This deep-sea environment is characterized by constant and relatively warm temperature (13 ± 0.5°C) throughout the year. Two independent daily-ration estimates were produced: First, an actual daily ration was obtained by computing the weight of the fresh food items, yielding a value of 2.588 g wet food weight per 100 g shrimp wet weight. Second, the daily ration was estimated by the models of Eggers and Elliot and Persson. Daily rations for A. antennatus computed from these models ranged between 1.666 (±1.193) and 2,315 (±0.924) g wet food weight per 100 g shrimp wet weight, or between 0.130 (±0.115) and 0.223 (±0.091) g dry food weight per 100 g shrimp wet weight. The results of the 3 daily-ration models were compared and tested by bootstrapping; they did not differ significantly. Our results are compared with daily rations reported for other marine organisms. The feeding ecology of A. antennatus is discussed in relation to the food-limited deep-sea environment which this shrimp inhabitsPeer ReviewedInter ResearchConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2019201919972019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/184178reponame:DIGITAL.CSIC.
