A diver recently captured footage of what he claims is a 20-foot (6-meter) long great white shark dubbed Deep Blue. Off the western coast of Mexico's Baja California, Guadalupe Island (map) is a shark mecca, drawing people from around the world hoping to catch a glimpse of one of these majestic creatures. Biologist Mauricio Hoyos Padilla posted a Facebook video of what he claims is the biggest great white shark ever filmed: An approximately 20-foot (6-meter) long female dubbed Deep Blue. According to the California Department of Fish and Game, great white sharks can grow up to 21 feet (6 meters) long. However, most great whites are around 12 to 14 feet (3.6 to 4 meters) long, says Christopher Lowe, a shark biologist at California State University in Long Beach.
As waterproof video cameras become more popular, people are increasingly filming these massive beastsa€”and expanding scientists' views on the upper limit for white shark size. At the same time, numbers of white sharksa€”the largest predatory fisha€”have dropped precipitously in recent decades due to overfishing for their fins and teeth and getting caught in fishing nets. The overall drop in population means that many white sharks don't get old enough to reach huge sizes, like Deep Blue. Hoyos Padilla, director of Pelagios Kakunjá, a nonprofit supporting migratory marine species of the Mexican Pacific, estimates Deep Blue is roughly 50 years old.
That's because Hoya Padillaa€”as well as Lowea€”believe that Deep Blue's video, as well as more knowledge of sharks, can help dispel some of their myths. For one, the majority of white sharks won't immediately swim up and attack you, says Lowe: The video captures Deep Blue nonchalantly gliding next to the diver on top of the cage.
There's also debate about the merits of public cage diving, which is depicted in the new video, he explains. Though it does increase awareness of sharks, there's a risk that the fish either rely on the bait from the divers as a food source, or that they start associatinga€”and seeking outa€”people with food. Tim Samaras has a storm in his headlights and the world's fastest high-resolution camera in the trailer behind.
Guided by the laptop weather map reflected in his window, Tim Samaras rushes to catch up to a dying thunderstorm.

A ground fire ignited by a lightning storm near Elephant Butte, New Mexico, paints the horizon with brown smoke. WASHINGTON (July 24, 2014)—National Geographic Fellow and celebrity chef Barton Seaver and acclaimed nutrition scientist P. FOODS FOR HEALTH is a compendium that brings together key elements of what we grow and eat in an easy-to-use fashion. The book is arranged alphabetically within six food categories — vegetables, fruits, proteins, whole grains, fats and oils, and beverages — while the appendix provides a handy guide to herbs and spices. Combining old favorites with new grocery items — broccoli and bok choy, brown rice and barley, pears and pomegranate, peas and pinto beans, FOODS FOR HEALTH explores food and its place in history and cultures from around the world. The folate in fennel aids in brain function and limits the risk of heart disease and stroke.
Beans can essentially fertilize their own soil; their root systems harbor bacteria that convert atmospheric nitrogen to a form the plant can use. Canola oil has the lowest saturated fat content of any oil commonly available in the United States and it contains omega-3 and omega-6 fatty acids in healthy proportions. Black tea can reduce the risk of stroke and its antibacterial qualities guard against cavities and gum disease. Don’t store carrots near apples, pears and potatoes, which emit ethylene gas that can give carrots a bitter taste.
Kiwifruit contains more Vitamin C than oranges as well as high amounts of potassium and Vitamin E, all considered important for healthy blood vessels.
Featuring invaluable tips, recommendations for food pairings and sample menus, this book is an always-there reference, a useable cooking guide, a handy health manual and an inviting, browsable read. Acclaimed chef, author, speaker and National Geographic Fellow Barton Seaver is a leading voice in the sustainable food movement and has been recognized by the Seafood Choices Alliance and Blue Oceans Institute for fostering a responsible and sustainable seafood choice ethic.

The grasslands of Russia and Kazakhstan are host to an animal that has roamed the earth since the Ice Age, but may soon become extinct: the saiga, a hump-nosed antelope whose population has declined by more than 95 percent since the early 1990s.
The critically endangered saiga, which stands just about two feet tall, is in urgent need of protection from poachers who illegally kill the animal for its horns and sometimes, its meat. Today, an estimated 150,000 of the animals remain in the wild, due in large part to conservation efforts made to restore the population.

Unless initiatives are taken to revive the dwindling saiga population, most people will never come in contact with the unique-looking antelope, which is most often recognized by its bulging proboscis that scientists suspect may be used to warm the cold winter air or filter out dust.
But poachers are after the antelope for its horns, which are used in Chinese medicine, and have hunted the animal extensively throughout the nineteenth and twentieth centuries. While poachers have been the main cause of the mammal’s endangerment, the saiga has also faced a number of other hardships. Additionally, keeping the animals in zoos is challenging: past attempts have proven largely unsuccessful, since saigas are difficult to keep alive in captivity. The greatest hope for the saiga population are the conservation efforts made by governments and conservation organizations that emphasize tighter law enforcement and legislation against poaching, research into the saiga species’ survival, satellite tracking of remaining animals, community awareness, and the establishment of protective areas. Fauna & Flora International works closely with the Kazakh government and the Association for the Conservation of Biodiversity of Kazakhstan to conduct research about the animal, strengthen state agencies that aid in the species’ survival and spread awareness to rural communities. The saiga antelope has an unusual-looking face with a long nose, which is believed to warm up air in the frigid Central Asian steppe. It will be technology and communication that speeds the impetus to conserve species and biodiversity as a whole.

Society Field Inspection 2016: Gulf of CaliforniaDescribed by Jacques Cousteau as the "aquarium of the world," the Gulf of California in Mexico is threatened by coastal development, climate change, and other human activities. Support National GeographicWe've supported more than 11,000 grants to scientists and others in the field.Learn more about our work. Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi. With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa.
In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave. BANABA ISLAND, Kiribati—Asbestos dust covers the floors of Banaba’s crumbling colonial houses, buildings, and schools. Welcome to our inaugural column of Ask Your Weird Animal Questions, where we give you a chance to satiate your curiosity about the wild world. The males, who are much smaller than the females, sniff out a mate and give her the love bite of a lifetime, hanging on until an enzyme fuses his body into hers. Nilantha Aajeewa of Kalawana, Sri Lanka, wrote in last fall asking for help identifying a reptile after reading about zoologist Ruchira Somaweera and his study of the horned lizards of Sri Lanka.
A lot of species are also determined with sophisticated DNA techniques, like this new species of humpback dolphin that was hiding in plain sight in Australia. Last, as the stunning number of annual new-species discoveries attests, some animals are just plain good at not being seen. While many land animals regenerate body parts, such as deer and their antlers, it does seem that many regenerating animals are aquatic, like sea stars, tunicates, and salamanders. For instance, some aquatic species simply regenerate easily and often like sea stars, while other species may take longer or have more trouble—so we may think of the super-regenerators more often. Guedelhoefer added that aquatic creatures tend to pop up more “simply because more biologists chose to spend their days collecting on the beach rather than digging in the mud,” he says. Progress has been made with creating tooth material that genetically matches human teeth needed for implant. We hear of occasional stories of dolphins saving a swimmer, but we don’t seem to hear about any who take a hapless victim further out to sea.
For the anglerfish, if the male ends up morphed into the female, when does the actual “intercourse” begin? We’re Moving!As of October 22, 2014, Weird & Wild will be hosted on National Geographic's main news site. Tim Samaras and his crew chased the slow-moving storm cell until they ran out of road, and now can only watch as it moves on.
He hopes to be the first to photograph the split-second event that triggers a lightning strike. The storm was moving southeast at some 40 miles an hour—too fast to provide an opportunity for the Kahuna. Each section includes historical and agricultural food facts as well as science-based nutritional information, health benefits and environmental considerations. Seaver and Newby highlight health benefits, offers preparation tips and advise consumers on what to look for and what to avoid when perusing the supermarket aisles or farmer’s market and deciding what to make for dinner or pack in a school lunch box.

Annually, the group publishes more than 125 new books for adults, families and kids and releases 250+ new DVDs and digital downloads of the Society’s films and TV shows, and these National Geographic titles are available in more than 35 local-language editions. In the early 1990s, millions of these antelopes freely roamed the grasslands of Kazakhstan, Mongolia, Russia and Uzbekistan.
But an increase in the saiga’s numbers has also come with an increase in poaching, causing the animal’s safety to remain a continuous problem.

With saigas becoming more abundant again, hunting has become more easy and thus lucrative, [since] less fuel has to be spent in search of the animals and more males can be killed at one go,” said Maria Karlstetter, Saiga Programme Manager at Fauna & Flora International, in an e-mailed statement. To protect endangered species of rhinoceros from being hunted, some conservationist groups in the early 1990s even encouraged hunters to go after the saiga instead. The antelope has been nearly wiped out by hunting for its horns, which are in high demand for use in traditional Chinese medicine.
Mass die-offs have killed thousands of the animals for reasons still largely unclear to scientists. In several instances in which the mammals were kept captive at zoos, they fatally injured themselves while trying to escape. And Karlstetter hopes that enough people will care about the hump-nosed species’ survival to aid in the protection effort meant to restore its population.
Humans are becoming more and more heartless as we get further advanced in technology and communication.

How do they avoid the usual consequences of inbreeding—i.e., the mom fish using the sperm of her male offspring? He will gradually melt into her until there’s nothing left but sperm, which she will be able to use as needed to fertilize her eggs. We consulted with Somaweera, who thinks Aaejeewa may have seen a reptilian rainbow known as the hump-nosed lizard, Lyriocephalus scutatus. Actually the animal had been seen before by locals and indigenous hunters who helped researchers identify it.
If it was a perpetual pleasure down to the last cell, it wouldn’t be so bad for the poor male fish. The Kahuna is too massive to quickly reposition, so he needs to find a place where lightning is striking consistently in the same spot. By sunset another storm had erupted 50 miles to the south, and the crew was on the road until 1 a.m.

While special photographic and film collections, travel books, nature shows, birding guides and atlases are a core focus of the Society’s products, books and videos dealing with subjects as diverse as animals, the human mind, history, world cultures and the cosmos are also produced.
And now, the steppes of Russia and Kazakhstan are empty, devoid of the antelopes that once roamed the land in herds of thousands. They toured the desert islands off the southeastern coast of the Baja Peninsula and they listened to presentations by more than a dozen experts, including several whose Baja California research is funded by the Society.

Often animals may be known to many but not yet scientifically recorded by scientists as a separate species. Moments later, a prey bird (hawk?) swooped down, picked up the bird in its talons, and flew off. Far easier to navigate are the tight grids of farm roads crisscrossing the Texas and Oklahoma Panhandles.
Here he is aiming his Phantoms—extremely high-speed cameras that are still only a hundredth the speed of the Kahuna. Through the book’s pages, readers are sure to gain an increased appreciation that, from farm to fork, what they eat matters, not only for their health and longevity but for that of the Earth. It had a wonderful titanium blue colour body and its legs and tail were dark blackish blue. Some scientists have suspected pasteurellosis, a bacterial infection, to be behind the mysterious deaths. This culinary tour shines the spotlight on 148 foods that have huge nutritional value and the least environmental impact. Others suspected poisoning or contamination of pasture grass – even though there is no concrete evidence supporting that theory. But while the mass die-offs significantly affected the already-dwindling saiga population, the biggest threat to the endangered species remains poachers hoping to cash in on the animals’ horns.
