Bowriding Dall's

August, 2007
Dall's porpoise are among the fastest of all cetaceans on the planet, capable of bursts of speed of almost 40 miles per hour. The two porpoise pictured here are bowriding in Chatham Strait, southeast Alaska. The water is so perfectly clear and flat that the image of me hanging over the bow is reflected back to the camera.

In this image note how the water around the body of the porpoise is being "lifted" as the porpoise surfaces to breathe. This is causing the ship's bow to appear to divide into two equal parts. The correct ship's bow shape is reflected in a second mirror image within the body of the porpoise itself. Serendipity at its best!

A perfect "barrel" of water caused by the splash from this Dall's porpoise surfacing to breathe.
