Octopuses are fascinating creatures. Their invertebrate bodies are capable of squeezing through tiny cracks, and they can change color and taste with their suckers, among other things. To photograph them for the November feature story "Why Do Octopuses Remind Us So Much of Ourselves?" David Liittschwager briefly placed a variety of species—such as this southern keeled octopus—inside an aquarium placed in front of a white background. "I love to watch how curious they are," says Liittschwager, adding, "They are escape artists. You really have to keep an eye on them."

Here, we are treated to the marvel of this fellow in action.
