Dead whale feeds deep-sea animals, videos


This 16 October 2019 video says about itself:

Whale Fall Actively Devoured by Scavengers at Davidson Seamount| Nautilus Live

During the final dive of this year’s Nautilus expedition season, our team discovered a whale fall while exploring Davidson Seamount off central California’s coast with researchers from Monterey Bay National Marine Sanctuary. The skeletal remains of the whale lying on its back are estimated to be 4-5 meters long. The team is working to identify the species, but it is confirmed to be a baleen whale as indicated by baleen remaining along the whale’s jawbones.

While evidence of whale falls have been observed to remain on the seafloor for several years, this appears to be a relatively recent fall with baleen, blubber, and some internal organs remaining. The site also exhibits an interesting mid-stage of ecological succession, as both large scavengers like eelpouts are still stripping the skeleton of blubber, and bone-eating Osedax worms are starting to consume lipids (fats) from the bones. Other organisms seen onsite include crabs, grenadier, polychaetes, and deep-sea octopus.

This 17 October 2019 video is the sequel. It says about itself:

The banquet continues! Yesterday we made a surprise baleen whale fall discovery that viewers around the globe watched alongside the Nautilus team in Monterey Bay National Marine Sanctuary. Get a close up look at some of the scavenging diners including eelpouts, octopus, and polychaete worms–like the bone-eating Osedax worms that carpet the whale’s bones in a red fringe.
