Den Camera Shows Baby Bears’ Birth

Thanks to fiber-optic camera technology, you can watch real-time footage of a black bear named Lugnut as she hibernates in a den beneath an upturned sugar maple in northern Maine. 

Just two weeks ago, the 8-year-old Lugnut gave birth to two cubs (watch video above.) Because of their demands, her hibernation won’t be as deep as usual, and she’ll wake regularly to check on them. Most of the time, however, the cubs will be curled up against Lugnut’s warm belly, nursing as she sleeps.

The cubs will likely stay in the den for several months, and with their mother for more than a year, departing only when they’ve learned enough to survive on their own. The camera is expected to stay on indefinitely, so viewers will have a chance to watch them grow up.

Bio-luminescent Spewing Shrimp

A shrimp named Acanthephyra purpurea spews a bioluminescent cloud from its mouth when attacked. The burst of bright substance is enough to put would-be predators off their mark.

The bright blue bioluminescent cloud the shrimp expels isn’t "vomit." Instead, luminous fluid probably originates in the hepatopancreas – an organ that plays roles similar to the liver and pancreas in us – and, depending on the species of shrimp, can come from the mouth or nearby organs.

Watch a Baby Condor Hatch and Grow on Live Webcam

You can watch a pair of California condors, among the most endangered birds in the world, as they raise a new baby in view of a webcam set up by scientists at the San Diego Zoo’s Safari Park.

Shatash, 21, and her partner Sisquoc, 28, will take turns caring for the 9-ounce egg until it hatches in early March.

The hatching process will take a day or two, and if the chick runs into trouble along the way, Sisquoc and Shatash will be standing by to help.

Right now, Shatash and Sisquoc are tending to a life-like faux egg while theirs sits in an incubator. Closer to the end of the 52-day incubation period, scientists will switch the artificial egg for the real one.

California condors are very nurturing parents. They’re also very egalitarian: Both parents take care of their young. Sisquoc and Shatash will discipline, groom and play with their baby. They’ll give it feathers to play with and rub their baby’s soft pink face with their own.

 Five to six months after Shatash’s egg hatches, her chick will start to hop and flap around the nest as it learns to fly. By then, its wispy white feathers will have turned to grey. The fledgling will stay with its parents for about a year imitating them and learning how to pick up food and forage. During this time, the young bird will also learn how to interact with other condors.

Today there are only about 400 California condors left in the world.

High-Speed Animal Flight Videos Show Hidden Aerial World

A Dutch program called Flight Artists sent high-speed video tools to amateur photographers around the world.

The challenge was to capture nature in flight. Over the course of a year, the contest drew 460 amateurs who uploaded more than 2,400 slow-motion video clips shot with their complimentary cameras. A jury of scientists, philosophers and video experts then picked their favorites, which can be seen below.

For more information, including descriptions of all these videos, see the original article here.

World's tiniest vertebrate is a frog

The world's smallest vertebrate - animals that have a backbone - is a frog that could sit within the confines of your fingernail, a new study reports.

Scientists found the new species, which on average is just 7.7 millimeters long, in the southwestern Pacific island nation of Papua New Guinea.

The frog, scientifically named Paedophryne amauensis, spends its life in moist leaf litter on the floors of tropical wet-forests. Males call out with a continuous series of high-pitched notes at dawn and dusk, resembling the sound of crickets.

Typically, small frogs dry out quickly, but this tiniest species has a habitat that stays moist for most of the year. 

Researchers say the animals have simplified skeletons and are born directly as frogs, as opposed to first going through a tadpole stage. Researchers believe these creatures eat even smaller animals, such as mites.

Previously the smallest vertebrate was believed to have been a fish known as Paedocypris progenetica, which matures at 7.9 millimeters. There has been speculation that aquatic habitats are home to the world's smallest and largest vertebrates, but this frog contradicts that theory.

The World's Heaviest Insect

 A nature-lover has revealed how he spent two days tracking down a giant insect on a remote New Zealand island – and got it to eat a carrot out of his hand. The former park ranger discovered the giant weta up a tree and his real life Bug's Bunny has now been declared the largest ever found.

The find is the world's biggest insect in terms of weight, which at 71g (2.5 ounces) is heavier than a sparrow and three times that of a mouse.

There are over 70 types of Weta species in New Zealand but the giant weta has been named the biggest insect in the world because of its weight. A female giant weta filled with eggs can reach up to 70g or more and the largest of the species are found on Little Barrier Island. They are usually less social and more passive than other weta.

Their diet consists of plants, other small insects and fruit. Their size is an example of island gigantism, which is a biological phenomenon leading to a larger size than their mainland relatives because of their isolation and lack of large predators.

Hula Painted Frog Bounces Back From Extinction

A species of frog that was thought to have been made extinct during the drainage of the Hula marshlands in Israel, has appeared again after more than 50 years of hiding.

 The Palestinian or Hula painted frog (Discoglossus nigriventer) originally went missing when the Jewish National Fund drained the marshlands around the Hula Valley in the 1950s. The swamp was a breeding ground for malaria, and the disease was killing off the population. The JNF removed the water from the swamp and redirected the flow of water to the river Jordan with artificial estuaries.

The operation led to huge destruction of ecosystems, wiping out water plants, tropical aquatic ferns, the ray-finned fish Acanthobrama hulensis and the cichlid fish Tristramella intermedia. Until this week, it was thought that the hula painted frog was among the lost species. But a routine patrol at the Ha’Hula lake by Israel’s Nature and Parks Authority turned up a mysterious, unknown female frog and took it back to the lab for testing.

It was soon confirmed that it was a Hula painted frog, and the rare species had hung on amongst the devastation of its habitat.

High-Speed Video Shows How Hummingbirds Stay Dry

How does a hummingbird keep dry? A series of high-speed videos reveal that hummingbirds shake themselves like dogs. Of course, dogs don’t shake while balanced delicately in mid-air, flapping their wings 45 times per second. At a glance, that might not seem like a pressing problem. But for a bird that weighs a few grams and lives on a razor-thin margin of bioenergetic error, it’s a life-or-death matter. See more in the original article here.

Murmuration of Thousands of Starlings

The video above was taken at the River Shannon in Ireland. It shows thousands of starlings in shape-shifting flocks that are referred to as a "murmation."

Flesh-Eating Piranhas Bark When Angered

Hollywood has given the piranha a rough reputation as a vicious fish with a penchant for biting. But according to scientists, the piranha barks more than it bites.

 The team of biologists plunged a hydrophone (an underwater microphone) into a tank of captive red-bellied piranhas and listened in to the different sounds they make in different situations.

 So far, the team registered three distinct noises. When piranhas enter into a confrontation they’ll make a barking noise. When they’re fighting for food or circling an opponent, a piranha will make short percussive drum-like sounds. And when their jaws snap at each other, a softer croaking sound is produced.
