Climate Change Hits Big Fish Hard

0:00That wraps Europe news today brought to you with AI. I'm Cory with the story. Ireland's basking sharks and fish, like great whites and tunas, are in hot water from climate change. A new study out of Trinity College Dublin shows these warm-bodied swimmers burn up to four times more energy than cold-blooded ones. As oceans warm, their bodies heat up fast, forcing them to eat way more just to keep going. Researchers teamed up with the University of Pretoria to track this using tiny sensors on free-swimming fish, even massive basking sharks weighing up, to 3.5 tons. They found a 10-degree Celsius jump and body temp more than doubles the metabolic rate. Bigger fish get warmer naturally because they hold heat better than they lose it. Scientists call it double jeopardy. These high-performance predators already deal with overfishing on themselves and their prey. Warmer seas mean less food and shrinking habitats, pushing them toward the poles or deeper, cooler waters. The study, dropped in the journal science, predicts summer hot spots will vanish for

Past giants like the Megalodon shark, crashed during climate shifts, and now oceans are changing quicker than ever. This lines up with why big fish stick to cooler zones or migrate seasonally. As waters keep rising, these ocean elites face real survival tests, reshaping marine life as we know it.
