A whale fall refers to the process of a dead whale sinking to the seafloor, where it can provide a source of food for deep-sea life. The remains of these whales can support a diverse range of species, with some areas accumulating large numbers of carcasses over time, potentially forming what has been described as a whale necropolis or graveyard. The exact locations and characteristics of these underwater graveyards vary, with discoveries reported in areas such as the Diamantina Zone and the Indian Ocean.
