480-million-year-old parasite still plagues today's shellfish
A new study has unexpectedly discovered that a common parasite of modern oysters actually started infecting bivalves hundreds of millions of years before the dinosaurs went extinct.
Mollusks are a highly diverse phylum (Mollusca) of invertebrate animals that constitute a major topic in zoology and evolutionary biology, encompassing classes such as Gastropoda, Bivalvia, and Cephalopoda. They are characterized by a soft, unsegmented body typically organized into head, visceral mass, and muscular foot, with many species secreting a calcareous shell from a specialized mantle. Research on mollusks addresses themes including biomineralization, neurobiology (especially in cephalopods), developmental and evolutionary genetics, functional morphology of feeding and locomotion, ecological roles in marine and freshwater systems, and their importance as model organisms in environmental toxicology and climate-change impact studies.
