Shark v. Predator

Sharks: Rulers of the aquatic world. Moulded by evolution into a fierce predator, few dare to challenge this king of the ocean. But the truth is there are over 400 species of sharks… and most of them are not equipped to fight off hungry, aggressive predators. Even ones much smaller in size. But what kinds of animals would be daring enough to take on these killing machine? Seals, crocodiles, octopi, bobcats and even birds, to name a few, have been seen going head to head with these elite killers. And we’ve uncovered the footage to prove it. Home video and photographs captured by tourists and fisherman reveal the rare moments when a shark ends up on the receiving end. It’s time for nature’s ultimate underwater showdown: Shark vs. Predator!

Follow See Why This Colourful King Of Birds Is The Centre Of Conservation Efforts The western tragopan (or jujurana, which means “king of birds”) is one of the most vulnerable pheasants in the world; just 3,300 survive in the wild today. This species can be found only in the western Himalaya and is most protected in the state of Himachal Pradesh, India. National Geographic grantee Munmun Dhalaria created a short film that features her sighting of the bird, one of the longest jujurana sightings ever to be documented in the wild. Dhalaria’s film also highlights the bird’s courtship display in captivity and the state’s overall conservation effort to protect the king of birds.

Follow What's The World's Most Littered Plastic Item? Cigarette Butts Cigarette filters are made of a plastic called cellulose acetate. When tossed into the environment, they dump not only plastic, but also the nicotine, heavy metals, and many other chemicals they’ve absorbed into waterways, and eventually oceans. But, there are solutions that can help our health and our planet.

Follow Sparse Snowpack Worsens California Drought Crisis "It could be pretty grim," says California's chief of snow surveys, looking toward the summer months. During one of the worst droughts in centuries, state officials are concerned. The snowy stockpile of water in the Sierra Mountains is the state's real reservoir, supplying about a third of the water used by farms and cities when it melts each spring and early summer. National Geographic followed California’s top snow surveyor on a recent snow inspection, and he's sounding the alarm.

Follow See How This School Of Tiny Fish Uses Bacteria To Glow In The Dark August 14, 2019 — While scuba diving at night along a coral reef in the Solomon Islands, marine biologist and National Geographic Explorer David Gruber witnessed what he describes as "the closest [he's] had to an Avatar moment." Thousands of flashlight fish swam before him, forming shapes, and illuminating the dark ocean waters. What he saw could be the largest school of glowing fish ever seen and captured on camera. Casting a vibrant blue glow as they swim, flashlight fish owe their bioluminescence to the bacteria that grow in an organ underneath their eyes. It's a symbiotic relationship that allows the bacteria to obtain extra oxygen needed to survive, and the fish benefit from the glowing light emitted from the organ, which they can "blink" on and off using special skin folds. In a recent study published in PLOS ONE, it was observed that flashlight fish use the glowing light to coordinate their schooling and avoid predators.

Follow Behind The Scenes: A Rumour About Opiates And Pangolin Scales Is Debunked Scientists at the National Fish and Wildlife Forensics Laboratory in Ashland, Oregon recently investigated a claim about pangolin scales—that they contain tramadol, an opiate used for pain relief that, like all opiates, has the potential for abuse. Concerned by the rumors and inquiries by law enforcement, the forensic team decided to do a chemical analysis to look for the presence of tramadol in several samples of pangolin scales. The results showed there was no presence of the chemicals. Pangolins are believed to be the most trafficked mammals in the world, and across Asia and Africa their populations are dwindling. The demand for their scales stems from the belief that they have medicinal benefits.

Follow TIL: Some Sharks Can Glow In The Dark You probably know that your visual perception of the world is a bit different than your pets’. Dogs see things with less colour than humans, snakes can see infrared, and if you have a pitbull, it lives in a world where red and green are the same colour. This brings up a good question. Why do you have a pitbull? You should get a cat instead, and when you do, it is important to know that your new friend can’t focus on objects farther than 6 metres away. The point is, animals have evolved to see in a variety of ways. But how can we see things through their eyes? Marine biologist and National Geographic Emerging Explorer David Gruber collaborated with a research team to develop lights and camera filters that allowed him to do just that, underwater. Through their work, the team discovered biofluorescence in an abundance of aquatic species. This “glowing” trait has to do with how an organism absorbs and emits light. Research has indicated that this radiance is possibly used for communication and camouflage. One caveat: You need a certain species of eyes (or David’s camera) to see it. Swell sharks (Cephaloscyllium ventriosum) have fluorescent proteins inside their skin, which are triggered by the ocean’s blue light, becoming visible to other swell sharks. David’s camera has special yellow filters that allow the simulation of a swell shark’s vision. It turns out there is a massive rave going on 500 metres below the ocean’s surface, and one of the glowing guests is a type of catshark!

Follow Lion Protector: Biologist Helps Big Cats And People Coexist The fewer than 2,000 lions left in Kenya face many threats, including retaliatory killings by herders who lose livestock to the big cats. National Geographic 2014 Emerging Explorer and conservation biologist Shivani Bhalla started a nonprofit, Ewaso Lions, to help herders learn to live with lions—giving the big cats their best chance of survival.
