It was a typical summer day in the Sant Ocean Hall at the National Museum of Natural History. Visitors were examining the giant squid and marveling at the life-size replica of Phoenix, the right whale. The only thing odd was the high number of blue-clad people milling about. 

And then surfing-music filled the gallery. 

The blue crowd began to jam out. A Roundnose Grenadier and orange roughy -- both from the deep sea -- joined in. The "splash" (flash) mob lasted a couple minutes and ended with bystanders and dancers alike doing the wave. Happy World Ocean Day!
