Primate Info Net

Primate Info Net (PIN) provides resources about non-human primates in research, education and conservation. Its PIN forums support an informal “primate information network” comprised of thousands of individuals working with, or who wish to work with nonhuman primates. PIN is a community effort and we’d love to hear from you! If you notice something missing, would like to contribute, or have any questions, please contact us.

Have a question? Ask Primate!
April 16, 2024 alert: Ask Primate (PIN Mail) is down. We will keep you posted here when it is back up and running! In the meantime, please write to us here.
