Abstract: Caprella californica, C. brevirostris, and C. penantis may occur together on the hydroid Aglaophenia struthionides. Caprella incisa may occur on the bryozoan Tricellaria occidentalis growing in close proximity. Cleaning and feeding behavior of these caprellid species were compared under conditions of simulating natural water flow. All species were seen to engage in filter feeding and some in scraping and macrophagous feeding. Quanititative comparison of the main components of feeding behavior in the three species on Aglaophenia shows little obvious evidence of resource partitioning, and the role of motility and position are considered.
