Snapshots from Zihuatanejo - Humpback Tale a Fluke?

In what surely must be among the strangest whale photos ever shot, a mother humpback whale and her calf frolic in the Pacific north of Ixtapa. I watch both breach a dozen times. Between the electrifying leaps, both casually wave their fins and then smack them down on the water.

But then, in an instant, there is this curious study in the unison of opposites. The calf's smooth, jet black body completes a fluid leap, just as the cow raises her gnarled, graffitied flipper as if to show her approval.

Both forms, with little evident splash, look for all the world as if they'd been copied and pasted onto an empty sea. In perfect alignment, they appear to be the same size, but somehow it all looks impossible. It is not.
