When you come on a tour, you might notice the crew getting excited about a specific whale tail. That’s because looking at a whale’s tail (the fluke) is exactly like looking at a human fingerprint. No two tails in the world are identical. Scientists and enthusiasts use these markings to track individual whales across the globe, telling us exactly who is visiting Samaná Bay this year.
The underside of the fluke can range from all white to all black, with every variation of patches and scratches in between. These markings are permanent. By photographing them, researchers have created catalogs that tell the life stories of specific whales—some of whom have been returning to the Dominican Republic for over 30 years!
The three keys to Whale ID:
Pigment Pattern: The ratio of black to white skin on the underside of the tail.
The Trailing Edge: The back edge of the tail can be smooth, jagged, or have specific “bite” shapes.
Scars: Distinctive scratches, often caused by interactions with other marine life or even Orcas.
Next time you see a tail rise out of the water before a deep dive, remember: you are looking at a unique identity, a specific individual with a history as deep as the ocean.
