According to the daily mail of June 30, Riccardo stulla avogadri, a shark expert, can hypnotize a shark underwater by gently touching its nose for close observation.
Kaldor called his method of hypnotizing sharks' relaxation and rest '. Although he can successfully use this hypnotism to transform the 'sea tyrant' into a 'gentle sheep', he still wears wire gloves to protect himself from being bitten by sharks. And before using shark hypnosis, he had to be careful to get close to the shark before touching the shark's nose to hypnotize it.
Once the shark is hypnotized, caldo says, he and his colleagues can really get in touch with it. They have successfully observed 50 grey reef sharks with this method. They become very calm under the Kaldor massage, in a trance state, can be manipulated, take photos at will.
