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.

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.

Of the roughly 1,300 known species of bat, very few can be described as cute and cuddly, but the tiny Honduran White Bat is definitely one of these rare exceptions.

Also called the Caribbean White Tent-Making Bat, this adorable flying mammal can be found in the tropical forests of Central-American countries like Honduras, Nicaragua, Costa Rica and western parts of Panama. It has a distinctive white fur, which is characteristic of only five other known bat species, and is very small for its genus, with the largest recorded individual being under 5 centimetres in length. Because of its white color and generally cute look, as well as the fact that it doesn’t live in caves and doesn’t suck blood, the Honduran White Bat is considered a living, breathing contradiction of bat stereotypes.

The town of Ingham, in Northern Queesnland, has reached “crisis point” after hundreds of thousands of fruit bats invaded the place last month. Things have gotten so bad that kids are afraid to go to school anymore, and rescue helicopters can’t land at the local hospital.

Flying foxes, also known as fruit bats currently outnumber humans in Ingham by hundreds of thousands. And they’re not the only bat species that decided to make the Australian town their home over the last month. According to local sources, people here have been invaded by four different species of bats, each of which mates at different times, making it really hard for authorities to intervene. To make matters worse, the bats are protected by law, so locals can’t take matters into their own hands either.

Dozens of families in and around the city of Cairns, in Australia, have been forced to temporarily abandon their homes after flying foxes started dropping dead on their properties due to the unbearable heat.

Cairns residents started reporting massive numbers of spectacled flying foxes dropping out of trees on Monday, when temperatures in Australia’s Queensland region rose to above 40 degrees Celsius. According to animal experts, the nocturnal mammals cannot sustain an internal temperature of over 40 degrees, and with no way to cool off, their organs start to shut down and they eventually die. Wildlife rescuers have been working around the clock, using using spray bottles and drippers too cool off and hydrate the helpless creatures, but there’s only so much they can do. The flying fox colonies in the Cairns area have already sustained heavy losses and the number of fatalities is expected to rise for as long as the heatwave continues. But apart from the environmental issues, the massive number of dead bats rotting away so close to people’s houses has now become a become a serious public health issue as well.

It’s hard to imagine a fragile spider killing and eating a full-grown bat. I mean there’s no way a tiny spider could have any sort of muscle power over a fully grown bat, right? Believe or not, there are eight-legged bugs out there that can pounce on bats and eventually devour them. And when they can’t, they rely on their superior web-spinning skills to get the job done.

One of the earliest sightings of bat-eating spiders occurred way back in 1941, when Indian scientist G.C. Bhattacharya (of the Bose Research Institute) walked into a cowshed in a village near the city of Calcutta. In a letter to an unknown publication, he wrote a detailed account of his experience: “Entering into the cowshed, I noticed a pipistrelle bat struggling to drag itself out of a crevice between two bamboo strips of a wall and a big house-spider was seen firmly gripping the former by the neck with its powerful mandibles.” No matter how much the little bat kicked, and screamed and flailed, the spider held on with a death-grip. “There was intermittent gasping and screaming of the bat,” Bhattacharya wrote.

Eventually, he focused a torch on the spot and as soon as the light fell on the pair, the bat screamed loudly and managed to drag itself through a certain distance on the matted shed wall. About 20 minutes later, the bat, thoroughly exhausted, stretched out its wing and gave in.   Bhattacharya then captured both victim and predator in a glass jar and took them home for closer observation. The next morning, he found the spider resting peacefully at the top of the jar, while the bat lay dead at the bottom, untouched. It had visible injuries to its neck and had died sometime during the night.
