But far from being scared, Mr Korostelev was delighted with his deadly encounter.

He said: 'It was not an accidental meeting, the main purpose of my trip was to capture an American crocodile in its natural environment.

'I met this crocodile underwater face to face. When it swam close to me, the only thought I had was about how great it was that I could take great pictures.

'It nuzzled into the camera several times and sometimes it touched me with its tail.'
