Datasets used to explore co-variation patterns between morphological traits and trophic niche in co-occurring <em>Niphargus</em> amphipods from five groundwater caves of the Dinaric Karst, Europe. We quantified gnathopod size and shape by means of morphometric measurements and assessed isotopic niche, trophic position, and carbon signatures using nitrogen (δ<sup>15</sup>N) and carbon (δ<sup>13</sup>C) stable isotopes. We provide morphometric and isotopic data for <em>Niphargus</em> specimens, and isotopic data for food resources sampled in the caves.
