australian government since 1982 has protected Leafy Sea-dragons.

Pangolin: A pangolin, also scaly anteater or tenggiling, is a mammal of the order Pholidota. Pangolins have large keratin scales covering their skin and are the only mammals with this adaptation. They are found in tropical regions of Africa and Asia. The name “pangolin” derives from the Malay word pengguling (“something that rolls up”). Pangolins are nocturnal animals, and use their well-developed sense of smell to find insects. The long-tailed pangolin is also active by day. Pangolins spend most of the daytime sleeping, curled up into a ball.

Frill-necked Lizard: The Frill-necked Lizard, also known as the Frilled Dragon, is so called because of the large ruff of skin which usually lies folded back against its head and neck. Long spines of cartilage support the neck frill, and when the lizard is frightened, it opens its mouth showing a bright pink or yellow lining, and the frill flares out, displaying bright orange and red scales. They often walk on four legs when on the ground. When frightened they begin to run on all fours and then accelerate onto the hind-legs. The frill of the Australian frilled dragon is used to frighten off potential predators, as well as hissing and lunging.

Dumbo Octopus: The octopuses of the genus Grimpoteuthis are also known as “Dumbo octopuses” from the ear-like fins protruding from the top of their “heads” (actually bodies), resembling the ears of Walt Disney’s flying elephant. They are benthic creatures, living at extreme depths, and are some of the rarest of the Octopoda species. They can flush the transparent layer of their skin at will, and are open ocean animals, unlike most octopi.

Coelacanth: Coelacanth is the common name for an order of fish that includes the oldest living lineage of jawed fish known to date. The coelacanths, which are related to lungfishes and tetrapods, were believed to have been extinct since the end of the Cretaceous period, until the first specimen was found off the east coast of South Africa, off the Chalumna River in 1938. Since 1938, they have been found in the Comoros, Kenya, Tanzania, Mozambique, Madagascar, among other places. Coelacanths first appear in the fossil record in the Middle Devonian, about 410 million years ago. Coelacanths are lobe-finned fish with the pectoral and anal fins on fleshy stalks supported by bones, and the tail or caudal fin diphycercal (divided into three lobes), the middle one of which also includes a continuation of the notochord.

Axolotl: The Axolotl (or ajolote) (Ambystoma mexicanum) is the best-known of the Mexican neotenic mole salamanders belonging to the Tiger Salamander complex. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. The species originates from the lake underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate most body parts, ease of breeding, and large embryos. They are commonly kept as pets in the United States, Great Britain, Australia, Japan (where they are sold under the name Wooper Rooper, and other countries.Axolotls should not be confused with waterdogs, the larval stage of the closely related Tiger Salamanders (Ambystoma tigrinum and Ambystoma mavortium), which is widespread in much of North America which also occasionally become neotenic, nor with mudpuppies (Necturus spp.), fully aquatic salamanders which are unrelated to the axolotl but which bear a superficial resemblance.

Greater Galago: The greater galagos or thick-tailed bushbabies are the common name for three species of strepsirrhine primates. They are classified in the genus Otolemur in the family Galagidae.

Anglerfish: Anglerfish are named for their characteristic mode of perdition, wherein a fleshy growth from the fish’s head (the esca) acts as a lure. Anglerfish also have spines protruding from their head, movable in all directions. The esca can be wiggled so as to resemble a prey animal, and thus to act as bait to lure other predators. Deep-sea anglerfish live mainly in the oceans’ aphotic zones, where the water is to deep for the sun to penetrate; therefore their perdition relies on the “lure” being bioluminescent. Since individuals are presumably locally rare and encounters doubly so, finding a mate is problematic. When scientists first started capturing ceratioid anglerfish, they noticed that all of the specimens were females. These individuals were a few inches in size and almost all of them had what appeared to be parasites attached to them. It turned out that these “parasites” were the remains of male ceratioids.

Amazon River Dolphin aka Boto: The Amazon River Dolphin, alternately Bufeo, Bufeo Colorado, Boto, Boto Cor de Rosa, Boutu, Nay, Tonina, or Pink River Dolphin, is a freshwater river dolphin endemic to the Orinoco, Amazon and Araguaia/Tocantins River systems of Brazil, Bolivia, Peru, Ecuador, Colombia and Venezuela. Because they are unfused, the neck vertebrae of the Amazon River Dolphin are able to turn 180 degrees. The pink dolphin has been listed as endangered by the International Union for Conservation of the Nature due to pollution, over fishing, excessive boat trafficking and habitat loss. The brain of the river dolphin is 40% larger than a human brain.

African Civet: The African Civet is a common viverrid native to tropical Africa. Unlike many other members of the family, which resemble cats, the African Civet resembles a short dog-like animal. Like all civets it has perianal glands that produce a fluid known as civetone (used in the perfume industry), which it spreads on markers in its territory to claim its range.

Aardvark: The Aardvark is a medium-sized, burrowing, nocturnal mammal native to Africa. The aardvark is nocturnal and is a solitary creature that feeds almost exclusively on ants and termites; the only fruit eaten by aardvarks is the aardvark cucumber. Aardvarks can live to be over 24 years old in captivity.

Angora Rabbit: The Angora rabbit is a variety of domestic rabbit bred for its long, soft hair. The rabbits were popular pets with French royalty in the mid 1700s, and spread to other parts of Europe by the end of the century. They are bred largely for their long wool, which may be removed by shearing or plucking (gently pulling loose wool).
