Saw this over at Deep Thoughts. A beautifully weird fish, the "barreleye", with upward pointing eyes under a transparent canopy of a skull. Another quirky player in life's mad pageant. This release from the Monterey Bay Aquarium Research Institute describes how researchers have discovered that these eyes can rotate to fix on prey (it was previously thought the eyes were fixed in their "barrels"), and that it might specialize in feeding on organisms trapped in jellyfish tentacles. The two duct-like bits above the mouth are nostrils.
