A whale fall is a whale carcass that has fallen to the ocean floor. Whale falls were first observed in the 1980s, with the advent of deep-sea robotic exploration.
When a whale dies in shallow water, its carcass is typically devoured by scavengers over a relatively short period—within 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. Some of the organisms that have been observed at whale falls are giant isopods, squat lobsters, bristleworms, prawns, shrimp, lobsters, hagfish, Osedax (bone-eating worms), crabs, sea cucumbers, octopuses, clams, and even deep-sea sleeper sharks. Whale falls are often inhabited by large colonies of tube worms. Over 30 previously unknown species have been discovered at whale falls.

Famous quotes containing the words whale and/or fall:
“And one rose in a tent of sea and gave
A darkening shudder; water fell away;
The whale stood shining, and then sank in spray.”
