Great Northern Tilefish : The Great Dying of 1882
The Great Northern Tilefish (Lopholatilus chamaeleonticeps) is a big, beautiful fish from the western Atlantic. It's one of those rare animals that is capable of reshaping its physical environment over vast areas. But it's also interesting for a rather unique reason. It was discovered, entirely accidentally, in 1879 and within 3 years of that discovery, something entirely unexpected and dramatic happened that involved millions upon millions of dead fish.
