Okinawa

The deep, emerald waters surrounding Japan's Okinawa Islands are a haven for marine life, and is one of the most biodiverse ecosystems on the planet. Within this vast biodiverse haven, scientists have discovered two new species of pygmy squid lurking beneath the surface: the Ryukyuan Pygmy Squid and Hannan's Pygmy Squid.

These two species have now been described and catalogued, with names that connect them to Japan's cultural heritage. Findings have been published in the Marine Biology journal. 

The submarine was found by the Lost 52 Project, which locates lost U.S. World War II submarines, and is the first U.S. submarine discovered off the coast of Japan. Japanese records indicate that the sub was sunk by a 500-pound bomb dropped by a naval bomber in February 1944.
