It is difficult for sloths to see from the outside whether it is a male or female. That’s why it took a while before it became clear which sex the young had. To find out, a DNA test was performed. “Now that Diego is independently exploring the enclosure and is no longer always lying on his mother’s stomach, we were able to remove a hair. The mother is very protective of the young at the beginning. We want to prevent unrest, so we waited for the moment he started researching independently,” explains animal caretaker Christel Broekman.
