Whale fall is the term used for a whale carcass that has fallen to the ocean floor. When a whale dies in shallow water, its carcass is typically devoured by scavengers over a relatively short period of timewithin several months. However, in deeper water (depths of 2,000 m/6,600 ft or greater), fewer scavenger species exist, and the carcass can provide sustenance for a complex localized ecosystem over periods of decades. Over 30 previously unknown species have been discovered at whale falls.
