Significant seasonal variations in surface circulation are driven by the East Asian Monsoon in the South China Sea (SCS). Seasonal variations in copepod and hyperiid communities following the monsoon have been reported. The mechanisms controlling these

As commensals and parasitoids of gelatinous plankton, hyperiid amphipods play unique and important ecological roles in pelagic food webs. Because the diversity and biogeography of this group in oceanic waters is poorly known, we examined diversity and

Data collected on large-scale surveys around the seamounts and islands off northeastern Brazil provide information on the hyperiid amphipod populations. Thirty-six species were identified. Most of the species belong to the Infraorder Physocephalata, representing
