Samantha Leigh, a graduate student and ecologist at the University of California, Irvine, who led the new research, wasn’t satisfied. She wanted to find out if the sharks could actually digest the grass. So, she put captive bonnethead sharks on a mostly vegetarian diet of seagrass and squid for three weeks. She tagged the seagrass with a marker she could track as the fish consumed the plant material, digested and excreted it.

Although she started the project suspecting she’d be proving the assumptions right, Leigh found instead that the sharks digested about half the seagrass they consumed. “That’s on par with herbivorous fish,” said Leigh. It’s also better than pandas are able to digest bamboo.
