Rated • 34 reviews • animals • koko.org
The primary program of The Gorilla Foundation/Koko.org involves teaching American Sign Language to two lowland gorillas, Koko and Michael (who recently passed away). The Gorilla Language Project, or Project Koko, is the longest continuous inter-species communications project of its kind in the world, and it serves as a unique and irreplaceable resource for the international conservation community.
