LEGEND: Ryujin

For thousands of years, different cultures have talked about serpent-like creatures that resembled dragons. In Japan they had a name for it — Ryujin — who lived in a coral palace at the bottom of the sea, with jewels that could raise and drop the tide, and a bloodline that ran straight into the imperial family. Some say it’s folklore. Others think there might be a scientific explanation. One that makes the idea dragons seem not so far fetched after all.
