This study documents the overall diet of the genus &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;Campylomormyrus&lt;/em&gt;&lt;/jats&gt; and examines the hypothesis that the &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;Campylomormyrus&lt;/em&gt;&lt;/jats&gt; radiation is caused by adaptation to different food sources. We performed diet assessment of five sympatric &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;Campylomormyrus&lt;/em&gt;&lt;/jats&gt; species (&lt;jats italic=&quot;&quot;&gt;&lt;em&gt;C. alces&lt;/em&gt;&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;C. compressirostris&lt;/em&gt;&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;C. curvirostris&lt;/em&gt;&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;C. tshokwe&lt;/em&gt;&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;C. numenius&lt;/em&gt;&lt;/jats&gt;&lt;em&gt;)&lt;/em&gt; and their sister taxon &lt;jats italic=&quot;&quot;&gt;&lt;em&gt;Gnathonemus petersii&lt;/em&gt;&lt;/jats&gt; with markedly different snout morphologies and EODs using hybrid capture/HTS DNA metabarcoding of their stomach contents. Our approach allowed for high taxonomic resolution of prey items, including benthic invertebrates, allochthonous invertebrates and vegetation. Comparisons of the diet compositions using quantitative measures and diet overlap indices revealed that all species are able to exploit multiple food niches in their habitats, that is fauna at the bottom, the water surface and the water column. A major part of the diet is larvae of aquatic insects, such as dipterans, coleopterans and trichopterans, known to occur in holes and interstitial spaces of the substrate. The results indicate that different snout morphologies and the associated divergence in the EOD could translate into different prey spectra. This suggests that the diversification in EOD and/or morphology of the feeding apparatus could be under functional adaptation.&lt;/jats&gt;&lt;/p&gt;
