WHAT IS WHALE PHOTO-IDENTIFICATION?
Photo Identification is a primary method for studying whales. “By photographing unique physical
characteristics of the whale, such as dorsal fin shape and body coloration patterns, researchers are able to
tell individuals apart within a population of a particular species.”(about.com)
Once a sighting record is established for an individual whale, researchers can study their movements, feeding patterns, migration, life span, age of maturity along with population estimates
