FEATURE: Beeindruckende Unterwasser-Welt in Palau
Pink Anemonefish, Amphiprion perideraion, Turtle Cove, Micronesia, Palau
The Pacific island nation of Palau has become home to the sixth largest marine sanctuary in the world.
The Micronesian reserve, now the largest in the Pacific, will permit no fishing or mining. Palau also established the world's first shark sanctuary in 2009.
The tiny island nation has set aside 500,000 square kilometres -- 80 percent -- of its maritime territory, for full protection. That's the highest percentage of an exclusive economic zone devoted to marine conservation by any country in the world. (FOTO: DUKAS/PHOTOSHOT)

Underwater Electric Light Show
These underwater corals look stunning as they emit a fluorescent glow of green, orange and purple.
The colours radiate from the coral in the same way a UV light bounces off bright clothing in a nightclub.
British photographer Alex Mustard, 36, snapped the glowing corals, worms, anemone and crabs while diving in the Red Sea and the Caribbean.
He took the pictures at night and used a standard camera fitted with a blue flash, which triggers the fluorescent reaction.
The exact reason why the corals fluoresce is a mystery but it is thought the fluorescent pigment acts like a sun screen.
Alex, from Southampton, Hants, said: "The Red Sea and the Caribbean both have healthy and rich coral reefs.
"For these types of images you want to photograph where there are lots of species of corals as some glow with fluorescence and some do not.
"What is amazing is that you don't know what you will get until you see the pictures.
"Some corals glow strongly, while others do not.
"It is only when you take the picture and the blue flashes go off that you know if the coral is a performer.
"The pictures are taken with a normal camera and the colours are those that the camera recorded. They are not adjusted on a computer.
"I fitted filters to my flashes so they produce only deep blue light.
"This excites the fluorescence response in the corals, which then give out the greens, oranges and yellows you see in the images.
"The effect is the same as when bright colours in your clothes show up under the UV light in a disco or nightclub."
He added: "Corals are important creatures, which build the reefs that support whole ecosystems.
"They are under threat from rising sea temperatures and increasingly acidic seas.
"But they are not always the most e...
