Development Of Cryptic Worms Provides New Insights Into Molluscan Evolution
2013-10-18 12:20:59

University of Vienna There are still a lot of unanswered questions about mollusks, e.g. snails, slugs and mussels. The research group of Andreas Wanninger, Head of the Department of Integrative Zoology of the University of Vienna, took a detailed look at the development of cryptic worms. The larvae of the "wirenia argentea" hold a much more complex muscular architecture than their adults -- they remodel during their metamorphosis. That's a clue that the ancestors had a highly complex...

Experts Warn Texans Not To Touch Deadly Giant African Snails
2013-05-08 08:49:24

Lawrence LeBlond for redOrbit.com - Your Universe Online People in a Texas neighborhood may be looking for massive mollusks after a recent sighting of a giant African land snail in one Houston-area garden sparked interest. However, researchers are warning people to stay away from the supersized slugs as they are dangerous to touch because they have been known to carry meningitis. Anyone coming into contact with the creatures should wash their hands immediately. Autumn Smith-Herron,...

Idaho Governor "Butch" Otter has invited Naturopathix,Inc., maker of all-natural patented ZymaDerm for molluscum, to participate in the Governor's trade mission to Asia in April 2013. Meetings with distributors and retailers in Korea and Taiwan are anticipated to bring the painless treatment for molluscum developed by Briant Burke, MD, MS to these countries and open the door for distribution throughout Asia. Boise, ID (PRWEB) March 29, 2013 “We are delighted to have this opportunity...

How The Mollusc Got Its Teeth Revealed By Ancient Fossils
2012-08-22 15:06:06

The radula sounds like something from a horror movie — a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a "prototype" radula found in 500-million-year-old fossils studied by University of Toronto graduate student Martin Smith, shows that the earliest radula was not a flesh-rasping terror, but a tool for humbly scooping food from the muddy sea floor. The Cambrian...

Researchers Complete Mollusk Evolutionary Tree

Mollusks have been around for so long (at least 500 million years), are so prevalent on land and in water (from backyard gardens to the deep ocean), and are so valuable to people (clam chowder, oysters on the half shell) that one might assume scientists had learned everything about them. “Here´s this big, diverse group of animals, and we don´t know how they were related to each other,” said Casey Dunn, an evolutionary biologist at Brown University who specializes in...

Scientists from the United States, Norway, and Germany create a unique data set for the reconstruction of the phylogeny of molluscs Snails, mussels, squids — as different as they may look, they do have something in common: they all belong to the phylum Mollusca, also called molluscs. An international team of researchers headed by Kevin Kocot and Professor Ken Halanych, USA, with the participation of Johannes Gutenberg University Mainz (JGU), Germany, has carried out research into the...

Deep genomic analysis of Molluscsa shows there is more than 1 way to make a brain Seemingly simple animals such as the snail and squid have ransacked the genetic toolkit over the last half billion years to find different ways to build complex brains, nervous systems and shells, according to an international team of researchers, including a neuroscientist with the University of Florida Whitney Laboratory for Marine Bioscience. Using genomics and computational approaches, the scientists...

Two world experts in micro molluscs, Anselmo Peñas and Emilio Rolán, have made an unprecedented description in a scientific publication of a combined total of 209 snail species. Commissioned by the National Museum of Natural History in Paris, the study was unveiled in September in the French capital, and it covers the most new species from a single genus of any study to date. "Never have so many species from a single genus, nor even from a single family, been...

A study by researchers at the University of Toronto and the Royal Ontario Museum sheds new light on a previously unclassifiable 500 million-year-old squid-like carnivore known as Nectocaris pteryx. "We think that this extremely rare creature is an early ancestor of squids, octopuses, and other cephalopods", says Martin Smith of U of T's Department of Ecology and Evolutionary Biology (EEB) and the Department of Natural History at the ROM.  "This is significant because it means that...

A team of Catalan researchers has studied the changes in the make-up of animal populations following forest fires, and have concluded that malacological fauna are a good indicator of forest recovery. The conclusions of this study will help to ensure that post-fire forestry operations that do not harm these species of molluscs, which are sensitive to microclimatic conditions of the soil and vegetation structure. The researchers from the University of Barcelona (UB) and the Natural Areas...

Flat Tree Oyster, Isognomon alatus
2013-04-25 16:28:02

The Flat Tree Oyster, Isognomon alatus, is a species of bivalve mollusk belonging to the family Isognomonidae. It can be seen along the Atlantic coast of North America, ranging from southern Florida to Brazil and Bermuda. This oyster has two thin and irregularly shaped valves that are joined by a long straight hinge. The exterior is sculpted by a large number of rough, concentric rings with loose flakes and varies in color from a pale brownish olive to a purplish black. The nacre on the...

Noble Pen Shell, Pinna Nobilis
2013-04-25 16:25:11

The Noble Pen Shell, Pinna Nobilis, is a species of large saltwater clam, a marine bivalve mollusk belonging to the family Pinnidae. This bivalve shell can be as large as almost 3 feet in length, and the shape is somewhat variable. Like all pen shells, it is quite fragile. It attaches itself to rocks using a strong byssus made up of many silk like hairs. These are fibers that are secreted by the animal. Brilliant mother of pearl lines the inside of the shell. This species is native to...

Kelp Scallop, Leptopecten latiauratus
2013-04-16 20:25:12

Leptopecten latiauratus, the common name being the kelp scallop, is a small saltwater clam, a bivalve mollusk belonging to the family Pectinidae. It resides in water up to 850 feet deep. Similar to other scallops, it has many small primitive eyes around the rim of its mantle and escapes its predators by jet propulsion. The shell can be anywhere between 3 to 5 centimeters in size. It is mostly circular with two flat auricles or ears that extend off of the hinge. It usually has ridges that...

The Molluscum contagiosum virus, MCV, is a virus, in the poxvirus family, that causes the disease Molluscum contagiosum in humans. The virions have a complex structure that is consistent with the structure of the poxvirus family. Since the virus cannot routinely be cultured diagnosis is made on the clinical appearance. It can be confirmed by excisional biopsy. There are four types of MCV and MCV-2 is usually seen in adults and is often sexually transmitted. Photo Copyright and Credit
