Orphaned mountain gorilla, Ndakasi, lies in the arms of her caregiver, Andre Bauma, on September 21, 2021 shortly before her death, which the park confirmed on September 26. Mr Bauma and others at the Senkwekwe Mountain Gorilla Center had cared for Ndakasi and other orphans for 13 years. Ndakasi had suffered a prolonged illness prior to her death. This is the only mountain gorilla orphanage in the world and takes in mountain gorilla orphans who have lost their families to poaching or conflict. A number of the orphans here were rescued from sales by poachers in sting operations carried out by Congolese National Park Authority (ICCN) rangers. (Photo by Brent Stirton/Getty Images)
