ant mimicry
Saturday, February 9, 2013
Interestingly enough, there are hundreds of species of spiders - most of is profits - jumping spiders - which is very similar to ants. Yes, it's a spider in the picture above.
Some arachnids use this disguise to hunt for insects that are not afraid of ants, or to protect themselves from predators predatory spiders. Others, of course, the ants may prey on itself, like a wolf in sheep's clothing. (This can not be done spiderman)
King of Camouflage
Some species can make a silk-like webs, and prey-prey time can be saved by dressing like a mummy for a long time, the color of the net-like color they create another camouflage for spiders .. It is useful to confuse predators such as dragonflies fly, robber flies or small birds that may try to dive for the delicious spider prey from the nest.

Chameleon Tongue 5 Times Faster than Jet Aircraft
Thursday, February 23, 2012
God created something great with the perfect design. Design organs in animals has been designed in such a way according to the food. So is the chameleon. However, of these animals are found astonishing facts. The fact is the speed super chameleon tongue catch its prey. Jurriaan de Groot of the University of Leiden, and Johan van Leeuwen of Wageningen University, taking X-ray films of high-speed, ie 500 frames per second, in order to investigate how the chameleon's tongue works when capturing prey. These films show that the chameleon's tongue tip acceleration of 50 g (g = gravitational constant). The acceleration is five times greater than can be achieved by a fighter jet.

Zologi textbooks explain that ballistic chameleon tongue is reinforced by a piece of the accelerator muscle (accelerator). This muscle extends when pressing down on the bones of the tongue, in the form of stiff cartilage in the middle of the tongue, the wrapping. However, in a study that has been approved for publication by the journal Proceedings of the Royal Society of London (Series B), two experts who studied the morphology of the eating habits of chameleons found other elements associated with the rapid movement of the animal's tongue.
The researchers This dissected tissue of the tongue and found that the accelerator muscle was not strong enough to generate the force necessary for this alone. By examining the chameleon tongue, they discovered the existence of at least 10 packs of slippery, hitherto unknown, between the tongue accelerator muscle and bone. These sheaths, which is attached to the tongue bone at the end closest to the mouth, the fibers were observed to contain spirally wound protein.
fibers are compacted and deformed when the accelerator muscle contracts and store energy like a piece of rubber band is depressed. When it reaches the tip of the tongue round bone, tight sheaths and simultaneously sliding it extends and contracts with the power and throw the tongue. As quickly as the fibers slide from the bone of the tongue, the sheaths separate from one another like the tubes of a telescope, and the tongue reaches maximum stretch. Van Leeuwen said, "This is a telescopic catapult."
slingshot has another characteristic that is very striking. The tip of the tongue takes the form of hollow when struck prey. When ejected, the tongue may protrude as far as six times the length at rest in the mouth, and two times his own length.
muscle groups with different properties of the tongue impeccably cast, memercepatnya, causing the tongue to take shape when it hit the prey and suck then quickly pulled. Muscle groups is by no means mutually inhibit each function, but works in a synced the hit prey and pull the tongue back into the mouth in less than a second. Moreover, thanks to cooperation between the visual system and brain, the position of prey were measured and the command for ballistic tongue to "shoot!" Given by the nerves that transmit signals in the brain.

Cockroach's brains is Healthy for Humans
Wednesday, February 22, 2012
Cockroaches are usually seen as a dangerous animal health, can be found in damp places and dirty hotel. But scientists believe that they could hold the secret to treat the most formidable insects. According to the Daily Mail, testing has found a network of brain and nervous system of insects can kill more than 90 percent of MRSA infections and E-coli without harming human cells.
Simon Lee, a postgraduate researcher from the University of Nottingham said that the cockroach has strong antibiotic properties after discovering nine different molecules in cockroach tissues that are toxic to bacteria. He said: "We hope that the molecule may eventually be developed into drugs for E-coli and MRSA infections are increasingly vulnerable to current drugs. "These new antibiotics could potentially provide an alternative to currently available medications, current medications may be effective but have serious side effects and unwanted." He added: "Insects often live in an environment that is unhealthy and unhygienic where they face various kinds of bacteria. It is therefore logical ways memngembangkan insect defenses to protect themselves against micro-organisms. " Mr Lee's research focuses on the study of specific properties of antibacterial molecules that are currently being tested in these super bugs. According to the Society for General Microbiology, industrial pharmacy is producing fewer and fewer new antibiotics due to lack of financial incentives, so that high demand for alternative sources of new drugs.
Tomorrow, Mr Lee will present his findings before the public meeting of friends of scientists in the fall at the University of Nottingham. Dr Naveed Khan oversees the work Lee. He said: "superbugs like MRSA Insects have developed resistance to standard therapies and treatments that we do. "They have demonstrated the ability to infections that can not be cured, and has become a major threat in our fight against bacterial diseases. So, there is a constant need to find additional sources of new antimicrobial to deal with this threat. "

Found, Fossil Life 200 Million Years of Age
Sunday, August 21, 2011
This eel has many advantages possessed primitive eel.
Biologists reported a new species of eel found in underwater caves as deep as 35 meters on the edge of an island nation of Palau, western Pacific. Experts call it a living fossil that is similar to the eels first swim of about 200 million years ago. As quoted from the Daily Telegraph, August 20, 2011, the findings were published in the journal Proceedings of the Royal Society B. Penemuan itself took place in March last year by a team led by Masaki Miya of the Institute of Museum of Natural History in Chiba, Japan. species of eel found tangible brown small fish with different anatomical characteristics of modern eel. Instead, it has many advantages of primitive eels that live in the early Mesozoic era, when dinosaurs roamed the earth. The parallels include a disproportionate head size, body compressed into a short, collar like openings in the gills, tail and fin rays at the ends of bones jaw called the premaxilla.This finding is itself quite remarkable and even eels are put into a separate species, namely Protoanguilla Palau. When first encountered, using hand nets and lights, researchers collected eight samples of eels that have a length of about 6-9 centimeters long is. After that, DNA tests conducted to assess the genetic history of the eel. According to research, to date, Palau is the only place the discovery of the species. Nevertheless, researchers estimate, the distribution of eels is still quite broad. For information, Charles Darwin called a living fossil with a term to describe the species still survived until now though has been handed down over millions of years

So Many Reasons Why The Bronze Goes To… Pandas!
Saturday, June 4, 2011
In the complex world of animals that amuse us, the pecking order is often murky. Dogs and Cats interchange with ease between the top two spots but what about third place? Monkeys, hamsters, hippos; all quite amusing to be sure. But here’s my case for the mighty Panda for the bronze. Even they were the inspiration for the cartoon “Kung Fu Panda”. These creatures are so adorable and I’d be happy to have a panda!
