Oceans are vital to wildlife and our planet. Containing 99 percent of the living space on earth, oceans are vast habitats for an impressive array of life. To celebrate World Ocean Day, we’re sharing this remarkable picture of bioluminescent plankton near Haystack Rock at Oregon Coast National Wildlife Refuge. From moments like this to surfing, sailing, fishing and diving, oceans are essential to our lives, economy and natural understanding. Photo courtesy of Jeff Berkes.
