Ocean Warming Has Been Shrinking Marine Animals for 450 Million Years, Massive Study Reveals

Ocean warming has been shrinking marine animals for 450 million years, massive study reveals

Science News: Marine animals do not just struggle when ocean temperatures spike, they actually shrink, and a massive new study shows this pattern has been repeating.

Analysis of nearly 9,000 body size changes spanning 450 million years finds warming events caused about twice the reduction in marine animal body size seen during other environmental crises, suggesting smaller marine animals could become increasingly common as the climate warms.
