One of seven images in a row showing a humpback whale rising up from the depths to do a bit of kelping. Kelping refers to an animal intentionally "playing" with Macrocystis, Pelagophycus, Nereocystis or other kelp species that are detached and drifting on the surface. Humpbacks are thought to have very sensitive skin and seem to "enjoy" this experience.
