The Humpback whale vertically pops its head out of the water with its mouth closed.  It is believed that this behavior allows the curious male whale to view activity above the surface of the water.  Many of our whale watching raft expeditions on Kauai will encounter whales spy hopping on our passengers, as if the whales are people watching.  It is curiosity? Perhaps.
