With a head like a fighter-plane cockpit, a Pacific barreleye fish (Macropinna microstoma) shows off its highly sensitive, barrel-like eyes—topped by green, orblike lenses. This particular fish, discovered alive in the deep water off California’s central coast by the Monterey Bay Aquarium Research Institute (MBARI), is the first specimen of its kind to be found with its soft transparent dome intact. The 6-inch (15-centimeter) barreleye had been known since 1939—but only from mangled specimens dragged to the surface by nets (until this picture was taken in 2004). It is the only species of fish in the genus Macropinna, belonging to Opisthoproctidae, the barreleye family. It is recognized for a highly unusual transparent, fluid-filled dome on its head, through which the lenses of its eyes can be seen. The eyes have a barrel shape and can be rotated to point either forward or straight up, looking through the fish’s transparent dome.
"To me the sea is a continual miracle; The fishes that swim–the rocks–the motion of the waves–the ships, with men in them, What stranger miracles are there?"
