Field ID guide
Individual humpback whales are identified by the pigmentation and shape of their ventral flukes (tail) as well as the shape of the dorsal fin. CCS has studied humpback whales using photo-identification and other research techniques since the 1970s. Learn more about our Gulf of Maine Humpback Whale Catalog and scientific research here.
A fluke photo-ID guide is available to the Gulf of Maine whale watching community. This guide contains only a subset of the whales that we have cataloged and is being shared online for educational use only.
