Chimpanzee faces are pinkish to black, and the apes' bodies are covered with long black hair.
Chimps lack a tail. Their opposable thumbs and toes help them grasp objects easily. Standing approximately 4 feet high, males weigh between 90 and 120 pounds, while females weigh between 60 and 110 pounds. An estimated 100,000 to 200,000 chimpanzees remain in the wild. Chimpanzees rarely live past the age of 50 in the wild, but have been known to reach the age of 60 in captivity.
