There are more than 1,000 chimpanzees remaining in US laboratories; most have been there for decades. The HSUS is seeking to end the use of these endangered animals for invasive research and testing in the United States (the only country, besides Gabon, that continues to use chimpanzees for harmful research). In addition, we want to ensure that the chimpanzees currently in laboratories are retired to appropriate sanctuaries. To learn more about our campaign and chimpanzee use in research, visit www.humanesociety.org/chimps.

Watch the video and read about the recent HSUS undercover investigation into the largest chimpanzee research facility in the world.

Chimpanzees have amazing memories. Take a look at this video below of a chimpanzee involved in noninvasive behavioral research at the Primate Research Institute, Kyoto University. To set this up, in order to get a treat, the chimpanzee must touch the numbers in order from lowest to highest. But, there's a catch! The moment the chimpanzee touches the first number all of the others are covered and the chimpanzee must remember which numbers were where!
