CNN followed an international group of whale authorities all over 2023, from Friedlaender’s lab within the College of California at Santa Cruz to humpback breeding grounds from the Pacific Coastline of Colombia, трип скан as well as their feeding grounds at The underside of the world.

The workforce interacted with dozens of whales about the system of four times in Antarctica. They utilised specialized digicam drones to measure body dimensions and suction-cupped tags slapped onto the animals’ backs which has a very long pole to file the way they shift although capturing whale’s-eye-see online video.
“And that’s what feeds the food stuff for whales, birds, seals — anything. They’re fundamentally farmers recycling nutrients and there’s more food items available to them the greater they’re close to.”
But almost a 50 percent-century later, the comeback with the humpback is arguably the greatest achievements story during the historical past of conservation.
