Humpback Whales: Fins Patterns like Fingerprints

Each year, between January and March thousands of humpback whales (Megaptera novaeangliae) regroup to reproduce in the waters of the north coast of the Dominican Republic.

Humpback whales distinguish for their charisma and acrobatics, and are easily identifiable by their stocky body and long pectoral fins. Humpback whales from the North Atlantic (Canada, do not Greenland, Iceland, USA) migrate to the Caribbean, entering Dominican Republic territorial waters, in areas such as Banco de la Plata, Banco de la Navidad and SamanĂ¡ Bay, places that stand out among the most visited by whales in the entire Caribbean region.

Of the three areas, SamanĂ¡ Bay is the most visited destination for whale watching in the country and is considered to be one of the best areas for such activity in the Caribbean and in the world, receiving approximately 50,000 visitors in 75 days.

Their “fingerprint”
What many people don’t know is that in 1977 it was discovered that the pectoral fins have unique pigmented patterns, which make individual whales identifiable.

As a result of extensive research, a catalog of thousands of whales identified by these colors is homed in libraries of universities and research centers all over the world.

So now you know! When you see a whale look at its tale and it would be like taking their fingerprint, making that specific whale unique and distinguishable.
