<ul>
<li><span>The following organisms are all <b>invertebrates</b>: worms, <span lang="en">medusas</span>, molluscs, and arthropods (crustaceans, spiders, and insects)</span></li>
<li>A clam is a <b>mollusc</b>, a crab is a <b>crustacean</b>, and a dragonfly is an <b>insect</b>. Crustaceans and insects belong to the group of arthropods.</li>
<li><span>Water-dwelling invertebrates get their oxygen by either:</span>
<ul>
<li><span>using specialized organs called <b>gills</b> to filter oxygen from water.</span></li>
<li><span>occasionally coming up to the surface to breathe oxygen from the atmosphere.</span></li>
</ul>
</li>
<li><span>Many species of insects undergo a process of <b>metamorphosis</b>. A complete metamorphosis consists of the egg, larval, pupal, and adult stages. An incomplete metamorphosis lacks a pupal stage. </span></li>
