In this experiment P. kofoidii was subjected to prey mixtures consisting of A. pseudogonyaulax (strain L4-B9) and A. catenella (strain Alex 5) or A. limii (strain Atay99Shio-02), whereby one prey was dyed with the fluorescent dye CMAC. The dye had no influence on the feeding behaviour of P. kofoidii and thus dye combinations of the same prey mixtures were combined. This dataset contains all data collected within this experiment including cell counts and ingested prey cells of P. kofoidii. The experiments were carried out on January 18, 2023 in the laboratories at the Alfred-Wegener-Institute in Bremerhaven, Germany.1.71128.1226.6756.63North Sea, Scottish east coastShioya Bay, Okinawa, JapanThyborøn, Limfjord, DenmarkGerman Federal Environmental Foundationhttps://doi.org/10.13039/100007636PhD ScholarshipHelmholtz Association of German Research Centreshttps://doi.org/10.13039/501100001656Changing-Earth_Subtopic_6.2Adaptation of marine life: From genes to ecosystems
