The Crown-Of-Thorns Starfish may not look like much, but their impact is inarguable. They feed heavily on corals essential for building reefs, the marine equivalent of a metropolis. When these starfish have a boom in their population, the result is a significant loss of live coral. The damage has a higher impact on the reef’s health and resilience than bleaching and disease combined. The incredible diversity of other species dependent on that coral face sharp declines in turn. And it’s not just wild lives that are affected. These reefs act as natural barriers or shields protecting coastal cities. Without those barriers, coastal plants and beaches are at risk. Plus, reef-dependent industries face significant losses. Now, scientists think they may have found a solution---a Trojan Horse.
