In a bizarre incident, it is supposed to have activated a farts, the fear of Russian drones aimed at British nuclear submarines, causing a fear of safety off the coast of Scotland.
The unusual underwater sounds were detected twice by Marine sensors, which increased suspicions of enemy activities near the island of Raasay and AppleCross in northwestern Scotland.
It was initially feared that the sounds could be linked to one of the drone submarines from Vladimir Putin who plants a listening device on the seabed to follow the British naval activity.
The worries were serious enough to call on an urgent investigation.
A navy officer said to the sun: 'We have analyzed the sounds and now believe it was a marine mammal. A whale. '
But despite this assessment, not everyone is convinced.
Another military source added: 'We take it very seriously. We have to take the worst until we can be absolutely sure. '
The mysterious sounds were picked up for the first time to travel north from the submarine test range to the Open Sea.

A few days later the sounds came back, this time to the south to the Skye Bridge before they turn around and disappear.
Analysts initially described the sounds as people made, and emphasized that nothing like they were ever recorded in the 55-year history of the range.
Feeding this speculation that the Russian research unit in Deep-Sea, known as Gugi, could use advanced technology to record acoustic signatures of British submarines.
Such intelligence would make British Subs easier to follow, making an important threat to national security.
Added to the tension, two civilian ships were equipped with submarine robots in the 1000-foot deep channel around the same time as the alert.
Their presence aroused further concerns about potential Russian espionage.
However, seasoned navy experts quickly point out that underwater animal sounds, including whale course, are previously considered for enemy submarines.

Although this theory is supported by initial sound analyzes, the Navy remains careful, given the commitment involved.
The incident comes in the midst of growing fears for Russian interference in British waters.
This week, Minister of Defense John Healey gave a strict warning to Moscow, stating that Russian ships suspected of damaging British underwater cables are on board and seized by Royal Marines.
In a related event last November, a submarine of the Royal Navy appeared near a Russian espionage ship about critical submarine infrastructure in the English channel, which shows the vigilance of the navy in protecting the maritime interests of Great Britain.
A navy spokesperson emphasized the importance of constant monitoring and stated: “We constantly patrol our territorial waters to protect the UK.”
Although the mystery of the underwater sounds may turn out to be nothing more than a windy whale, the navy leaves nothing to chance because the tensions with Russia remain high.
