Biggest Animals in Ocean More Likely to Go Extinct

What happens when you remove all the biggest animals from the ocean? Stick around for the next few thousand years and you might find out. A new study finds that in our modern era, large marine animals are significantly more likely to go extinct than small ones. It’s a disturbing pattern that has the potential to wipe out many of the top predators in our oceans, and the researchers say it has never been seen before in the history of our planet. After analyzing marine fossil records that go as far back as 445 million years, the authors report that in the past extinction rates have been fairly egalitarian, affecting ocean animals of all sizes equally.
