A surface lunge feeding humpback whale (Megaptera novaeangliae) is seen from below the "chin." The grooves in the ventral blubbler are distended and expanded. The whale is also spouting. A common dolphin (Delphinus capensis) and a sooty shearwater (Puffinus griseus.) are also seen in the picture. There are numerous stalked barnacles growing attached to the ventral surface.
