Some species have an <a href="/wiki/Operculum" title="Operculum">operculum</a>, a lid or trapdoor to close the shell. In some, the slugs, the shell is absent, and the body is streamlined. The best-known gastropods are land slugs and snails, but more than half of all species live in a <a href="/wiki/Ocean" title="Ocean">marine</a> environment. Marine gastropods include <a href="/wiki/Herbivore" title="Herbivore">herbivores</a>, <a href="/wiki/Detritus" title="Detritus">detritus</a> feeders, <a href="/wiki/Carnivore" title="Carnivore">carnivores</a> and a few <a href="/wiki/Cilia" title="Cilia">ciliary</a> feeders, in which the <a href="/wiki/Radula" title="Radula">radula</a> is reduced or absent. The radula is usually adapted to the food that a species eats. </p><p>The simplest gastropods are the <a href="/wiki/Limpet" title="Limpet">limpets</a> and <a href="/wiki/Abalone" title="Abalone">abalones</a>, both herbivores that use their hard radulas to rasp at <a href="/wiki/Seaweed" title="Seaweed">seaweeds</a> on rocks. Many marine gastropods are <a href="/wiki/Burrow" title="Burrow">burrowers</a> and have siphons or tubes that extend from the <a href="/wiki/Mantle_(mollusc)" title="Mantle (mollusc)">mantle</a> and sometimes the shell. These act as snorkels, enabling the animal to continue to draw in a water current containing <a href="/wiki/Oxygen" title="Oxygen">oxygen</a> and food into their bodies. The siphons are also used to detect prey from a distance. These gastropods breathe with <a href="/wiki/Gill" title="Gill">gills</a>. Some freshwater species and almost all terrestric species have developed <a href="/wiki/Lung" title="Lung">lungs</a>. </p><p>Gastropods from several different families are called <a href="/wiki/Sea_slug" title="Sea slug">sea slugs</a>. They are often flamboyantly coloured. This may be either as a <a href="/wiki/Warning_colouration" title="Warning colouration">warning</a> if they are <a href="/wiki/Poison" title="Poison">poisonous</a> or to <a href="/wiki/Camouflage" title="Camouflage">camouflage</a> them on the <a href="/wiki/Coral" title="Coral">corals</a> and <a href="/wiki/Seaweed" title="Seaweed">seaweeds</a> where many of them live. Their gills are often <a href="/wiki/Feather" title="Feather">feathery</a> plumes on their backs. This is what gives the name to the <a href="/wiki/Nudibranch" title="Nudibranch">nudibranchs</a>. Nudibranchs with smooth or warty backs have no visible gill mechanisms and respiration may take place directly through the skin. A few of the sea slugs are herbivores and some are carnivores. Many have distinct dietary preferences and regularly occur in association with certain species. </p> <div class="mw-heading mw-heading2"><h2 id="Classification">Classification</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gastropoda&veaction=edit&section=2" title="Change section: Classification" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Gastropoda&action=edit&section=2" title="Edit section's source code: Classification"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/Taxonomy" title="Taxonomy">taxonomy</a> of the Gastropoda is under constant revision: two major revisions have been published in the last twenty years.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> There will certainly be other revisions using the <a href="/wiki/Data" title="Data">data</a> from <a href="/wiki/DNA" title="DNA">DNA</a> sequencing.
