    Fluke Matching
     
    This humpback whale was photographed by PCCS scientists working on Stellwagen Bank. Try to identify the whale by comparing its fluke to images of four previously cataloged humpback whales. Click here for matching instructions and tips. 
     
    Fluke to match
     

    You are correct!
    This is Iota, a female that was first cataloged in 1988.

    If you look at the photograph again, you will notice that Iota acquired new scrapes along her trailing edge since her most recent catalog photograph.  Small changes like these can accumulate over time, making it more difficult to identify individuals. The more frequently the catalog is updated, the more efficient is the matching process.
