The United States Defense Advanced Research Projects Agency (Darpa) in Arlington, Virginia, has been researching the use of electronic implants to control the movement of sharks.Boston University has developed brain implants that can influence the movements sharks by "steering" them using a phantom scent.
Electrodes are attached to the region of the shark brain associated with scent detection.
When the stimulus is to the right side of the olfactory centre the fish turn right, when it is left, the fish swim left.
According to New Scientist Magazine: "By remotely guiding sharks' movements, the military hopes to transform the animals into stealthspies, perhaps capable of following vessels without being spotted. The Pentagon hopes to exploit the ability of sharks to glide quietly through the water, sense delicate electrical gradients and follow chemical trails."
A shark has been at work in Sharm el Sheikh in Egypt.
There is speculation that Mossad may have placed the shark in the area.
Mohamed Abdel Fadil Shousha, the regional governor, has claimed it is not "out of the question" that Israel planned the shark attacks on tourists to hurt the Egyptian economy.
He said: "What is being said about the Mossad throwing the deadly shark in the sea to hit tourism in Egypt is not out of the question. But it needs time to confirm."
Shark 'sent to Egypt by Mossad'
Speaking on the TV program "Egypt Today", "Captain Mustafa Ismail, a diver in Sharm El Sheikh," said that the sharks involved in the attack are ocean sharks and do not live in Egypt's waters.
When asked how the shark entered Sharm El Sheikh waters, he said "no, it's who let them in?"
Ismail said that he recently got a call from an Israeli diver in Eilat telling him that they captured a small shark with a GPS (Global Positioning System) planted in its back.
"Why would these sharks travel 4000 km and not have any accidents until they entered Sinai waters?" asked Ismail.
Mahmoud Hanafy, from the Suez Canal University, pointed out that actually there are oceanic white tips in Egyptian waters. (Mossad Behind Egyptian Shark Attacks?
