One ocean connects us all

This World Ocean Day, we are celebrating the global ocean that connects us all. The deep sea is the largest living space on Earth. Weird and wonderful animals thrive in this cold and dark environment. Between the sunlit surface and the deep seafloor lies an expanse of open water—the midnight zone.
