One of the things that I learned on this trip, was that humpback whale tails are as unique as a human fingerprint.  Whale researchers have used this method of identification as a way of tracking the movements of individual whales.  There is a "Whale College" of researchers that encourages anyone who manages to get a picture of a humpback tail, especially in the Southern Hemisphere, to send in the picture so that it can be matched against others in the catalogue.  If a match is found, then a copy of the migration pattern of that particular whale is sent to the person that took the picture.

Using this method, some humpback whales have been tracked from Antarctica to as far as the Caribbean!
