Brooding Marine Worm Found In Antarctica
2013-11-27 16:10:40

University of Barcelona Brooding is a usual behavior in animals. However, to observe it in a marine worm is exceptional and, more surprisingly, it guards eggs from external threats. The scientific finding, published recently in the journal Polar Biology, was developed by researchers Conxita Àvila and Sergio Taboada, from the Department of Animal Biology of the University of Barcelona (UB) and members of the Institute of Research in Biodiversity (IRBio); Juan Junoy, from the University of...

Zombie Worms And Shipwrecks
2013-08-14 10:30:33

Brett Smith for redOrbit.com - Your Universe Online Zombie worms are coming for your bones – but probably only if they end up at the bottom of Antarctic waters. A new report in the Proceedings of the Royal Society B suggested that if a wooden ship and its crew sank in the Southern Ocean that surrounds Antarctica, any evidence of the crew would decompose long before the ship itself. That's because so-called "zombie worms" - including two newly discovered species - living at the bottom...

Bone-melting substance drills opening for worms to access nutrients within dead whales Only within the past 12 years have marine biologists come to learn about the eye-opening characteristics of mystifying sea worms that live and thrive on the bones of whale carcasses. With each new study, scientists have developed a better grasp on the biology of Osedax, a genus of mouthless and gutless "bone worms" that make a living on skeletons lying on the seafloor. In the latest finding,...

Minke Whale Skeleton Found At Bottom Of Antarctic Ocean

Lee Rannals for redOrbit.com — Your Universe Online Marine biologists reported in the journal Deep-Sea Research II: Topical Studies in Oceanography they have discovered a whale skeleton sitting on the ocean floor near Antarctica for the first time. Researchers said they made the discovery nearly a mile below the surface of the ocean in an undersea crater, offering some new insights into life in the sea depths. Until now, whale carcasses have never been studied in the Antarctic...

Recently discovered worm with bone-eating lifestyle not exclusive to whale carcasses A new study led by a scientist at Scripps Institution of Oceanography at UC San Diego is painting a more complete picture of an extraordinary sea worm that makes its living in the depths of the ocean on the bones of dead animals. Discovered fewer than 10 years ago off Monterey, Calif., but since identified in other oceans, the flower-like marine "boneworms," or Osedax, have been documented mainly living upon...

Dead whales that sink down to the seafloor provide a feast for deep-sea animals that can last for years. Previous research suggested that such "whale falls" were homes for unique animals that lived nowhere else. However, after sinking five whale carcasses in Monterey Canyon, researchers from the Monterey Bay Aquarium Research Institute (MBARI) found that most of the animals at these sites were not unique to whale falls, but were common in other deep-sea environments as well. Nonetheless, the...

An international team of scientists led by the paleontologist Steffen Kiel at the University of Kiel, Germany, found the first fossil boreholes of the worm Osedax that consumes whale bones on the deep-sea floor. They conclude that "boneworms" are at least 30 Million years old. This result was published in the current issue of the scientific journal Proceedings of the National Academy of Sciences of the USA (PNAS, April 19, 2010). Six years ago Osedax was first described based on specimens...

It sounds like a classic horror story"”eyeless, mouthless worms lurk in the dark, settling onto dead animals and sending out green "roots" to devour their bones. In fact, such worms do exist in the deep sea. They were first discovered in 2002 by researchers at the Monterey Bay Aquarium Research Institute (MBARI), who were using a robot submarine to explore Monterey Canyon. But that wasn't the end of the story. After "planting" several dead whales on the seafloor, a team of biologists...

The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected. Californian researchers investigating the genetic history of Osedax worms have found that up to twelve further distinct evolutionary lineages exist beyond the five species already described. The new findings about these beautiful sea creatures with unusual sexual and...

An unusual relationship between bacteria and a newly discovered group of marine worms is the only known partnership (or symbiosis) which uses sunken marine mammals as its sole source of nutrition. In the September issue of Environmental Microbiology, Dr Shana Goffredi and her colleagues reveal this unique partnership between bacteria and the Osedax (bone-devouring) group of marine worms. Symbiosis, or the living together of different organisms, allows some species to live in otherwise...
