I viewed the San Francisco zoo and I spotter and observed two primates species there: one is chimpanzee and second one is Lemur. Species 1: Chimpanzee There were both male and female chimpanzees. With the help of the guide, I could know the variation and differences between male and female chimpanzees. I observed that their bodies are covered with black hair. Males had larger faces than the females and males were robust. Apart from the black hair the skin color was mixture of pink and white for young ones and black or gray for adults, that is color of flesh.
