San Francisco: America’s oldest male chimpanzee, living at the San Francisco Zoo and Gardens, died on Saturday. He was 63 years old. The name of the chimpanzee was ‘Cobby’. She was cared for by a man before being brought to the San Francisco Zoo in the 1960s. A press release issued by the zoo said that the cause of the chimpanzee’s death is not yet known, but officials believe that its aging may be the reason.
The International Union for Conservation of Nature has listed the chimpanzee as an endangered animal. They are considered the most threatened primate species in Africa due to hunting, habitat loss, and disease. The zoo reported that 100,000 to 200,000 chimpanzees living in the wild have an average lifespan of 33 years, compared to 50 to 60 years when cared for by humans.
