Sailfish

The sailfish is known as the fastest fish in the oceans, capable of reaching 110 km/h in sprint. Its enormous dorsal fin deployed like a sail — from which its name derives — allows it to herd schools of fish before spearing them with its sharp bill. In Mexico, from December to March, sailfish hunt in spectacular groups in the warm waters of the Yucatán — a scene that DUNE captures while snorkeling during its special stays in Islas Mujeres.
