Abstract
The hyperiid amphipods have been examined from an extensive series of depthstratified bongo net tows taken at 28°N; 155°W in the North Pacific central gyre, an open-ocean ecosystem. Seventy-nine samples from 6 depth ranges produced 14, 581 individuals belonging to 13 families, 42 genera, and 83 species. Data on depth distributions, rank orders of abundance, sex ratios, and vertical migration are presented. Most of these species are shown to be reproductively active in the gyre, and there appears to be no seasonality to their reproductive behavior. No species endemic to the gyre are yet known.
