    According to AIMS’s Long Term Monitoring Program, most are a weedy genus of fast-growing corals known as Acropora. These include species like staghorn, elkhorn, and tabletop corals, which, though prolific, are easily broken up by cyclones—weather events that are expected to become more frequent and intense. Worse, they’re a favorite food for COTs, a species that continues to grow more comfortable on the Great Barrier Reef as surrounding waters warm.

    Instead of a diverse, old-growth forest, [the reef] may now be like a monoculture of planted pulp trees,’” says Hughen. With less diversity of corals on the Great Barrier, he adds, there will also be fewer structures that house and feed various species of fish and marine invertebrates. Some, like the parrotfish—a valuable grazer that keeps algae from smothering corals—have already suffered decline in the northern third of the reef following mass bleaching events that began in 2016.
