On the Arctic sea floor lie hungry predators that can eat polar bears.
The voracious carnivores are seastars, better known as starfish, and a new study by a national research group says they tie with polar bears as the top predators of the Arctic marine ecosystem.
Seastars within the Pterasteridae family sat at the top, with the study dubbing them "the benthic equivalent to polar bears." "You have a whole food web, including primary predators, herbivores and many carnivores. So it's way more complex than what we thought," Amiraux said.
