Male North Pacific humpback whale streams a trail of bubbles. The primary male escort whale (center) creates a curtain of bubbles underwater as it swims behind a female (right), with other challenging males trailing behind in a competitive group. The bubbles may be a form of intimidation from the primary escort towards the challenging escorts.
