How a Storm Became Big Enough to Span the Atlantic

A new kind of lake monster has been found, in the depths of Lake Tahoe: gigantic goldfish. Researchers trawling the lake for invasive fish species scooped up a goldfish that was nearly 1.5 feet long and 4.2 pounds.
“During these surveys, we’ve found a nice corner where there’s about 15 other goldfish,” environmental scientist Sudeep Chandra of the University of Nevada, Reno, told LiveScience. “It’s an indication that they were schooling and spawning.” The arrival of the fish, which were probably dumped there by aquarium owners, has Chandra worried — goldfish are an invasive species that could interfere with Lake Tahoe’s ecosystem.
It’s unclear whether the giant fish were introduced as fully grown adults, or while they were still small, Chandra said. But even a small creature can have a big impact, if there are enough of them.
How’s this for a bundle of joy? This October, eight snakes with tentacles were born at the Smithsonian’s National Zoo.
It was not a Halloween prank. Zoo staff had been trying to breed the rare aquatic snake Erpeton tentaculatus for four years before success. These bizarre Southeast Asian serpents are the only snakes with two little tentacles on their snouts. These tentacles act like whiskers to help the snakes sense vibrations from swimming fish.
Amazing ‘Fairy Circles’ of the Namib Desert
Mysterious RingsCredit: Image courtesy of N. JuergensFairy circles are circular patches of perennial grasses with a barren center that emerge in the deserts along the southwest coast of Africa. Dotting the Namibian deserts, these rings can persist for decades and occur in regular patterns. Now, research detailed in the March 29, 2013, issue of the journal Science suggests a species of sand termite (Psammotermes) may be the artists behind the grassy artwork.

Two Headed Shark:
Experts say the discovery of a two-headed shark may be a world first. The sea creature was found when a fisherman working in the Gulf of Mexico cut into the uterus of an adult shark. The shark has two hearts and two stomachs but only one tail http://www.livescience.com/video/
