Insidious coral killer invading Palmyra Atoll reef

A new study reveals that a corallimorph species is outcompeting stony corals in Palmyra Atoll's reefs, leading to a significant shift in ecosystem dominance. The invading species, closely related to one from Okinawa, Japan, can rapidly monopolize the seafloor and reach 100% cover, posing concerns about irrevocability of this phase shift.
