Veterinarian William Guerra Neto (2nd L) and his assistants take measurements of one of two Amazonian manatees who are being rehabilitated after sustaining injuries from hunting and fishing nets at the Center of Amazonian Manatees at Amana Lake in Maraa, Amazonas state, Brazil, September 21, 2015. The Amazonian manatee is relatively easy to hunt, and is threatened as a result. It is also at risk from pollution, accidental drowning in commercial fishing nets, and the degradation of vegetation by soil erosion resulting from deforestation, according to the Center of Amazonian Manatees.
