The relative predation by adult, female Tortanus on their own nauplii and on developmental stages of Acartia clausii was determined by offering pairs of prey at several relative and absolute abundances. Predation was most intense on adult Acartia, less so on juvenile Acartia (nauplii and immature copepodites), and least on naupliar Tortanus. There was no evidence of switching.
