Scientists have confirmed the second-ever case of virgin shark birth indicating that female sharks can reproduce without mating with a male shark. The possibility exists that many female sharks have this incredible capacity. Through DNA testing, a team of scientists has proven that the offspring of a female blacktip shark, named Tidbit, had no genetic material from a father. Tidbit has lived for eight years at the Virginia Aquarium in the Norfolk Canyon Aquarium since shortly after her birth in the wild, according to a statement from Stony Brook University.

Two surfers were simultaneously bitten by sharks over the weekend in an area not far from where a father and son later that day survived more than 13 hours floating in the water until rescued - without being bitten. The shark bite victims were both sitting on surf boards in the water about 200 feet apart and were bitten on the foot in two separate incidents about a second apart, according to reports.

The bodies of more than a dozen hammerhead sharks were recovered from an illegal gill net in Kane'ohe Bay, a mating area for hammerheads near the Waikalua Fish Pond. All the sharks were pups and they were found by a Nature Conservancy team on patrol in the area on Thursday.

A small seaside community is for a 21 ft. great white shark swimming in the local lake. A fisherman netted the shark in Tuggerah Lake, which opens to the Pacific Ocean 60 miles north of Sydney, but when he realized the shark was bigger than his 18-foot boat he let it go.

A device attached to surf boards to repel sharks and protect surfers from getting attacked by the sea predator failed during an actual test off South Africa on Friday when a great white shark ate it. The failure of the Shark Shield's emitted electric field to deter sharks from approaching the board caused the sale of the device manufactured by Australian firm Shark Shield Pty. Ltd. to be suspended.
