The globally ubiquitous lysianassoid amphipod, Eurythenes gryllus, has been shown to consist of multiple genetically distinct cryptic taxa, with depth considered a major driver of speciation and morphological divergence. Here we examine morphological

Laboratory experiments were carried out to measure standard (starved animals) and active (animals exposed to food odour) metabolic rates of the deep-sea amphipod Eury-thenes gryllus. Six individuals could be kept alive and in good condition in the lab

Amphipods Eurythenes gryllus were collected at 7800 m depth in the Atacama Trench (South Pacific) for studying their biochemical composition (in terms of proteins, lipids and carbohydrates and fatty acid content) and to gather information on bioenergetic

Eurythenes gryllus, a large, cosmopolitan, bentho-pelagic amphipod, was captured in high numbers during a 3 year sampling program in the central North Pacific. Instars were determined by using a combination of morphological criteria and size frequency

The nearly ubiquitous deep-sea amphipod, Eurythenes gryllus (Lichtenstein), occurs throughout the central North Pacific basin, and has recently been collected from the crests of three bathyal seamounts. Questions of the dispersal capabilities of the species
