In this photo, taken in 2009, but not made available until Thursday March 3, 2011, a diver is seen close to a sunken submarine discovered south of the island of Gotland, Sweden

Another Soviet Sub found in Swedish waters

However, Swedish Navy spokesman Capt. Bo Rask said Thursday there were no signs the submarine had been damaged by weaponry, but a metal wire

The submarine, a Whiskey-class vessel from the 1950s that was once common in the Soviet navy, was discovered by chance during a seabed survey.

The wreck lies on the seabed in the Swedish economic zone. Some hope that the find will finally prove that Sweden were subject to repeated intrusions by former Eastern bloc submarnes during the 1980s.

Lemon shark on its merry way

Sharks know where they are going

Using statistical analysis, researchers have demonstrated that the journeys of three species—tiger, thresher, and blacktip reef shark—were not made by accident; the sharks followed some kind of path.

Scientists analysed data from tiger sharks tagged with acoustic transmitters and found they took directed paths from place to place. Other species, such as blacktip reef or thresher sharks, did not show this behaviour.
