The Natural History Museum in London said on Friday that it is seeking the public's advice in naming a new species of sea-dwelling worm. The unnamed worms are known as annelids and the species spends its time about 6,500 feet below the surface of the sea in Antarctic. "Our goal is to show that taxonomy, the scientific discipline of naming new species, is interesting, fun and crucial to the advancement of science," zoologist at the National History Museum, Adrian Glover, said in a press...

Invasion Of The Earthworms
2011-09-12 09:22:21

  Non-native earthworms are damaging hardwood forests [ View the Science Nation Video ] Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they're an excellent addition to a compost pile. But what a lot of people don't know is many earthworms are actually invasive species. "The western Great Lakes region, which is the area we're focused on, has no native earthworms," says ecologist Cindy Hale, a research associate...

Study shows humans to blame for spread of non-native species It is widely acknowledged that human beings are largely responsible for the widespread alteration of ecosystems on the planet. A recent study by Dara Seidl and Peter Klepeis of Colgate University in New York traces the ways in which humans are the principal agents of dispersal of exotic earthworms in the forests of Northern America. Their findings, published online in Springer's journal Human Ecology, suggest that humans spread...

Flatworms provide new insight into organ regeneration and the evolution of mammalian kidneys Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea"”famous for its capacity to regrow complete animals from minuscule flecks of tissue"”as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant...

Polychaete worms have populated the oceans for millions of years. Today they are the focus of study on cryptic species, which shows that apparently identical animals may be entirely different species. Researchers at the University of Gothenburg, Sweden, have now found new worm species in the Kattegat and Skagerrak. Polychaetes belong to a group of segmented worms that display enormous diversity. It turns out that there may be significantly more of these worms than researchers had imagined....

Scientists have discovered two living specimens of the giant Palouse earthworm near Spokane, Washington. One adult and one juvenile were found by University of Idaho soil science student Shan Xu and research support scientist Karl Umiker on March 27, according to a Tuesday press release posted at the university's website. Furthermore, they also discovered three Palouse cocoons, two of which have already hatched while under laboratory observation. According to Nicholas K. Geranios of the...

Scientists have unearthed the remains of one of the world's rarest fossils - in downtown Ottawa. The 450 million year old fossil preserves the complete skeleton of a plumulitid machaeridian, one of only 8 such specimens known. Plumulitids were annelid worms - the group including earthworms, bristleworms and leeches, today found everywhere from the deepest sea to the soil in your yard - and although plumulitids were small they reveal important evidence of how this major group of organisms...

As the use of leeches in a variety of medical therapies is beginning to increase in popularity, an institution in Russia is hoping to cash in. The International Medical Leech Center in Udelnaya refers to itself as the world's largest leech-growing facility. Many experts and leading institutions have begun approving the use of leeches for medical procedures. Earlier this year, the American Journal of Nursing confirmed a resurgence of leech therapy, primarily among patients who underwent...

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...

Waste from the textiles industry could with the assistance of earthworms and some animal manure become a rich compost for agriculture, according to a report in the International Journal of Environment and Pollution.Most gardeners will tell you the earthworm is their best friend as it aerates the soil and helps break down compostable materials so releasing nutrients for improved plant growth. One particular species of earthworm, known as Eisenia foetida, thrives in rotting vegetation, compost,...

The Christmas Tree Worm (Spirobranchus giganteus) is a species of small, tube-building polychaete worm in the Serpulidae family. It is widely distributed throughout the world’s tropical oceans, occurring abundantly from the Caribbean to the Indo-Pacific. The worm’s common and scientific nomenclature refers to the two chromatically hued spiral structures, most prominently seen by divers. These multicolored spiral structures are actually part of the worm’s highly derived respiratory...

Paralvinella sulfincola
2014-01-12 00:00:00

Paralvinella sulfincola is a species of worm in the Alvinellidae family. It lives among undersea hot-water vents, thriving in the hottest of waters, at temperatures that would kill most animals. This characteristic makes it an extremophile or hyperthermophile. Having the unique ability to withstand extremely hot water from hydrothermal openings enables this stalk-like worm to feed on bacteria that other animals cannot reach. It is difficult to know exactly what temperatures this species...

The Giant Feather Duster Worm (Eudistylia polymorpha) is a species of marine polychaete worm of the Sabellidae family. Its range extends along the western coast of North America, from Alaska to California. It is most commonly found in the intertidal zone in tide pools and in the neritic (coastal) zone at depths up to 1,375 feet. It is often found in groups along rocks, reefs, pilings, wharves and marinas. Its common name comes from the crown of tentacles extended when the animal is under...

Phytobdella catenifera
2014-01-12 00:00:00

Phytobdella catenifera is a species of leech found in Peninsular Malaysia. The specimen was first collected from a brown tortoise in 1935. One record of the species was found in Gabai Falls, Selangor and has rarely been seen since. One reason is because it only attaches to reptiles and is of no threat to humans. This 2-inch-long terrestrial leech was named by Professor John Percy Moore due to the striking chain-striped pattern on the creature’s back. Recent studies on leech genetics...
