Predator Fish Help Coral Reefs Rebound, Study Shows

The return of a top predator in a Bahamas marine reserve is proving unexpectedly beneficial to coral reefs there, according to a new study.

The finding is a relief to scientists, who were concerned that the reserve’s population of predatory Nassau grouper would swell at the expense of the already vulnerable reefs, which are quickly disappearing due to disease, hurricanes, and warming oceans.
