A dolphin’s fluke is like our fingerprints. No two are the same! Those little nicks, curves, and markings along the edge aren’t random, they’re unique to each dolphin and stay with them for life. Scientists use these natural patterns in their dorsal fins specifically to identify individual dolphins over time, estimate population size, as well as track health, family bonds, and movement. Once you notice it, you can’t unsee it. Every fluke or fin tells you exactly who you’re looking at! #dolphins
