Combinations of stress factors are stopping coral from growing in the Florida Keys according to the finding of new research led by University of North Florida Biology Professor Cliff Ross. It’s a clue into what is wiping out coral colonies worldwide.
First thing's first: coral may look like rocks, but coral are animals.
Ross explains, "They’re closely related to jellyfish. If you take a bunch of jellyfish and shrink them and stick them together, that’s a coral."
