Certain episodes of mass fish mortality in coastal waters off the eastern United States have been ascribed to a planktonic organism called Pfiesteria. There are now fresh clues to how these fish are killed.

In James Powlik's novel Sea Change1, a colony of mutant cells called Pfiesteria grows into a carpet-like monster stretching over several square miles of the Strait of Juan de Fuca, a body of water separating the west coast of the United States and Canada. Its slow movement south threatens the residents of Seattle with a nightmarish fate — death following inhalation or ingestion of a toxin produced by the microbes.
