World’s deepest “blue hole” discovered

It’s located near the Xisha Islands (also known as the Paracel Islands) in the South China Sea.

(Blue holes are underwater caverns or sinkholes, typically formed in shallow seabeds made of carbonate rock such as limestone. They can be hundreds of feet deep, and much deeper than surrounding waters, leading to dramatic photographs as seen here.)

According to Xinhua News, Dragon Hole, or Longdong, is 987 feet (300.89 meters) deep, far deeper than the previous record holder, Dean’s Blue Hole in the Bahamas.

Scientists discover a solid-black, bio-luminescent shark

As if the creature’s physical characteristics weren’t interesting enough on their own, researchers gave it one of the coolest names in the animal kingdom: the ninja lanternshark. This shark can be found in the deeps off the Pacific coast of Central America, and grows to about 1.5 feet in length.

Like other lanternsharks, it produces light with special organs in its body, which is likely used to communicate with other sharks, for camouflage and perhaps to attract prey. The scientists who first found the fish, from the Pacific Shark Research Center in California, gave the species the technical name Etmopterus benchleyi. It’s named after Peter Benchley, the author of Jaws. […] The animal lives in the waters off the continental slope, at depths of 0.5 to 0.9 miles deep, where it is very dark. It presumably eats small fish and crustaceans although scientists don’t yet know hardly anything about its diet or behavior.
