A video of a man feeding a giant crocodile with his bare hands has gone viral. The footage shows the man, likely a trained professional, calmly feeding the massive reptile as if it were a domesticated pet. He is also not seen wearing any protective gear. The crocodile’s surprisingly docile behaviour sparked speculation among viewers about whether the reptile had been trained to respond in a controlled manner.
