Abstract: When whales die and sink to the sea-floor, they provide a sudden, enormous food supply to organisms in the vicinity. At first, larger mobile scavengers remove the flesh, but also when only the bones remain, the whale-fall can still sustain macrofauna communities for several years. Some organisms have adapted so well to this kind of food source that they would have problems living elsewhere, e.g. species within the polychaete genus Osedax which have developed a root system which can bore into the... more
