2. What is a whale fall? - National Ocean Service
When whales die and sink, their carcasses — known as whale falls — provide a bounty of nutrients for deepwater creatures.
The oceans' depths are supplied by nutrients falling down from the surface waters. When whales die and sink, the whale carcasses, or whale falls, provide a sudden, concentrated food source and a bonanza for organisms in the deep sea. Different stages in the decomposition of the whale carcass support a succession of marine biological communities. Scavengers consume the soft tissue in a matter of months. Organic fragments, or detritus, enrich the sediments nearby for over a year. Importantly, the skeleton supports rich communities for years to decades, both as a hard substrate, or the base, for invertebrate colonization and as a source of sulfides from the decay of organic compounds of whalebones. Microbes live off of the energy released from these chemical reactions, particularly and form the basis of ecosystems for as long as the food source lasts. At deep sea levels this forms a new food web and provides energy to support single- and multi-cell organisms and sponges, thus adding to the oceans food chain.
3. Review of the Impact of Whale Fall on Biodiversity in Deep-Sea Ecosystems

“Whale Fall” is a collective term for the whale carcass, the process of dead whale fall, and the formed deep-sea ecosystem. The whale fall process produces a lot of unstable organic matter that has a significant impact on deep-sea ecosystems. Scientists speculate that organic matter input is the source of energy and material for organisms in deep-sea ecosystems. In the seafloor of the North Pacific, whale fall supports the survival of at least 12,490 organisms of 43 species, contributing to the prosperity of deep-sea life. Due to the specificity of the time and space of the formation of whale fall, there are few studies on whale fall and its impact on the deep-sea ecosystem. This article summarizes and analyses the current research status on the distribution of whale fall and its impact on the deep-sea ecosystem at home and abroad. The results show that the current distribution of whale fall is mainly concentrated in the Pacific and Atlantic regions, and the research on the impact of whale fall on deep-sea ecosystems focuses on the formation process, degradation rate and impact on deep-sea biological systems. This article has some significance to the understanding of biodiversity and ecosystem succession in the deep-sea “desert area.”

Whale carcasses create remarkable habitats in the deep-sea by producing concentrated sources of organic matter for a food-deprived biota as well as places of evolutionary novelty and biodiversity. Although many of the faunal patterns on whale falls have already been described, the biogeography of these communities is still poorly known especially from basins other than the NE Pacific Ocean. The present work describes the community composition of the deepest natural whale carcass described to date found at 4204 m depth on Southwest Atlantic Ocean with manned submersible Shinkai 6500. This is the first record of a natural whale fall in the deep Atlantic Ocean. The skeleton belonged to an Antarctic Minke whale composed of only nine caudal vertebrae, whose degradation state suggests it was on the bottom for 5–10 years. The fauna consisted mainly of galatheid crabs, a new species of the snail Rubyspira and polychaete worms, including a new Osedax species. Most of the 41 species found in the carcass are new to science, with several genera shared with NE Pacific whale falls and vent and seep ecosystems. This similarity suggests the whale-fall fauna is widespread and has dispersed in a stepping stone fashion, deeply influencing its evolutionary history.
