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...

Chromosomal Evolution Advancement In Sea Cradles

Pensoft Publishers The study of chromosome changes arisen during species evolution is a current and intriguing topic that evolutionary biology proposes. However, in several groups (for example, mollusks), and chitons in particular, chromosome studies are scarce, with a few species investigated and analyses performed mostly with simple methods. Only 2,5% of about 900 living species of chitons have been so far karyologically investigated, all of them in the same order (Chitonida). The...

multiplacophoran reconstruction
2012-09-20 10:30:45

Brett Smith for redOrbit.com - Your Universe Online Using computer animation, CT scanning and 3-D printing technology, a team led by University of Texas at Austin paleontologist Jakob Vinther has reconstructed an ancient mollusk that inhabited the waters around modern day Ohio about 390 million years ago. Until now, only a few partial fossils of the creature, known as a multiplacophoran, existed and the new model allows paleontologists to study the physiology of the specimen in greater...

Using eyes made of a calcium carbonate crystal, a simple mollusk may have evolved enough vision to spot potential predators, scientists say. The three-inch-long mollusks, called chitons, have hundreds of eye-like structures with lenses made of aragonite, a type of rock. It's the first time scientists have found an animal that makes eye lenses from aragonite and not the rock's close cousin, calcite. "It's surprising how these creatures make their eyes from rocks," said Duke biologist...
