The Common Chimpanzee (Pan troglodytes), also known as the Robust Chimpanzee, is a great ape. The name troglodytes, Greek for 'cave-dweller', was coined by Johann Friedrich Blumenbach in his Handbuch der Naturgeschichte (Handbook of Natural History) published in 1779. Colloquially, it is often called the chimpanzee (or simply 'chimp'), though technically this term refers to both species in the genus Pan: the Common Chimpanzee and the closely-related Bonobo, or Pygmy Chimpanzee.

Some animals are surprisingly sensitive to the plight of others. Chimpanzees, who cannot swim, have drowned in zoo moats trying to save others. Given the chance to get food by pulling a chain that would also deliver an electric shock to a companion, rhesus monkeys will starve themselves for several days.

The survival of the great apes is threatened by their being hunted for food to satisfy ex pat communities that consider them a delicacy.
