CRC-12307 @2479
CRC-12307 has one of the most striking cases of changing flukes from juvenile years to adulthood. Note how pale the fluke was in the first known sighting, from 2007, and the trailing edge has changed significantly as well, becoming much less featured. This whale is known from research conducted by Cascadia Research Collective and collaborators.
