Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

The parrotfish is like a house cleaner who does a great job of keeping things tidy, but sometimes breaks a glass. You want to keep them around, but you just wish they’d be a little less destructive.
For the parrotfish, the “houses” are coral reefs. They clean tiny organisms off the coral, keeping the coral healthy. But they also chip off pieces of the coral. If they chip away too much, they can damage the coral.
Parrotfish have strong teeth. They grind up the coral they chip off, then poop it out as grains that can wash up on the beach as white sand.
The scraping can scar the hard coral—the “skeleton” created by the living organisms inside, known as polyps. In many cases, the coral heals as new polyps move in. But in others, the coral can collapse. And if too many corals are destroyed, an entire reef can suffer.
Researchers spent a decade studying the coral-parrotfish relationship in four regions of the Caribbean Sea. They looked at individual corals, complete reefs, and wider areas that encompass many reefs. They also studied the parrotfish populations.
They found that more parrotfish generally meant more damage to the corals—but not always. Parrotfish prefer some species of corals over others. So in regions where those species weren’t as common—or where there was less variety of coral species—the damage was less severe.
The results may help managers control the parrotfish catch—perhaps improving the health of coral reefs across the Caribbean.
