Seemed like a good day to run a photo I took a year or so ago, but what kind of terrible sea monster is it, rising from the ocean, jaws agape?
Truth is, it’s a humpback whale about to splash back into the water. The ‘lower jaw’ is really a pectoral fin. The ‘spiky teeth,’ are tubercles, knobby bumps on the fin’s leading edge. The ‘upper jaw’ is the lower jaw seen from below. And the ‘eye’? Well, that’s an eye, no fooling.
For more information about humpback whales, I recommend Jim Darling’s book, Humpbacks: Unveiling the Mysteries or go to whaletrust.org or hawaiihumpbackwhale.noaa.gov/welcome.html.
