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.
From a fishing trawler in the Adriatic, Italian scientists gently release thousands of tiny octopuses in the hope of fighting an invasive crab species that has devastated local fisheries.

The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core ...
