It's an incredibly difficult and dangerous job. During their ten days, the men bent several needles and had their biopsy poll bitten by the wild animals. The local knowledge of crocodile expert Vitorino De Araujo was critical to the success of the research trip: One day, he managed to get seven DNA samples.
