Often weighing in at more than 10 kilograms (22 lbs), the Flemish Giant is by far the largest rabbit breed in the world. They are also extremely docile creatures and make great pets.

Originally a utility breed raised in Flanders, Belgium for its fur and meat, the Flemish Giant eventually became a show breed, due to its high bone-to-meat ratio. Today, they are considered one of the most docile and tolerant rabbit breeds in the world and can make great pets, if raised correctly. According to breed standards, a well-developed Flemish Giant has a large head, long, erect ears, a long and powerful body, and a nicely rounded rump. Unsurprisingly, the world’s largest rabbit is a Flemish Giant rabbit that weighs 49 lb (22 kg) and measures 1.3 m (4 ft 3 in).

Japanese clothing and housewares company Nissen recently launched its most intriguing product yet – a line of bed linens and blankets that try to mimic cat fur.

Studies have shown that petting a cat for just 10 minutes reduces the levels of stress hormones, and any cat lover will tell you just how relaxing the experience can be. But what about people who would love to have a pet cat, but are living in rented apartments that don’t allow pets? Or how about people who are allergic to cats, what are they supposed to do to relax? Well, that’s where the new Neko Feel (“Cat Feel”) material developed by Nissen comes into play. The Japanese company just launched a line of bed Neko Feel linens that it claims mimics the feel of cat fur.

Lorikeet Paralysis Syndrome (LPS) is a seasonal disease that occurs every year between October and June, causing lorikeets to drop out of the sky and become unable to move.

Ornithologists and veterinarians have known about Lorikeet Paralysis Syndrome for many years now, but despite their best efforts, the cause of the disease has remained a mystery. That is particularly alarming because the disease affects thousands of birds every year, and proves fatal to many of them, rendering them unable to feed or escape predators. Cases of LPS have been reported in Australia since 1970, and although scientists have been able to eliminate some probable causes, they still don’t know what causes it.

An 18-year-old lioness has baffled staff at a zoo in Kansas after growing an “awkward teenage mane” after the pride’s last male lion passed away.

Looking at Zuri, you’d think she was a young lion growing his mane for the first time, but she is actually an 18-year-old female. That makes the mane around her neck pretty unusual, with only a handful of similar cases reported in the past. The lioness reportedly started growing a mane soon after the last male lion at Topeka Zoo in Kansas passed away in October of 2020. Although zookeepers don’t believe there is any connection between the lack of a male lion and Zuri’s mane, they do admit that the lioness has gotten feistier since growing the new fur, growling, snarling, and roaring more often than before.

A 33-year-old gorilla who has spent most of her life alone inside a metal cage on the seventh floor of a shopping mall in Bangkok, Thailand, has been dubbed the world’s loneliest gorilla.

Bua Noi was only one when she was put into the cage that would become her permanent home for more than three decades. She was one of the main attractions of a bizarre zoo – if one could even call it that – inside Bangkok’s oldest shopping mall, Pata Pinklao Department Store, and owners refused to relocate her to a more suitable location, despite numerous requests from animal rights activists and the Thai Government. Even today, Bua Noi’s owners refuse to let her live out the rest of her days in a sanctuary, with other members of her species.

Researchers have discovered that green tree frogs in the Chernobyl Exclusion Zone have turned dark in order to better mitigate the effects of radiation.

In April of 1986, a reactor at the Chernobyl nuclear power plant in Ukraine exploded, releasing approximately 100 times the energy released by the nuclear bombs of Hiroshima and Nagasaki and drastically altering the lives of both humans and wildlife in the surrounding area. But while authorities were able to evacuate most civilians from the area closest to the nuclear disaster, the animals were left to their own devices. In the decades since, the Chernobyl Exclusion Zone has become a wildlife refuge that offers a unique view into the evolution triggered by the nuclear meltdown.

Kitti’s hog-nosed bat, also known as the Bumblebee Bat, is not only the world’s smallest bat, but also arguably the smallest mammal in the known world.

Our world is home to over 1,200 species of bats, but the smallest of them all can only be found in a few caves in Thailand and Myanmar. The aptly-named Bumblebee Bat is so tiny that it can rest comfortably on an average-size human finger. Its size ranges from 29 to 33 mm, and it only weighs 2 grams. The wingspan of the Bumblebee bat is 170 mm.

Discovered in 1973, by Thai biologist, Kitti Thonglongya, who also gave the species its official name, the Bumblebee Bat has since become a popular tourist attraction in both Western Thailand – with roosts identified in 44 limestone caves – and Myanmar, where it is known to inhabit 5 caves.

Rutin chicken, a domestic hybrid dubbed ‘the world’s smallest chicken’ has become incredibly popular in China lately, fueling a veritable pet craze.

Technically, the rutin in chicken is not a chicken. It is a cross between a quail and a partridge, but people have dubbed it the “world’s smallest chicken” and the nickname stuck. To be fair, it fits too, as the birds are about the size of an average human fist and weigh only about 50 grams. They are super cute as well, and their size makes them suitable for relatively small enclosures that come with lights, plants, stairs, and even dollhouse-like sleeping quarters.

Measuring around 10 cm, with a diameter comparable to that of a cooked spaghetti, the Barbados Threadsnake (Tetracheilostoma carlae) is by far the smallest snake in the world.

Spotting a Barbados threadsnake for the first time, you could swear it was an earthworm. They are actually comparable in size and diameter, with the largest specimen ever found measuring only 10.4 centimeters, and are also blind. They also typically weigh under one gram and are small enough to coil on an American quarter. The species was officially discovered slithering beneath a rock near a patch of Barbadian forest in 2008 by evolutionary biologist S. Blair Hedges, but little has been discovered about its ecology and behavior since.

Geospiza difficilis septentrionalis, aka the Vampire Finch, is a small bird with a very unusual diet – other bird’s blood.

Found on only two small islands in the Galapagos Archipelago – Darwin and Wolf – the vampire finch is a subspecies of the sharp-beaked ground finch, a relatively small and harmless-looking bird. However, as the specie’s name suggests, it has a very sharp beak, which it sometimes uses to break through more than just fruits and nuts. The vampire finch got its name from its bizarre habit of pecking at larger birds’ skin and feeding on their blood whenever other food sources are scarce.

Macracantha arcuata, aka the horned orb-weaver spider or the wishbone spider, have a pair of intimidating long horns growing out of their abdomen.

Although both male and female Macracantha arcuate spiders feature spines on their abdomens, it’s the females that stand out. They have three pairs of spines coming out of their abdomens, but it’s the middle one that immediately catches your attention, as the spectacular horns that project upward and then curve toward each other are roughly three times longer than the spider itself. The other two pairs of spines are short and relatively inconspicuous in comparison. If you’re afraid of spiders in general, a female Macracantha arcuata is a terrifying sight to behold, but you should know that the species is actually harmless to humans.

Using their large feet and fast stride, the Western and Clark’s grebes can run as far as 20 meters on water, making them the only bird and the heaviest animal on Earth capable of doing so.

If you exclude Jesus Christ, whose biblical feat of walking on water is literally considered a miracle of the New Testament, only a handful of creatures are known to be able to walk or run on water. Most of them are small insects, but there is also a small basilisk nicknamed the Jesus Christ lizard for very obvious reasons, but the largest of them all are two bird species – the Western and Clark’s grebes. They can run on water for up to 7 seconds and distances of about 20 minutes as part of an impressive mating ritual.

Cymothoa exigua, popularly known as the tongue-eating louse, is a parasitic isopod that attaches itself to the tongue of its fish host, severs circulation, causing the organ to necrose and fall off, and then becomes the new tongue.

We’ve covered a bunch of terrifying parasites on Oddity Central, but few can hold a candle to the tongue-eating louse in terms of creepiness. This critter is one of the few that actually does the phrase “what nightmares are made of” justice. It enters fish through the gills, attaching to them until it matures, at which point it changes sex from male to female. Once this process is complete, the parasite starts to make its way to the fish’s mouth, where it attaches itself to its tongue using its incredibly powerful legs. It then pierces the host’s tongue with its strong bite and begins to suck the blood out of it. The blood vessels can’t keep up with their appetite, and the tongue eventually withers and detaches from the fish.

The hooded pitohui, a small bird endemic to Papua New Guinea, is the first and only scientifically-confirmed poisonous bird in the world.

The Melanesian people of Papua New Guinea have long known to keep their hands off of hooded pitohui, but to the western world, the bird’s toxic potential was only discovered by chance just over three decades ago. In 1990, ornithologist Jack Dumbacher was on the Pacific island looking for birds of paradise. He had set up delicate mist nets between the trees to catch them and ended up with some hooded pitohui birds in them as well. As he tried to grab the birds out of the traps, they scratched and bit his fingers, and he instinctively put his hands in his mouth to soothe the pain. Almost immediately, Dumbacher felt his lips and tongue go numb. They then started to burn and did so for hours. Later, suspecting that the symptoms were caused by the bird, he took a pitohui feather and put it in his mouth. The numbness and ensuing pain quickly returned. He had unknowingly discovered the world’s first poisonous bird.

The Ladoum sheep, known as the “king of sheep” in Senegal, is considered a mark of prestige and a status symbol in the African country, with prices for top specimens exceeding $85,000.

A hybrid of the Mauritanian ‘Touabire’ breed and the Malian ‘Bali-bali’, the Ladoum was first bred outside Senegal’s capital of Dakar in the early 1970s. For such a young breed, the Ladoum is incredibly popular in the West-African nation, with well-off families and breeders spending small fortunes on a specimen, and those who can’t afford one dreaming of one day having enough money to buy it. To understand just how revered the Ladoum is, in a country where about 40 percent of the population lives on $1.90 per day, some people spend tens of thousands of dollars on a single sheep.
