Old monkeys display some characteristics relevant to their age. Average lifespan at Monkey Forest is 23 years, but our oldest monkey was 32, that’s over 100 in human years! ! We have a few monkeys in the park living way past the average age.
Old monkeys move slowly, can become thin or frail and need lots of rest. Their spine can become curved over time. Old females have black fur around the face like a beard.
