Common minke whale sharks have been found scavenging the blubber thrown overboard during Norwegian minke whaling operations off Svalbard. Great white sharks and blue sharks have also been observed feeding on a minke whale carcass off California. A new species of siboglinid annelid worm, "Osedax mucofloris", was discovered on the carcass of a 5.3 m (17.4 ft) female minke whale experimentally placed at a depth of 125 m (410 ft) in the North Sea.
