Whale Identification There is sufficient variation in the markings of humpback whale flukes (the lobes of the tail) to allow photo identification of individual whales. Curt, your...Stage 1 involved digitising the existing photo-identification catalogues of the Centre for Whale Research (WA) Inc., which totalled over 3,000 images at that time.Stage 2 involved categorising and grading each digitised photograph for use with a computer programme developed specifically for matching humpback whale tail flukes by the National Marine Mammal Lab (NMML, NOAA),. ).As a whale’s exhalations from their blowhole condense in the air, they create shapes that are unique to each species and are helpful for identification.
