Sharks, rays, and skates have been on this planet for more than 400 million years, surviving mass extinctions that wiped out entire branches of life. Yet in just a few decades of human excess, many of these species have been pushed to the brink. They are not only hunted and killed deliberately but also dragged up as bycatch, mislabelled on supermarket shelves, and sold under generic terms like flake or cação to hide their identity. Now, research shows that when humans eat these animals, they’re also ingesting a cocktail of toxic metals that can damage brains, harm pregnancies, and trigger long-term health issues.
