Here are three potential cover photos for Zoobooks Apes, our January issue–please comment and let us know which one you find most appealing. Not all apes are represented here, because there are several species: gorillas, orangutans, chimpanzees, bonobos, gibbons, and siamangs–whew, that’s a lot! Maybe it’s a good thing we aren’t including monkeys, too. (What’s the most obvious difference between a monkey and an ape, by the way? The answer is, apes don’t have tails.)
