Laboratory studies of feeding on zooplankton by Tenagomysis chiltoni were made to determine responses to prey density and whether they differed between prey species. Bosmina were readily taken and feeding rates increased linearly with prey density. Feeding rates on Calamoecia and Ceriodaphnia were lower; and very few Daphnia were captured. Responses to prey densities were not strongly linear with these species. In trials with pairs of prey over a range of ratios but constant total prey density, no switching of prey preferences occurred. Ease of capture as determined by prey size, agility and behaviour apparently dictated the diet of T. chiltoni under these circumstances.
