In a rare video, captured by the science-focused Rebikoff-Niggeler Foundation and first released as a Science Magazine exclusive, a female fanfin sea devil slowly pitches back and forth in the inky, cold waters 2,600 feet under the surface of the North Atlantic.

Whereas membrane-connected filaments in other fish species move as a single unit, the glowing ones on the fanfin sea devil appear to function independently, each equipped with its own set of muscles and nerves.

A fine athlete, Bailar joined the Sea Devil swim team at age 9 and the Nation’s Capital Swim Club team at age 15.

It is a large species of the Eagle Ray that is known as the Sea Devil of the tropics.

By contrast, fish like the Black Sea devil, another marine star of the exhibition, are positively disturbing in appearance.
