Our photo of the day comes from Bare Island, Australia. All hail Mother Nature and her creation of the ever-weird, ever-wonderful nudibranch, or sea slug. These creatures are some of the planet's most colorful ... and most adorable, as you can see in this shot of a Bennett's nudibranch (Hypselodoris bennetti), photographed by John Turnbull. John titled the photo "Meditation," and writes: "Well, it looks like it to me. Who's to say that a tiny hermaphroditic invertebrate can't indulge in a bit of meditation?"
