What's the difference between bliss and solace? Misery and sorrow? Bitterness and malice? In in way or another, animals experience many of the same emotions that humans do, with compelling and sometimes hilarious results. In the color photographs here, see yourself in the animal world with images of "indulgence" personified by a chubby-cheeked chipmunk, "glee" shown by a dancing tree frog, and "infatuation" portrayed by the entwined necks of two giraffes. Here too are caroling camels, an ecstatic orangutan, a grinning seal, snuggling otters, and an owl that looks like it is laughing out of sheer happiness.
