  • These were mysid shrimp, which were often used in tests to see whether polluted water was harming marine life. For years, Ciba-Geigy had refused to conduct those mysid tests, preferring instead to test its effluent on a much hardier animal, the sheepshead minnow. (The company's critics would later call the minnow the "cockroach of the sea" for its ability to survive even in highly toxic environments.
