California's sea otters were once hunted to near-extinction, but now, thanks to recovery programs, they are bouncing back. It turns out that's not just good news for the otters, but also for their ecosystem.

Here to explain is marine ecologist Brent Hughes, who's leading research on this at UC Santa Cruz.
