Detected prey
Identified prey zOTUs belonged to a broad range of eukaryote taxa including metazoans (e.g. Chaetognatha, Urochordata, Rotifera), fungi (Ascomycota, Basidiomycota), ciliates (e.g. Spirotrichea), dinoflagellates (Dinophyceae, Dinophyta_X), heterokonts (e.g. Bacillariophyta, Chrysophyceae, Labyrinthulea) and radiolarians (Acantharea). Mean relative abundances of prey are available in the supplementary files (Table S4), and prey compositions are presented in greater detail in an upcoming publication (Flo et al., unpublished data).
