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...

In the most computationally intensive phylogenetic analysis to date, an international research team led by Brown University has found the first evolutionary branching for bilateral animals. The researchers determined that the flatworm group Acoelomorpha is a product of the deepest split within the bilateral creatures "” multicelled organisms that, like humans, have symmetrical body forms. Results appear online in Proceedings of the Royal Society B. When it comes to understanding a...

The large group of segmented worms known as annelids, which includes earthworms, leeches and bristle worms, evolved millions of years ago and can be found in every corner of the world. Although annelids are one of the most abundant animal groups on the planet, scientists have struggled to understand how the different species of this biologically diverse group relate to each other in terms of their evolutionary history. Now a team of scientists from Yale University and Dartmouth College has...

Luminescent sea worms that eject glowing green blobs have been found off the Oregon coast at depths up to 11,000 feet, scientists said. Oregon is the hotbed for these guys, said co-discoverer Karen J. Osborn, a researcher at the Scripps Institution of Oceanography in La Jolla, Calif. Using a remotely operated submarine, Osborn and her team found the worms they dubbed Green Bombers between 5,900 and 11,000 feet below the surface, The Oregonian reported Friday. The worms, formally named Swima...

Researchers have discovered a new species of worm, dubbed the "green bomber." The worms, which live thousands of feet beneath the sea, can cast off green glowing body parts. In all, a total of seven new worm species were discovered by a research team led by Karen Osborn of the Scripps Institution of Oceanography at the University of California. The report on the worms will be in Friday's edition of the journal Science. "We found a whole new group of fairly large, extraordinary animals that we...

Working with researchers in China, biologists at UC San Diego have discovered how a Chinese drug effective in killing parasitic roundworms works. Their discovery of the drug's biological mechanism provides important new information about how to combat parasitic roundworms, which infect more than a billion people in tropical regions and are one of the leading causes of debilitation in underdeveloped countries. The researchers detail their findings in the current issue of the open-access...

The fossilized tracks of a giant marine worm that lived some 475 million years ago have been discovered byt the Spanish National Research Council (CSIC). Evidence of the worm, which was up to 3 feet in length, was found in the Cabaneros National Park in central Spain.  The region was once a seabed during the Lower Ordovician period, the Spanish researchers said. The CSIC said the worms dwelled within horizontal galleries 15 feet long and 6-8 inches in diameter under the seabed.  The...

 The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in this week's Current Biology.The scientists' report represents direct experimental evidence for the "Red Queen Hypothesis" of sex, which suggests sexual reproduction allows host species to avoid infection by their...

Scientists and researchers are scouring the Palouse region from eastern Washington into the Idaho panhandle in hopes of finding more of the dwindling giant Palouse earthworms, The Associated Press reported. The almost elusive worm is said to secrete a lily-like smell when handled, spit at predators, and live in burrows 15 feet deep. There have been only a handful of sightings. Even though there has been little research done on the Palouse worm, conservationists are asking the Obama...

The Sagalla caecilian (Boulengerula niedini) is a long, earthworm-like amphibian from the family Caeciliidae. The species is native to the tiny area of south-eastern Kenya called Sagalla Hill. The Sagalla caecilian has a slender body, perfect for burrowing. Its skin is extremely pigmented, lending it a brownish color with a pinkish-red hint, and white cross segments that give the appearance of grooves. They can grow up to 12 inches in length. Along with tough skin and a bony head, the...

The trumpet worm (Lagis koreni) is a species of polychaete worm that is classified within the Annelida phylum. It can be found in the waters around Europe including the North Sea, the Arctic Ocean, the Mediterranean Sea, the Atlantic Ocean, and the Adriatic Sea. This species is typically found submersed in sand in the neritic zone. The trumpet worm can reach an average length of about one inch and is typically light pink in color, with visible red veins and two pairs of red gills. This...

The nightcrawler (Lumbricus terrestris), also known as the lob worm or the common earthworm in Britain and the dew worm in Canada, is a species of earthworm that is classified within the Annelida phylum. It is native to Europe, but has been introduced into other areas around the world. Although the species is not as abundant as other worms in its range, it is a widely known species in gardens of temperate habitats, where it moves about on the surface of the soil. The nightcrawler can reach...

The Pompeii worm (Alvinella pompejana) is a species of polychaete worm, or bristle worm that is only found in the Pacific Ocean. It resides at hydrothermal vents, making it an extremophile, and was first discovered French marine biologists of the coat of the Galapagos Islands in the 1980s. It was described by Lucien Laubier and Daniel Desbruyeres as a deep-sea polychaete that could withstand extreme amounts of heat. The Pompeii worm can reach an average length of up to five inches and is...

Hydroides norvegica is a species of worm that is classified within the Annelida phylum. This species is known as a tube-forming worm, because its builds tube-shaped reefs in order to shelter itself. Its range includes the waters of the Persian Gulf, the Red Sea, the Mediterranean Sea, the Atlantic Ocean, and the Indian Ocean. It prefers to reside in coastal areas on shells, rock piles, and boats. A study conducted in Hawaii showed that this worm was one of four predominant species that made...
