A gull stands on the rostrum of a feeding humpback whale hoping to snatch a sand eel missed by the feeding humpback in the Stellwagen Bank National Marine Sanctuary May 10, 2018 near Gloucester, Massachusetts. The humpbacks were feeding on sand eels by utilizing the bubble net method to trap the eels and then swimming up through it with their mouths open. (Photo by Don Emmert/AFP Photo)
