Scientists will unleash an army of crabs to help save Florida's dying reef

With giant pincers and rough, spider-like legs, Caribbean king crabs don’t look like your typical heroes. Yet these crustaceans may be key to solving one of the world’s most pressing environmental problems: the decline of coral reefs.

In recent decades, warming seas, diseases, and other threats have wiped out half of the world’s corals and 90 percent of those in Florida. And this past summer, the problem accelerated. A devastating heat wave struck the Caribbean, pushing the reef in the Florida Keys — the largest in the continental US — closer to the brink of collapse.

The decline of coral reefs is an enormous problem for wildlife and human communities. Reefs not only provide habitat for as much as a quarter of all marine life, including commercial fish, but they also help safeguard coastal communities during severe storms. Simply put, we need coral reefs.

Coral reefs, meanwhile, need crabs.

Lucky for them, help is on the way. Scientists are in the process of building a crab army — hundreds of thousands of crustaceans strong — that they’ll unleash on Florida’s reefs, giving this ailing ecosystem a tool to fight back.

This is beyond cool! Go forth and multiply, little guys!

1. They also have certain kinds of fish that eat those starfish that seem to prefer munching on corals.

I imagine that they are numerous species that eat starfish (the kind that munch on corals).
