Larger marine animals will be at higher risk of extinction, and humans are to blame, the Stanford study suggests.
In today's oceans, larger marine animals are more likely to go extinct than smaller creatures. It's a pattern that is unprecedented in the history of life on Earth, and one that is likely driven by human fishing, according to Jonathan Payne, a paleontologist at Stanford's School of Earth, Energy and Environmental Sciences.
"This is probably because people are fishing for larger species for consumption in the first place," he explained.
The analysis carried out by the scientists has shown that increasing an animal's body weight by ten times would increase its risk of extinction by 13 times or more.
During the last 440 million years on Earth there have been five mass extinctions (not counting the Eocene-Oligocene), and during these periods the number of species was reduced by 90%.
