This is the first picture taken of the Macropinna microstoma or “Barrel Eye” fish. This strange little guy has a transparent head so it’s eyes can rotate back and it can see right through it’s “dome” and see what’s going on above.
“Barreleyes typically live near the depth where sunlight from the surface fades to complete blackness. They use their ultra-sensitive tubular eyes to search for the faint silhouettes of prey overhead.”
Scientists have known about ol’ Barrel Eye since 1939, but until 2004 have only seen mangled bodies dragged to the surface by fishing nets. This picture taken in 2004 in the deep water off California's central coast by the Monterey Bay Aquarium Research Institute (MBARI), but was just released yesterday.
