Lacking protective shells, they have evolved potent chemical defences and many display brilliant warning colouration. Recent molecular studies indicate that opisthobranchs are not monophyletic &ndash; that is, they do not share an exclusive common ancestral species. Thus a challenge remains to precisely reconstruct the evolution of these and related groups, while at the same time exploring their species diversity.&lt;/p&gt;&lt;p&gt;Dr Terrence Gosliner of the California Academy of Sciences and colleagues reviewed Indo-Pacific species of the opisthobranch family Aglajidae in 2008, recognising 23 species from the region and pointing to what were probably 16 additional undescribed species. Ten more  have been described in the past three years including six new tropical species by Gosliner. Among these is &lt;em&gt;Chelidonura mandroroa&lt;/em&gt;, which has a black body marked by psychedelic yellow-outlined orange patches. The specific epithet mandroroa is appropriately derived from the Malagasy word meaning to hallucinate.&lt;/p&gt;&lt;p&gt;&lt;em&gt;C mandroroa&lt;/em&gt; has been found off the coasts of Japan, Taiwan, the Philippines, Indonesia, Madagascar and Kenya, an impressively broad distribution for a newly recognised species. It was discovered crawling under or on coral rubble in shallow reefs at 8m to 13m depth. The recent speed of discovery of species suggests that many additional ones await discovery.&lt;/p&gt;&lt;p&gt;&lt;em&gt;Quentin Wheeler is director of the International Institute for Species Exploration, Arizona State University&lt;/em&gt;&lt;/p&gt;&lt;div class=&quot;related&quot; style=&quot;float: left; margin-right: 10px; margin-bottom: 10px;&quot;&gt;&lt;ul&gt;&lt;li&gt;&lt;a href=&quot;http://www.guardian.co.uk/science/zoology&quot;&gt;Zoology&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href=&quot;http://www.guardian.co.uk/world/animals&quot;&gt;Animals&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href=&quot;http://www.guardian.co.uk/environment/wildlife&quot;&gt;Wildlife&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;/div&gt;&lt;div class=&quot;author&quot;&gt;&lt;a href=&quot;http://www.guardian.co.uk/profile/quentin-wheeler&quot;&gt;Quentin Wheeler&lt;/a&gt;&lt;/div&gt;&lt;br/&gt;&lt;div class=&quot;terms&quot;&gt;&lt;a href=&quot;http://www.guardian.co.uk&quot;&gt;guardian.co.uk&lt;/a&gt; &amp;copy; 2011 Guardian News and Media Limited or its affiliated companies.
