Miocene whale-fall from California demonstrates that cetacean size did not determine the evolution of modern whale-fall communities.
Whale-fall communities support a deep-sea invertebrate assemblage that subsists entirely on the decaying carcasses of large cetaceans. The oldest whale-falls are Late Eocene in age, but these early whale-falls differ in faunal content and host cetacean size from Neogene and Recent whale-falls. Vesicomyid bivalves, for example, are major components of the sulphophilic stage in Miocene and Recent...

متن کاملNot whale-fall specialists, Osedax worms also consume fishbones.
Marine annelid worms of the genus Osedax exploit sunken vertebrate bones for food. To date, the named species occur on whale or other mammalian bones, and it is argued that Osedax is a whale-fall specialist. To assess whether extant Osedax species could obtain nutrition from non-mammalian resources, we deployed teleost bones and calcified shark cartilage at approximately 1000 m depth for five m...
متن کاملMolluscs from a shallow-water whale-fall in the North Atlantic
We conducted a species-level study of molluscs associated with a 5 m long 17 carcass of a minke whale at a depth of 125 m in the Kosterfjord (North Sea, Sweden). The 18 whale fall community was quantitatively compared with the community commonly living in 19 the surrounding soft-bottom sediments. Five years after the deployment of the dead whale at 20 the sea floor, the sediments around the wha...
متن کاملDeep-sea whale fall fauna from the Atlantic resembles that of the Pacific Ocean.
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...
