INTERACTIONS BETWEEN CALVES OF AMAZONIAN MANATEES IN PERU: A STUDY CASE
Trichechus inunguis is an endemic species of the Amazon, which inhabits mainly in lakes and calm rivers. The objective of this study case was to describe the social behaviour of two female-orphaned calves, of T. inunguis in captivity. They were kept in the same pool at the facilities of the Amazon Rescue Center (ARC, Iquitos, Peruvian Amazon).
