Vitorino De Araujo (37) slowly approaches a large crocodile in swamplands on the outskirts of Lospalos, as scientist Yusuke Fukuda watches over his shoulder. Victorino is a local from Lospalos and a crocodile specialist who people consider to be a spiritual leader. He works with a team of scientists from Australia, trying to take DNA samples from crocodiles by spearing them with a needle on the end of a biopsy poll. ''It's like a mosquito bite, they don't feel it'', Yusuke says about the process. The researchers usually prefer working at night, mainly because it's much easier to spot a crocodile with torch light at night and also because the animals are often stunned by the head torches and are less aware of the men's movements.
