Three-Foot "Shrimp" have additional Than 30,000 Lenses per Eye?

A shrimplike super predator of the very old seas may have had additional than 30,000 lenses in each eye, granting the animal improved vision that would have rival or exceed that of living insects and crustaceans, a new learn says.

The finding is base on a pair of 515-million-year-old stalked eyes belong to the meter-long (three-foot-long) Anomalocaris, whose Latin name translate roughly to "weird crustacean."

The ancient eyes—each about 0.8 to 1.2 inches (2 to 3 centimeters) long—were found in shale deposits on Australia's Kangaroo Island.


Unlike umans—whose eyes each have a solitary, large lens—insects and crustaceans have eyes with multiple, usually hexagonal lenses, each of which transfer separate bits of information to the brain.
When study co-author Diego C. García-Bellido and colleagues began counting Anomalocaris's fossilized lenses beneath a microscope, they could scarcely believe their eye.We're chatting 16,000 lenses on half an eye," said García-Bellido, a paleontologist at the Spanish Research Council in Madrid."Wow—that was the most mind-blowing feature of it all."

The other side of the pair of Anomalocaris eyes is entrenched in rock and can't be studied, García-Bellido said, but it's possible both sides had equal amounts of lenses.

"Great White Shark" of Its Time?

The main animal of the Cambrian period (542 to 501 million years ago), Anomalocaris had a round, plated mouth with teeth-like serrations and spiny arms for grasping prey such as trilobites, a type of extinct arthropod.
At the Kangaroo Island site, scientists also found Anomalocaris coprolites—or fossilized poop—in the shale deposits. (Read more about fossil feces.)It's quite incredible—you find bits of pieces of trilobites in it," said García-Bellido, whose team has received funding for future work from the National Geographic Society's Committee for Research and Exploration. (The Society owns National Geographic News.)

The new study offers more proof that the creature was the super predator of its era—"probably the great white shark of the Cambrian ocean," García-Bellido said.Anomalocaris and its relations were so successful, in fact, that they lasted for another 40 million years until probable being outcompeted by fish.

Unlicensed Dog get Bus for a turn

Likely driving without a license or even a learner permit, Richard McCormack's dog, Woodley, manage to dislodge the handbrake of McCormack's double-decker bus and drive downward a major road in Darwin, Australia yesterday. McCormack believe that Woodley, a 2-year-old German Koolie, erudite how to drive by observing him driving the means of transportation over the last two years. Woodley allegedly took the vehicle for a spin while McCormack was in a store.



"I came out and saying the bus going down the road. I couldn't believe it," McCormack told The Sun. it seems that this isn't the first time Woodley has attempted to go all Thelma & Louise, McCormack explained. "He sits next to me when I'm driving and in the driver's seat when I'm not. The brake pedal is on the dashboard and he's seen me let go it many times. He was just copying me. He's tried it before," said McCormack.

According to NTN News, Bystander Phil Newton could not believe his eyes when he saw Woodley driving the 20-ton, double-decker bus from side to side Darwin's industrial zone (...as Woodley usually drives a compact hybrid.)

The vehicle was finally brought to a stop when Newton jumped in an open window and put the handbrake rear on after considering that a dog was navigating the mobile home. "This was weird, even for the Northern country," Newton told NTN News.

Bears leave hairless at Zoo expert bewildered

A spectacled bear name Dolores (pictured) is fairs an unconventional look after losing approximately all her hair.

Since 2007 the female spectacled bear and two of her female kin at Germany's Zoo Leipzig have been going hairless—mysterious experts. Zoo experts are operational to cure the bears' non-life-threatening condition, zoo curator



Spectacled bears—also called Andean bears—live in the mountains of South America and are the continent's only bear species. Armando Castellano, leader of the Andean Bear Conservation Project in Ecuador, said that he'd seen a similar case about a decade ago in a rescue spectacled bear.

"We were very scared, because it was the primary time we had seen this," Castellano said.

Keepers in Ecuador place that bear, which had before been fed human food—counting Coca-Cola—on its usual diet of fruits and bamboo, and added enhancement items, such as toys and exotic foods, into the bear's enclosure. Four months later the fur grew back.

Alike cases have occur in a Bolivian zoo and in Peru, Ximena Velez-Liendo, a spectacled bear specialist, said by email. It’s unidentified whether a be short of of nutrition is the culprit in the Leipzig bears' situation. awaiting a cure is found, keepers have been applying medical ointment to the bears' skin, which becomes itchy without its defensive fur.

Innovative "Albino" Spider establish in Australia


The new found trapdoor spider isn't a factual albino, since it motionless has some pigment—its body is brown, similar to those of other trapdoor spiders.But the 1.2-inch-wide (3-centimeter-wide) arachnid has been dubbed the albino trapdoor spider until it does officially describe as a new species.

People in a small town in Western Australia establish the strange-looking spider close to his house, captured it in a jar, and sent it to the museum.

"Unluckily we know nothing about its life history. We assume that they live in burrows for their whole lives—like all trapdoor spiders—and when males mature, they stroll in search of females in their burrows," .

Trapdoor spiders get their name since they use soil, vegetation, and silk to build doors to their burrows that are hinged with silk. The arachnids then pop out when they sense the feelings of passing prey, which include insects, other arthropods, and small invertebrates. The spiders also mate inside the burrows, where "males of all species almost certainly have to lift the female body up to access her genital opening, which is located on the underside of the abdomen,".

The newfound spider is careful rare, Harvey added—it's currently the only known specimen of its kind."Spiders are a varied group of animals that fascinate and terrify many people," though they're crucial in keeping insect populations in check."The world would be a poorer place without spiders."

Bizarre Life Found In deep Ocean


Scientists plumb the lowest point of the Mariana Trench -- the sincere part of the ocean on the planet -- have recognized gigantic amoebas lurk miles and miles beneath the waters.

The creatures are called xenophyophores, and scientists from the Scripps Institute of Oceanography at UC San Diego spotted them in the cold, crushing depths 6.6 miles under the white caps.

"They are charming giants that are extremely adapted to extreme circumstances but at the same time are very fragile and poorly studied”.




Scripps scientists said xenophyophores are in the middle of the main person cells in existence, often growing longer than four inches. Recent studies indicate that by trapping particles from the water, xenophyophores can concentrate high levels of lead, uranium and mercury and are thus likely highly resistant to large doses of heavy metals. They also are well suited to a life of darkness, low temperature and high pressure in the deep sea."The identification of these gigantic cells in one of the deepest marine environments on the planet opens up a whole new habitat for further study of biodiversity ... and extreme environment adaptation,"

To reach the bottom of the ocean requires special equipment. Levin worked with Eric Berkenpas and Graham Wilhelm -- Remote Imaging engineers from the National Geographic Society -- to build and launch "drop cams."

"Drop cams are versatile autonomous underwater cameras containing an HD camera and lighting inside of a glass bubble," Berkenpas explained. By wrapping high-resolution cameras in a thick-walled glass sphere, scientists were able to drop cameras capable of withstanding the extreme pressure of all that ocean. At a depth of 6.6 miles, the water above can cause more than eight tons per square inch of pressure.

Life is surprisingly abundant at these extreme depths, despite the cold and pressure. According to Dhugal Lindsay of the Japan Agency for Marine-Earth Science and Technology, the Dropcam movie also depicts the deepest jellyfish observed to date.

Galápagos Tortoise in addition to infant





A Galápagos tortoise dwarfs her baby in this photo released in October by the Taronga Western Plains Zoo in New South Wales, Australia.

The hatchling weighs roughly 3 ounces (87 grams) at birth. It will take 30 ears for the baby to reach a similar girth as its mother—a huge 564 pounds (256 kilograms).

Galápagos tortoises are the longest-lived of all vertebrates, with regular lifespans of more than a hundred years.

Hooded Seal Facts

The Hooded Seal (Cystophora cristata) is an arctic seal also recognized as Crested Seal. Belong to the family Phocidae, it can only be found within North Atlantic central and western regions from Svalbard to the Gulf of St. Lawrence, all through the northern areas of Atlantic Ocean, in part near Labrador, and in northeastern Newfoundland down to New England. It lives on ice packs and in the Atlantic Ocean's deep waters.

The Hooded seal is known for and named as such due to the 'hood' of the male, a sole and strange addition that can be inflated to what resembles a red balloon. This appendage hangs from the forehead to the mouth's front and bulges out when the male is either threatened or excited. It is most characteristic, though, when it is mating. Its head is black, and its fur is silvery or grayish with a prototype of dark clouded spots. The front flippers have large claws and darker color than the body. The male is usually 2.6 meters in length and about 400 kilograms in weight while the female is smaller at 2.03 meters and about 300 kilograms on the average.

The hooded seal's most visible and most peculiar behavior still pertains to the male's 'bulge'. It balloons to about twice the size of a football when the male blows it up by closing one of its nostrils. The trunk becomes bigger especially when the male is mating. The hood forms at first in young males that are about 4 years. It become fully developed by the time he reaches 12 years. The bulge size varies according to individual body size although the standard size is around 6.3 liters.




The hooded seal lives alone usually but converges in big groups during mating and reproductive season. This seal species has the shortest period for lactation in the middle of all mammals at four existence only. Feeding mainly on deepwater fish like redfish, herring, Greenland turbot, cod, capelin, flounder, halibut, squid, octopus, shrimp, and mussels, a hooded seal can live as long as 30 to 35 years.

Snail Surfer


A feminine violet snail, Janthina exigua, hangs from a float of home-based mucus.

Scientists have extended observed snails "surfing" the load on such rafts, which can dish up as flotation devices, egg-storage areas, and platform for youthful snails.

But it was unknown how the family of fewer than ten bubble-rafting species evolved their odd lifestyles, said Celia Churchill, a Ph.D. student at the University of Michigan in Ann Arbor.



Churchill had already supposed that bubble rafters evolve from bottom-dwelling snails that create mucus-filled egg masses. To pinpoint the rafting snails' neighboring relatives, the team sequenced DNA from bubble-rafting class and other possible "sister families," using molecular technique to piece jointly an ancestral family tree.

The results exposed that bubble rafters descend from a bottom-dwelling snail call the wentletrap, which still exists today.

Both snail groups exude mucus from their feet-muscular organs at the basis of their bodies. But in its place of making egg masses, the bubble rafters use the quick-hardening mucus to make rafts with the "consistency of bubble wrap,", whose new study appeared recently in the journal Current Biology.

frill-necked lizard,

Frill-necked Lizard
Kingdom: Animalia
Phylum: Chordata
Class: Sauropsida
Order: Squamata
Family: Agamidae
Genus: Chlamydosaurus
Species: Chlamydosaurus kingii
Common Name: Frill-necked lizard,frilled dragon,bicycle lizard



The frill-necked lizard, which belongs to the agamid family, can be mostly established in northern Australia and southern New Guinea. Its name derives from the large frill surrounding its neck. The frill necked lizard stays folded for most of the time, though whenever this strange animal is in danger it opens up its mouth and the frill folds out. By responsibility this lizard seem better and scarier to its potential predators. If this fail, the lizard has one more defense mechanism to empoy , its speed. The frilled dragon is very fast and can even "sprint" on its two hind legs. in fact the way it runs is very funny and is the cause this lizard is also called "bicycle lizard" .



The frill-necked lizard is one of the largest lizards in existence. The males can reach up to almost a metre in total length, with females being significantly smaller in size.

Frill-necked lizards are characteristically insectivorous, and their diet consists of cicadas, beetles, temites, butterflies and moths. They also eat spiders, other lizards and some times small mammalls.

Piranhas frightening Brazil




Authorities in a state in Brazil's northeast are scrambling to get the fright and the sink your teeth into off the beach after piranhas sunk their teeth into about 100 beachgoers, UOL Noticias report.

The trouble quite frightening given piranhas' horror-movie teeth and aptitude to sink them into human flesh -- has been the main at the main beach area in Piaui state; authorities said they need to act fast to reduce a piranha overpopulation circumstances.




Last weekend, at least 100 bathers were treated at the hospital in Jose de Freitas not far from Terezina, Piaui's capital, after being bitten on the heels or toes at the local beach.

"Since they have no predators, piranhas have in progress attacking people on the beach," said Romildo Mafra, a local environment official.Ecological official so far have additional tilapia to the piranhas' local food chain hoping to quell some of the predators' hunger.

Orange Crocodile Stylish Season


Orange is the innovative green in crocodile method this period.

Snappy, an 8-foot-2-inch crocodile is generous haute-couture orange skin and he's look fabulous and sentiment fine!

But it's not actually a fashion statement. It's a result of aggressive the water filter of his enclosure at Roaming Reptiles animal park in Australia.



"Snappy's attractive territorial and he attack the filter one day, and a few weeks after that, notice he was orange."
"It doesn't appear to have exaggerated him at all. He's still got a healthy hunger, is normally aggro and doing everything he always does," 

A crocodile specialist interviewed by the Herald Sun said he believe the croc is in ideal health despite his outrageous new look."Our guess is that it is something in the water such as iron or tannins from leaves or some red algae, that oxidises when it dries,”. Snappy is expected to go back to his normal color eventually.It seems absolutely fabulous new colors are all the rage in the animal kingdom. Discovery News recently reported on glow-in-the-dark cats.

18-foot green anaconda Found


A huge 18-foot green anaconda (Eunectes murinus) was captured by a group exploring the Rewa River in Surinam. Where are Ice Cube, J-Lo, and Owen Wilson when you need them?

Niall McCann, a 29-year-old biologist from Wales, Robert Pickles, and their guides found the anaconda while trekking through a section of the Rewa River never before surveyed by scientists. They captured the snake in 2009, but didn't release photos until lately."The animals there had never seen people before so you could get incredibly close to them,”.The squad dotted the large serpent on the river bank, but didn't undertake it at primary.

"When you primary see amazing of that size you just don't know how it will react. Three weeks later, the anaconda was still in the similar spot. The explorers had gained knowledge catching caiman and smaller anacondas since their first come across with the giant, and felt sure they were up to the 18-foot long challenge.


"We exhausted about 20 minutes preparing the landscape so we could give confidence it to move inland, we didn't want it to go into the river as it could have runaway," ."It would make bigger out then coil, ready to strike, then make bigger out and coil again. I said, 'right, next time it stretches I'm going to go for it.' It started to stretch out and I just leapt on top of it with both hands behind its head, my knee on its back and the other chaps piled on behind me," 

"It was a struggle for the first 30 seconds or so as it tried to move its head from side to side. It tried to scratch at us then Ash, the head guide, came round the front and grabbed it by the jaws as I lifted it up -- wrapping its jaws with tape so it could no longer bite us

The snake wranglers made sure the anaconda couldn't escape with its mouth taped, which would have been a death sentence for an animal with no appendages. The team then measured it and released it.

At 18 feet, the anaconda might be one of the best ever measured.

A 17 foot 1 inch (521 cm ) long female that weighed 215 lb (97.5 kilograms), was recognized by Jesus Antonio Rivas in The Life History of the Green Anaconda (Eunectes murinus), with Emphasis on its Reproductive Biology. Other information of anacondas reaching 24-27 feet have been report by reliable sources. Though rumor exist of anacondas attainment lengths of more than 30 feet, herpetologists doubt the accuracy of these claims.
