Our photo of the day reveals the wonders of cheek pouches.
Behold the marvelous chipmunk cheeks! (Not to mention those hands, my goodness.) Photographed by Richard Liebert, this smallest member of the squirrel family seems to be saying, "Nothing in these cheeks, nope, no food here."
But we know what's really going on.
Ed Spevak, curator of invertebrates at the St. Louis Zoo, tells National Geographic that chipmunks can transport food amounts as large as themselves in their oversized pouches; helpful, since they need their forelegs to run from predators. Although when they do, Spevak says, it’s like running “with a fanny pack around your mouth.”
