"Koko was reported to have a preoccupation with both male and female human nipples, with several people saying that Koko requested to see their nipples. In 2005, three staff at The Gorilla Foundation, where Koko resided, filed lawsuits against the organization, alleging that they were pressured to reveal their nipples to Koko by the organization's executive director, among other violations of labor law. The lawsuits were settled out of court. Gorilla expert Kristen Lukas has said that other gorillas are not known to have had a similar nipple fixation.[43][44][45][46][47][48][49]"
