Both SHARKS and RAYS have skeletons that are made entirely of cartilage (the hard part found in the middle of your nose). Sharks are the oldest known jawed animals on Earth, having evolved nearly ½billion years ago.

Despite human's fear and distrust of these ancient animals, only 4 people are fatally attacked by sharks each year. Conversely, 100 million sharks are killed by humans annually. An Ocean Love Story.

A rare megamouth shark just washed up in the Philippines

Today, a rubbery-lipped, 15-ft. (4.5 m) beastie washed up on a beach in the Philippines. The creature turned out to be a megamouth shark—a species so rare that Christopher Bird, a marine zoologist and blogger, has estimated it’s only the 60th confirmed human encounter with one. Before 1976, no one had any idea megamouths existed (officially, at least). It was in Hawaii that year that a 14.6-footer gulped down a submerged parachute filled with sand, which a US Navy ship was using as an anchor. Scientists were as baffled as the crewmen: though loosely related to two other, mostly vegetarian, shark behemoths—the whale shark and the basking shark—the creature belonged to a previously unrecognized family, genus, and species.

Its family tree has something to do with its comically gaping maw. The rarity of sightings is one thing that still confounds Bird and other marine scientists.

Mr Downs gave the sharks to a group of researchers at the Oceans the University of Western Australia.

It was the winner of ‘Underwater World’ category at the 2010 Environment Photographer of the Year awards organized by CIWEM. German photographer Florian Schulz said the scope of the ray congregations was unknown until he and a pilot happened upon the gathering while searching for migrating whales. The International Union for Conservation of Nature lists Munk’s devil rays as near threatened, due in part to their vulnerability to gill nets—hard-to-see “curtains” of netting.

Great white sharks back in Red Triangle. Scientists are all but running giddily into the surf with fancy new gadgetry as the annual migration of great white sharks hits full swing along the Pacific coast and reports flood in about finned beasts lurking in shallow waters.

Great white sharks back in Red Triangle

The ferocious predators have returned to their feeding grounds in the so-called Red Triangle, an area roughly between Monterey Bay, the Farallon Islands and Bodega Head, but sharks have been spotted all along the coast, including a 20-footer seen last weekend next to Moss Landing Harbor. The appearance of the great whites could not come at a better time for researchers, who recently deployed a new robotic device that can identify and track the movements of sharks and other fish equipped with acoustic monitoring devices. The new robot, called the Wave Glider, is a solar-powered device with a satellite hookup developed by Sunnyvale's Liquid Robotics. Monitoring program Some of the northeastern Pacific adults also hang out near Guadalupe Island in Mexico.

Cyclops Shark & Other Cryptic Creatures

But the Cyclops shark, sliced from the belly of a pregnant mama dusky shark caught by a commercial fisherman in the Gulf of California earlier this summer, is by all reports the real thing. Shark researchers have examined the preserved creature and found that its single eye is made of functional optical tissue, they said last week.

It's unlikely, however, that the malformed creature would have survived outside the womb. "This is extremely rare," shark expert Felipe Galvan Magana of Mexico's Centro Interdisciplinario de Ciencias del Mar told the Pisces Fleet Sportfishing blog in July. "As far as I know, less than 50 examples of an abnormality like this have been recorded. " Great White Shark Attack. Basking Shark. The 10 Largest Sharks In The World.

World-first hybrid shark found off Australia

The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan. "It's very surprising because no one's ever seen shark hybrids before, this is not a common occurrence by any stretch of the imagination," Morgan, from the University of Queensland, told AFP. "This is evolution in action. " Colin Simpfendorfer, a partner in Morgan's research from James Cook University, said initial studies suggested the hybrid species was relatively robust, with a number of generations discovered across 57 specimens. It means the Australian black-tip could be adapting to ensure its survival as sea temperatures change because of global warming.

Today’s bloodbath bulletin concerns whale sharks, which feed on plankton and can grow up to 40 feet (12 meters)—about the length of four station wagons. The shark is so vulnerable to extinction that most countries forbid fishermen from catching them. That’s not stopping a factory in China’s Zhejiang province from slaughtering 600 whale sharks per year, according to Hong Kong-based conservation group WildLifeRisk. The factory pays up to 200,000 yuan ($31,000) per whale shark (pdf), as WLR reports, and there’s now a global network of fishing boats that will sell them to the factory that WLR investigated. Why? ​ WildLifeRisk The plant exports at least 300 tons (272 tonnes) a year in oil leached from the livers of whale, blue and basking sharks, the manager, Li Guang, told WLR in this video (it’s not clear he was aware that he was being recorded).
