Studies on the behavioural biology of Inia geoffrenses in captivity

This paper reported the various behaviours in two male Amaron dolphins, named "Vater" and "Baby", which had been kept at the Duisburg Zoo for 16 years. The behaviour of the dolphins in captivity is directly affected by the size of the pool. Different species of dolphins, with different body structures and in different habitat characteristics, have different behaviours: "Vater" and "Baby" show closer relations for emotional and physiological factors since they have lived together for 16 years
