Measurements were made of the rates at which the ctenophores Pleurobrachia bachei and Bolinopsis microptera feed on copepods. The data were used to ascertain selectivity and rates of procurement of food in the natural habitat. Both ctenophores selected smaller prey (Pseudocalanus minutus) over larger prey (Ephilabidocera amphitrites). P. bachei selected, whereas B. microptera did not appear to select older over younger stages of development of P. minutus. B. microptera fed on smaller prey at a greater rate than did P. bachei.
