Mr. Peebles from Pekin, Illinois, USA was claimed as the world's smallest cat. Mr. Peebles is two years old cat weighing just three pounds and measuring 6.1 inches in height. This anomaly is caused by a genetic disorder.
In the forests of Costa Rica, a tiny insect has been found. Tinkerbella nana is a fairyfly that is only 250 micrometers long. It is one of the smallest arthropods ever discovered.
How could they even find such a tiny creature? The researchers admit that it was not easy given the biodiversity of the forest. “It is possibly equivalent to finding a solitary needle in 200 haystacks,” Dr John Noyes notes.
These beautiful birds are called purple-crowned fairy wrens, endemic to northern Australia. The picture was taken by ornithologists (bird banders) studying the birds as part of population monitoring in Australia. The way they are holding them is called "photographer's grip" which gently secures the legs while keeping the rest of the bird free. Handling time is generally very short.
The Principality of Sealand is a tiny, self-proclaimed nation that started on an old sea fort in the North Sea. A former British Army major declared it independent in 1967, and it's known for its quirky history. Even though it hasn't become a recognized country globally, Sealand has its own currency, passports, and devoted fans. In fact, for £99.99 you can become a knight of Sealand! It's a unique story of a small place dreaming big and capturing people's imaginations.
Whenever anyone mentions the word possum, I immediately recall the Simpsons episode where Homer conducts the monorail.
However, unlike the possums found in Homer's closet, the animal you see right above is a western pygmy possum, native to Australia. It might look absolutely tiny, but it's actually one of the largest species of pygmy possum in the world. Another interesting fact is that like all pygmy possums, the western pygmy possum is great at entering mini hibernating periods called torpor.
While this may look like sushi, it's actually Argentina's pink fairy armadillo. This rarely seen animal has silky white hair and a pinkish carapace; it ranges in size from 3.3 to 4.6 inches (84 to 117 millimeters) long, making it one of the smallest species of armadillos. The animal is also nocturnal and has the ability to bury itself in lightning speed given its long claws, which are an astonishing one-sixth the length of the body. ...
This blackpoll warbler (Setophaga striata), weighing no more than 12 grams can migrate over the Atlantic Ocean from New England and eastern Canada to the Caribbean islands - a 2500 kilometer flight - nonstop! These finding were discovered after researchers tagged these little birds with miniature geolocators on their backs. They concluded that no other "bird this size migrates for this long in one go... it is truly one of the most amazing migratory feats ever recorded." ...
The long-lasting search and debate around the size and identity of the world's smallest free-living insect seems to have now ended with the precise measurement and second record of the featherwing beetle species (Scydosella musawasensis). Described in 1999, representatives of this minute beetle have recently been retrieved once again from fungus in Colombia. The smallest individual measured the astounding 0.325 mm. ...
Angustopila dominikae is the only known specimen measuring the astounding 0.86 mm in shell height. That means ten of them could fit into the eye of a large sewing needle at the same time! Until now, the smallest known land snail was a thai species measuring about 0.9 millimeters long. Researchers believe that it probably feeds on microorganisms and may be hermaphroditic. However, because the team didn’t recover any DNA, a lot of uncertainly remains.
Proteins are subatomic biomolecules. They're produced by cells, so it's logical to assume that they are much tinier than cells, and of course, much tinier than the organelles that produce them. In a remarkable achievement, scientists have now obtained the first-ever photographs of single proteins. Using a "holography electron microscope," researchers tested on a range of protein samples, all just a few nanometers in size. Hemoglobin, the protein that transports oxygen in red blood cells, and cytochrome c, the protein that transfers electrons within the body, were just two examples.
These tiny water bears, called Tardigrades (meaning "slow stepper"), are water-dwelling, eight-legged, segmented micro-animals. They have been sighted from mountaintops to the deep sea, from tropical rain forests to the Antarctic.
Tardigrades are notable for being perhaps the most durable of known organisms; they are able to survive extreme conditions that would be rapidly fatal to nearly all other known life forms. They can withstand temperature ranges from 1 K (−458 °F; −272 °C) to about 420 K (300 °F; 150 °C), pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without foo ...
