Shipwreck damages pristine coral reef via destructive organism

Nestled within the new Pacific Remote Islands Marine Monument lies Palmyra Atoll, one of the last pristine coral reefs left on the planet some 960 nautical miles south of Hawaii. Or near pristine. In 1991, a 100-foot longline fishing ship—the "Hui Feng No. 1"—foundered on the reef under mysterious circumstances. In the wake of that shipwreck, a destructive species of corallimorpharian—a kind of half-coral, half-anemone sea creature—began to take over the reef.

In the intervening years, the species has spread to cover nearly two square kilometers of the reef, though its density declines the further from the shipwreck you go, ultimately disappearing entirely in more undisturbed areas. Near the shipwreck, however, this Rhodactis howesii has overgrown the underlying reef, killing its coral cousins. It also crops up near buoys in the area. "They are very aggressive … and use specialized anatomic structures called 'sweeper tentacles' that have stinging cells," says wildlife veterinarian Thierry Work of the U.S. Geological Survey, who has studied the problem. "These tentacles are used to kill adjacent organisms, like corals, so as to capture real estate."
