Hyperiidea
hyperiid amphipods
Hyperiidea is a suborder of exclusively marine amphipod crustaceans characterized by large eyes and a planktonic lifestyle. Unlike other amphipod suborders, they do not occur in freshwater. The group comprises approximately 284 species across 20-23 families. Most species are associated with gelatinous zooplankton as parasites or predators of salps and jellyfish, though some members such as Themisto gaudichaudii are free-swimming predators of copepods and other small planktonic animals.
