The Joanina Library of the University of Coimbra Alta and Sofia is one of two Portuguese libraries to house colonies of bats as natural deterrents for bugs that would otherwise feed on old books and manuscripts.

As unusual as having a colony of Common pipistrelle bats living behind the bookshelves of one of the most beautiful libraries in the world, the curators of this historical marvel swear that the flying rodents provide an indispensable service – they feast on bugs that would otherwise damage or feed on old books. And with some of these ancient manuscripts being virtually priceless, it’s no wonder that the bats are regarded as helpful guardians.

Named after the Argentinian family who developed the breed in the middle of the 19th Century, Falabella is widely regarded as the world’s smallest horse breed, with an average height of just 70cm.

The origins of the Falabella breed are shouted in the mists of legend. Some say that their bloodline can be traced back to the Andalusian and Iberian breeds that the Spanish conquistadores brought with them to South America. When the Spanish were driven off, the horses were left to fend for themselves in a harsh, resource-poor environment. As a result, by the mid-19th century, smaller, inbred animals were being observed in the herds of Mapuche, in southern Buenos Aires province. It was these specimens that were specifically bred to create even smaller animals, which eventually led to the creation of the modern Falabella breed we know today.

The western hook-nosed snake, a small snake endemic to the deserts of the United States and Mexico, is famous for the shape of its snout and for farting to confuse its enemies.

Cobras and rattlesnakes have their deadly venom, constrictors like pythons and Boa have their strong musculature, but the western hook-nosed snake doesn’t have either, so it relies on a more unusual defense mechanism – farting. When threatened, it emits rumbling air bubbles from the cloaca – the common opening for excretion at a snake’s rear end. Known and cloacal popping or defensive flatulence, this strange means of defense is designed to confuse predators long enough for the snakes to escape.

Ring-necked parakeets are native to the foothills of the Himalayas and temperate regions of North Africa, but for the past century and a half, they’ve also made a home for themselves in London.

No one knows exactly when and how London became a home for feral parakeets. In fact, there are so many urban myths tied to these green exotic birds that it’s hard to settle on just one explanation. Many of the theories going around on the streets of London as well as on the internet involve legendary artists like Jimi Hendrix or Audrey Hepburn, but no one can truly say how the birds came to the English capital. One thing is for sure, though – London’s parakeets are here to stay, they are thriving, and they are expanding, with recent estimates placing their number in the tens of thousands.

The workers of several ant species have large, flattened, and slightly concave heads that they use as plugs to block entrance to their colonies’ nests.

The so-called ‘door head ants’ are soldier ants with armored heads that match both the size and the shape of the entrance to their colonies’ nests almost to perfection. They function as living doors, using their heads to plug shut the nest and only allow access to other members of the colony while keeping unwanted guests out. Door head ants can be found in several ant genera, including Cephalotes and Carebara. How these species developed the exact size and shape as the entries to their nests is the result of millions of years of evolution.

Luo Yingjiu, an 81-year-old man in China’s Hubei Province, has spent the last three decades of his life taking care of sick and disabled animals at the “world’s loneliest zoo”.

It was during the 1980s that Luo Yingjiu started buying animals and taking them home with him.

Yakei, a 9-year-old female Japanese macaque at the Takasakiyama natural zoological garden, shocked staff by fighting her way through several strong males to become the first female alpha in the troupe’s 70-year history.

The story of Yakei’s rise to power sounds like the plot of a Hollywood epic. Born into the 677-strong troupe B at the Takasakiyama zoo in Japan’s Oita city, the female inherited the rank just under her mother, as per the rules of macaque society. The higher an individual’s rank, the greater its access to food, mates and resting locations. Last March, Yakei fought her own mother and won, becoming the leader of the other females in her group. For most females, this would have been more than enough, but for Yakei it was only the first step to a much more ambitious goal – leader of the entire troupe.

The Onagadori (‘honorable fowl’ in Japanese) is a rare chicken breed known for its exceptionally long tail, which can reach over 10 meters, putting even peacocks to shame.

Of the seventeen chicken breeds considered Japanese national treasures, the Onagadori is the only one to have “special” status. Ever since it received this status in 1952, exports of Onagadori birds and eggs were forbidden, so there are very few specimens, if any, found outside of Japan today. The breed is famous for the non-molting, and thus incredibly long tails of roosters, which, if kept in the best conditions with high levels of animal husbandry, can grow for the lifetime of the bird.

The Japanese Bobtail is a rare car breed whose distinctive feature is the presence of a short, bunny-like tail, instead of the long, flexible tail of most other felines.

No one knows exactly when this unusual cat breed arrived in Japan, but it has been a part of Japanese culture for at least several hundred years, being frequently featured in traditional art and folklore. In the early 1600s, the breed played a major role in preserving Japan’s silkworm production, by taking on rodents, and by the next century, the bobtail was already the dominant cat breed being kept in Japan. No one knows whether it was because of its distinctive tail, which looked like it had been bent and broken, its friendly personality, or its talkative nature, but the Japanese Bobtail became extremely popular in the Japanese country and remains so today. However, it remains extremely rare outside the borders of Japan.

Because of their slender physique, incredibly long legs and upright pose, Modern Game Bantams are considered by many the fashion models of the poultry world, but few know that they also have a mean streak.

Modern Game chickens take their name from the ‘old English game’, a chicken breed brought to the English Isles in the 1st century by the Romans. Bred exclusively for cock fighting, the old English game grew immensely popular over the century because, well, raising a chicken was relatively affordable, and cockfighting was a “sport” anyone could partake in. However, things changed in 1849, when cock fighting was officially banned in England, by order of the Queen. All of a sudden, the old English game was retired, and a new, modern variant took its place.
