PHILADELPHIA (KYW Newsradio) -- A rare primate has been euthanized at the Philadelphia Zoo. 

Toi, a 21-year-old female Red-shanked Douc Langur, was put down because of a variety of age-related illnesses. The monkey, endangered in the wild, was the last of its species in all of North America.

Dr. Andy Baker, Chief Operating Officer at the Philadelphia Zoo, says the primate was an ambassador to all animals endangered in the wild.

"[She's] a reminder of all the amazing animals found around the globe that find themselves facing survival challenges," Baker said, "and all that we can do from decisions from consumer choices to our resource use that really do reverberate across the globe and affect many, many amazing animal species."

Douc Langurs are native to the rain forests of Vietnam and Laos.
