Negra was captured as an infant in the forests of Africa. The vast majority of her 36 years have been spent in a laboratory where she was used in hepatitis vaccine experiments and for breeding. Negra now lives at the Chimpanzee Sanctuary Northwest where she has a nightly ritual of wrapping herself in a blanket and peeking out at her companions. Negra is one of seven chimpanzees, including Annie, Burrito, Foxie, Jamie, Jody, and Missy, who are the first residents of the sanctuary.
PCRM scientists met Negra as they continued their observation of the long-lasting psychological damage to chimpanzees previously used in laboratories. The Great Ape Protection Act would phase out all invasive research on chimpanzees and release federally owned chimpanzees to permanent sanctuaries.
