The largest library in the world

The largest library in the world is the U.S. Library of Congress in Washington, D.C
The British Library the world's other great library houses a collection comprising of 150 million items as against the 130 million housed by the Library of Congress.

However in terms of shelf space the Library of Congress shelves occupy a space of about 850 km (530 miles) while the British Library shelf space is 625 km (388 miles) long. The Library of Congress' collection of books is in the range of 29 million while the number of books of the British Library is about 25 million.


The Library of Congress was established in April 1800 and is spread over three buildings namely The Thomas Jefferson Building, The John Adams Building and The James Madison Memorial Building; the collection of the library consists of along with books, newspapers from across the world, microfilm reels (500,000), comic books (6000), manuscripts (58 million), films, maps (4.8 million) and sound recordings (2.7 million); the rarest item in the library is a Gutenberg Bible dating from the 15th century.









Animals

Dodo: the archetype of extinct species (extinct since late 17th century)


 The Dodo (Raphus cucullatus) was a flightless bird that lived on the island of Mauritius. Related to pigeons and doves, it stood about a meter tall (three feet), lived on fruit and nested on the ground. The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history, and was directly attributable to human activity. The adjective phrase “as dead as a dodo” means undoubtedly and unquestionably dead. The verb phrase “to go the way of the dodo” means to become extinct or obsolete, to fall out of common usage or practice, or to become a thing of the past.


Cave Lion: one of the largest lions ever (extinct 2,000 years ago)

 The cave lion, also known as the European or Eurasian cave lion, is an extinct subspecies of lion known from fossils and a wide variety of prehistoric art. This subspecies was one of the largest lions. An adult male, which was found in 1985 near Siegsdorf (Germany), had a shoulder height of around 1.2 m and a length of 2.1 m without a tail, which is about the same size as a very big modern lion. This male was even exceeded by other specimens of this subspecies. Therefore this cat may have been around 5-10% bigger than modern lions. It apparently went extinct about 10,000 years ago, during the Würm glaciation, though there are some indications it may have existed as recently as 2,000 years ago, in the Balkans.


Great Auk: largest of all auks (extinct since 1844)

 The Great Auk was the only species in the genus Pinguinus, flightless giant auks from the Atlantic, to survive until recent times, but is extinct today. It was also known as garefowl, or penguin.
Standing about 75 centimetres or 30-34 inches high and weighing around 5 kg, the flightless Great Auk was the largest of the auks. It had white and glossy black feathers. In the past, the Great Auk was found in great numbers on islands off eastern Canada, Greenland, Iceland, Norway, Ireland and Great Britain, but it was eventually hunted to extinction. Remains found in Floridan middens suggest that at least occasionally, birds ventured that far south in winter as recently as in the 14th century.

Caspian Tiger: the third largest (extinct since 1970)

 Caspian Tiger: the third largest (extinct since 1970)
The Caspian tiger or Persian tiger was the westernmost subspecies of tiger, found in Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan and Uzbekistan until it apparently became extinct in the 1970s. Of all the tigers known to the world, the Caspian tiger was the third largest.
The body of this subspecies was quite stocky and elongated with strong legs, big wide paws and unusually large claws. The ears were short and small, and gave the appearance of being without hair on the tips. Around the cheeks the Caspian tiger was generously furred and the rest of its fur was long and thick. The colouration resembled that of the Bengal tiger. Male Caspian tigers were very large and weighed 169-240 kg. Females were not as large, weighing 85-135 kg. There are still occasional claims of the Caspian tiger being sighted.

Aurochs: a very large type of cattle (extinct since 1627)

 One of Europe’s most famous extinct animals, the aurochs or urus (Bos primigenius) were a very large type of cattle. Aurochs evolved in India some two million years ago, migrated into the Middle East and further into Asia, and reached Europe about 250,000 years ago.
By the 13th century A.D., the aurochs’ range was restricted to Poland, Lithuania, Moldavia, Transylvania and East Prussia. The right to hunt large animals on any land was restricted to nobles and gradually to the royal household. As the population of aurochs declined, hunting ceased but the royal court still required gamekeepers to provide open fields for the aurochs to graze in. The gamekeepers were exempted from local taxes in exchange for their service and a decree made poaching an aurochs punishable by death. In 1564, the gamekeepers knew of only 38 animals, according to the royal survey. The last recorded live aurochs, a female, died in 1627 in the Jaktorów Forest, Poland. The skull was later taken by the Swedish Army and is now the property of Livrustkammaren in Stockholm.
In the 1920s two German zookeepers, the brothers Heinz and Lutz Heck, attempted to breed the aurochs back into existence (see breeding back) from the domestic cattle that were their descendants. Their plan was based on the conception that a species is not extinct as long as all its genes are still present in a living population. The result is the breed called Heck Cattle, ‘Recreated Aurochs’, or ‘Heck Aurochs’, which bears an incomplete resemblance to what is known about the physiology of the wild aurochs

Irish Deer: the largest deer that ever lived (extinct about 7,700 years ago)

Irish Deer: the largest deer that ever lived (extinct about 7,700 years ago)
The Irish Elk or Giant Deer, was the largest deer that ever lived. It lived in Eurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene and early Holocene. The latest known remains of the species have been carbon dated to about 5,700 BC, or about 7,700 years ago. The Giant Deer is famous for its formidable size (about 2.1 meters or 7 feet tall at the shoulders), and in particular for having the largest antlers of any known cervid (a maximum of 3.65 meters/12 feet from tip to tip and weighing up to 90 pounds).
Discussion of the cause of their extinction has still focused on the antlers (rather than on their overall body size), which may be due more to their impact on the observer than any actual property. Some have suggested hunting by man was a contributing factor in the demise of the Irish Elk as it was with many prehistoric megafauna, even assuming that the large antler size restricted the movement of males through forested regions or that it was by some other means a “maladaptation”. But evidence for overhunting is equivocal, and as a continental species, it would have co-evolved with humans throughout its existence and presumably have adapted to their presence.

Biggest Fish

Biggest Fish



The world’s biggest fish is the rare plankton-feeding whale shark (Rhincodon typus), which is found in the warmer parts of the Atlantic, Pacific, and Indian Oceans. The largest specimen on record, captured in 1949, was 41 ft. 6 in. long, measured 23 ft. around the thickest part of the body, and weighed an estimated 14.8-20.7 tons.

Strongest Bite


 Experiments carried out with a Snodgrass gnathodynamometer (shark-bite meter) at the Lerner Marine Laboratory in Bimini, Bahamas revealed that a 2m 6ft 6 ¾ in long dusky shark (Carcharhinus obscurus) could exert a force of 60 kg/132 lb between its jaws. This is equivalent to a pressuure of 3 tonnes/cm² or 19.6 tons/in² at the tips of the teeth.

Longest Goldfish



The world’s longest goldfish (Carassius auratus) is owned by Joris Gijsbers and measured 47.4 cm (18.7 in) from snout to tail-fin end on March 24, 2003 in Hapert, The Netherlands.

Noisiest Animal in sea


The low – frequency pulses made by BLUE WHALES when communicating with each other have been measured up to 188 decibels, making it the loudest sound emitted by any living source. They have been detected 850 km/ 530 miles away.

The world's most intelligent fish

The world's most intelligent fish

Introducing the world's most intelligent fish - he can play football, basketball and even limbo dance under a bar.

Comet the goldfish has been trained by his owner to perform the astonishing range of aquatic activities on demand.

And that's not all - watery genius can also play fetch with a hoop, slalom around a series of poles and push a rugby ball over a set of posts.
 Swam dunk: Comet prepares to shoot a hoop

Catch of the day: Comet's owner used a training technique called positive reinforcement to teach the fish tricks


Owner Dr Dean Pomerleau, 41, used a training technique called positive reinforcement to train two year old common goldfish Comet to carry out the tricks.

But there's nothing fishy about his claim - in fact, he says anyone can do the same with their own pet.

Fish training expert Dr Pomerleau said: "There is mounting evidence that fish are more intelligent than people give them credit for.

"With the correct tools and the basic promise of a food reward, fish can very quickly learn complex tricks - like the limbo, slalom or playing fetch.
Nice try: Comet has been trained to push a miniature rugby ball over a set of posts

 Gold ring: Comet's owner adapted training methods previously used on dolphins

Now people in the market for a dog might want to consider a fish instead." Positive reinforcement is a training technique where the fish is rewarded with food when he successfully completes a task.

Dr Pomerleau added: "We've used techniques that we've customised for pet fish, but are based on those used to train dolphins and other marine mammals.

"The basic idea is to reinforce successive, increasingly accurate approximations of a desired behaviour.

"In training an animal to press a lever, for example, simply turning toward the lever will be rewarded at first.

"Then, only turning and stepping toward it will be rewarded.

"With a little time and repetition, the animal will learn to perform the complete behaviour to receive the reward."
 Pipe dream: Dr Pomerleau has teamed up with pet product firm R2 to design a special kit to help people train their fish

Dr Pomerleau already holds the official world record for having the fish with the largest repertoire of tricks, with a three year-old calico fantail named Albert Einstein.

But four inch long Comet has already learnt Albert's array of tricks and is set to take the crown of the world's most intelligent goldfish.

Hooked: Using food as a reward, Comet quickly learned complex tricks


Dr Pomerleau, from Los Angeles, California, has teamed up with pet product firm R2 Solutions to design a special kit to help people train their fish.

The kit features an array of training tools including goal posts, slalom poles and tunnels for your pet to swim through, as well as an instructional DVD.

R2 Solution president Russ Ronat said: "When people see the tricks, after the initial disbelief, they want to learn how its done and teach their own fish too.

"Not only is this product fun, but it also has great educational value."

World records set by men

World records set by men, the oldest as well as incredible records on the smallest have been unveiled worldwide and amazed a lot of people with awesome facts. Today we will discover the records on the world’s biggest in terms of size.
The biggest hand

Lin Hua from Jiangsu, aged 24, was recognized by theGuinness World Records for the biggest hand in 2007. When he was born, his left thumb, index and middle finger are larger than others. Growing up, large hand seriously affected his daily routine and work. In July 2007, he was hospitalized in Shanghai. At that time, his left thumb was 26 cm long, his index finger was 30 cm and his middle finger was 15 cm. In total, the weight of his hand was up to 10 kg. Seven-hour operation helped to reduce the size of Liu's fingers and thumb.
The biggest arthropod

A spider crab from Japan is claimed to be the world’s biggest arthropod. The legs of a full-grown spider crab can measure up to 3.6 m. However, researchers have not capture a full-grown one yet because they live at great depths.

 World's Largest Goldfish

It might look like an enormously generous fairground prize. But no goldfish bowl in the world could contain this catch. The orange koi carp weighs 30lb – the same as an average three-year-old girl – and is thought to be one of the largest of its kind ever captured



Atlantic Sea Ravens: What’s a bright fish like you doing in a dive like this?

Atlantic Sea Ravens: What’s a bright fish like you doing in a dive like this?



Like the daffodils and forsythia that brighten up our New England springtime, the North Atlantic sea raven is a garish splash of color in the cold, green waters of the Gulf of Maine – though more unexpected than spring flowers. As David Abel, the Boston Globe reporter lucky enough to go on a recent dive with Brian, describes the surprising sight: “Appearing to be taking a nap on one rock is a bright-yellow sea raven, a monstrous-looking fish about a foot long, with prickly fins, globular eyes, several rows of sharp teeth, and a fleshy mouth ringed with spiny tabs that resemble a poorly groomed beard.”

The sea raven is a member of the sculpin tribe, and, as such, is characterized by a wide mouth, slender body, and large pectoral fins. Sea ravens are not always yellow; their colors range from non-descript browns, to blood red, to the sunburst of color you see in this picture. Robert Glenn, the Chief Marine Fisheries Biologist with the Massachusetts Division of Marine Fisheries, speculates that a sea raven may change colors depending on whether it’s hunting or breeding. According to Glenn, it’s possible that the bright colors emerge in the fall and spring, and are associated with breeding behaviors. But, he says, so little research has been done on this fish that nobody really knows.

While the fish in this picture might look Jimmy Buffet tropical, it has antifreeze in its veins. The sea raven can live at the bottom of Gulf of Maine in temperatures that sometimes approach the freezing point of salt water. Many kinds of sea life make antifreeze, and researchers are looking at the potential commercial application of these compounds, such as better preserving frozen foods, treating hypothermia victims, and making freeze-tolerant crop plants. The chemical composition of the sea ravens’ de-icer is different from every other fish in the sea, and has sparked a great deal of scientific curiosity.

Survival strategies are essential at these icy depths. Formidable rows of teeth and a non-picky appetite allow the sea raven to feed on just about anything it can find, from worms to shellfish to smaller finfish. It doesn’t have to expend a lot of energy hunting, though. The sea raven has a powerful ability to blend in with its background, using coloration and frilly appendages to look like just another algae covered rock. It’s a sit-and-wait predator, and uses its fantastic camouflage to hide in the background until something really big and tasty comes along. Glenn reports that he has found whole Jonah crabs and 16-inch wolffish in sea raven stomachs. This is especially remarkable when you consider that sea ravens only grow to about a foot and a half long, themselves. I would love to be a shrimp on the wall at that dinner party.

Sea ravens are not commercially important (the reason so little research has been done about them), but they are a common bycatch species. Unfortunately, because of their large mouths their stomachs tend to fill with water when they are caught and brought to the surface. Even if they are released alive they cannot deflate rapidly, so they float on the surface where they are vulnerable to predation by seabirds.

Where can you find these fascinating fish? Sea ravens prefer rocky or hard-bottom conditions, like those found in Cashes Ledge, an underwater mountain range 80 miles east of Cape Ann. This special placeis one of the biological treasure chests of the Gulf of Maine that CLF is working hard to protect.

Brian has plans to dive on Cashes Ledge several times over the next few years, and we are very excited to show you what other unexpected gems he finds. Stay tuned!

Amazing Facts You Didn’t Know About Animals!!!

 Amazing Facts You Didn’t Know About Animals!!!

It’s mind-blowing to think about the multitude of animals that exist in this world. From the tiny flea to the great blue whale, each animal possesses a unique quality that makes it stand out from the rest. Even if you’re a zoology expert, you might be surprised by some of these 25 amazing facts about animals. Prepare to be astounded by the resilience, physical abilities, and sheer brilliance of these magnificent creatures.

Housefly

Houseflies don’t allow their short lifespans (14 days) to hinder their musical abilities. They always hum in the key of F.


Bat


 Bats are the only mammals that can fly, but wouldn’t it be awesome if humans could fly too?


Beaver

 Because beavers’ teeth never stop growing, they must constantly gnaw on objects to keep them at a manageable length. Their teeth would eventually grow into their brain if they didn’t maintain them.


Butterfly

 Butterflies have two compound eyes consisting of thousands of lenses, yet they can only see the colors red, green and yellow.


Dog

 Dogs’ nose prints are as unique as human fingerprints and can be used to identify them.



Elephant

Elephants can smell water up to 3 miles away. They are also one of the three mammals that undergo menopause – the other two being humpback whales and human females.


Cat

A cat has 32 muscles in each ear. All the better for them to eavesdrop on your conversations and plot your demise.


Flea

Fleas can jump up to 200 times their height. This is equivalent to a man jumping the Empire State Building in New York.


Giraffe

Giraffes have no vocal cords and their tongues are blue-black in color.

Hummingbird

Hummingbirds are the only birds that can fly backwards and their wings can beat at up to 80 times per second.


Humpback Whale

 Humpback whales create the loudest sound of any living creature. And you thought the loudest sound came from that two-year-old you sat next to on your trans-continental flight, didn’t you?



Kangaroo

Kangaroos use their tails for balance, so if you lift a kangaroo’s tail off the ground, it can’t hop.


Koala

Koala bears almost exclusively eat only eucalyptus leaves and nothing else.


Ostrich

 Ostriches can run faster than horses, and the male ostriches can roar like lions.


Oyster

 Oysters can change gender depending on which is best for mating. Talk about successful adaptation.


Poodle

Contrary to popular belief, French poodles actually originated in Germany. Maybe you should’ve named her Gretl instead of Fifi.


Seahorse

 The slowest fish is the seahorse, which moves along at about 0.01 mph.



Snail

 Don’t try this at home, but a snail can grow back a new eye if it loses one.



Spider

On average, there are 50,000 spiders per acre in green areas. Bet you’ll think twice before going outside now – unless you’re this guy.


Squirrel

 You might want to thank a squirrel the next time you enjoy the shade of a tree. Millions of trees are accidentally planted by squirrels that bury nuts and then forget where they hid them.


Crocodile

Here’s a tidbit that might be useful if you plan on becoming the next Steve Irwin: To escape the grip of a crocodile’s jaw, push your thumb into its eyeball – It will let you go instantly.


Ant

 Beware an ant uprising! There are one million ants for every human in the world. These resilient creatures also never sleep and do not have lungs.



Tiger

Tigers not only have stripes on their fur, they also have them on their skin. No two tigers ever have the same stripes.


Turtle

You can tell a turtle’s gender by the noise it makes. Males grunt and females hiss.
