This is an amazing cooperative behavior in which a couple of humpback whales dive deep in fish rich waters.  They then begin blowing bubbles which form a bit of a wall or net as the bubbles rise to the surface.  This “net” concentrates small fish near the surface of the ocean.  Then the whole group of humpbacks rise up in the middle of this concentration with mouths wide open as they feed on all the fish.  If you look close, you can see fish leaping out of the water in an attempt to escape the whales.  It is fascinating to watch.
