<p>Marine snails: shape changes during development and evolution</p>=0D=0A=
<p>Gastropod molluscs (&ldquo;snails&rdquo;) have evolved feeding structures to utilize a diversity of food sources. Some gastropods have retained the ancestral pattern of grazing on algae, while others have become suspension feeders, sediment feeders, or predators. Remarkably, however, this diversity has occurred despite the fact that most gastropods begin life as a free-swimming, planktonic larva that must feed on microalgae. Dr. Louise Page, Department of Biology, UVic will explore three questions: 1) How is the larval feeding system of gastropods transformed into the radically different feeding systems of juvenile &amp; adult gastropods, 2) How is this transformation accomplished so quickly, even in predatory gastropods with highly complex feeding systems, and 3) Has the developmental system contributed to the rapid evolutionary diversification of predatory gastropod feeding systems.</p>=0D=0A=
<p>We meet at 7:30 p.m. in Room 159 of the Fraser Building, University of Victoria. Everyone is welcome.</p>=0D=0A=
