NUMAZU, Shizuoka Prefecture–A mirror dory, a rarely seen deep-sea fish species, was photographed swimming near the surface off Cape Osezaki here.
The images were snapped by Kazushige Horiguchi, 32, a photographer who lives in Nishi-Izu, also in Shizuoka Prefecture.
He received a report about â€śa rarely seen fish being spottedâ€ť on Jan. 14, and then discovered a young mirror dory measuring 3 centimeters long swimming just below the surface.
Its silver body shone in the bright sunlight like a mirror, as the speciesâ€™ name suggests.
Horiguchi, who has long been a diving guide, said it was the first time he has seen a live mirror dory.
Mirror dories usually live in waters 200 to 800 meters deep.
Young mirror dories have black-spotted bodies, but the spots disappear when they become fully grown, turning the whole body silver.
