Bentheuphausia amblyops is a cosmopolitan bathypelagic euphausiid with a vertical range of from 280 to 7 000 m. Determinations of proximate and elemental composition show that B. amblyops has a more robust structure (lower water content and higher protein content) than is typical of other bathypelagic Crustacea. B. amblyops is a strong swimmer and is capable of employing its thoracic legs in raptorial fashion. Discrete depth trawls taken between depths of 400 and 2 500 m on a diel basis show no… 

Respiration and ammonia excretion of euphausiid crustaceans: synthesis toward a global-bathymetric model

It becomes evident that euphausiids are unique in that they maintain high metabolic rates and accumulate moderate amounts of energy reserves (lipids) when compared with global-bathymetric models for the metabolism and chemical composition of copepods and chaetognaths.

Respiration and ammonia excretion rates of 19–24 euphausiids from the epipelagic through bathypelagic zones of the world’s oceans were compiled. Body mass (expressed in terms of dry mass, carbon or

Effects of temperature on metabolism, growth and growth efficiency of Thysanoessa longipes (Crustacea: Euphausiacea) in the Japan Sea

The present results are compared with the previous data on Euphausia pacifica in relation to the body composition and habitat usage of these two trophically important species in the food web of the Japan Sea.

Metabolic rates of midwater crustaceans as a function of depth of occurrence off the Hawaiian Islands: Food availability as a selective factor?

The data are consistent with the hypothesis that lower metabolic rates at depth are due to the relaxation of selection pressures relating to visual predation near the surface, and are interpreted as indicating that the metabolic rates of midwater crustaceans are not adapted specifically to differing levels of primary production.

Astaxanthin, canthaxanthin and astaxanthin esters in the copepod Acartia bifilosa (Copepoda, Calanoida) during ontogenetic development [commun.]

Most probably, astaxanthin is the main pigment active in copepod lipid metabolism, and may be involved as antioxidants in rapid lipid metabolism in exogenously feeding stages.

Changes in carotenoid composition in different developmental stages of copepods: Pseudocalanus acuspes Giesbrecht and Acartia spp.

It is suggested that astaxanthin is the main active carotenoid in copepod metabolism and acts most probably as an efficient free radical quencher and may be involved in rapid metabolism of stored lipids in mostly unfeeding young nauplii.

Ocean deoxygenation and zooplankton: Very small oxygen differences matter

It is shown that, in the eastern tropical North Pacific OMZ, previously undescribed submesoscale oxygen variability has a direct effect on the distribution of many major zooplankton groups, prompting major unanticipated changes to midwater ecosystem structure and function.

Metabolic Potential of Deep-Sea Animals: Regional and Global Scales

It is concluded that a combination of these methods would enable one to estimate the in situ metabolic rates of all major pelagic zooplankton and micronekton groups and enable calculation of the contribution of these animals’ respiration to global carbon flux and be a first step in evaluating their total role in the global carbon cycle.



Circulatory adaptations to the oxygen minimum layer in the bathypelagic mysid Gnathophausia ingens.

These reports show that G. ingens is able to live aerobically at oxygen partial pressures of 6 mm Hg at an oxygen consumption rate of 0.8 mgO2/Kg wet wt/min, and use in intact crustaceans of newer, more sensitive techniques for the measurement of internal pressure and fluid velocities has now permitted more detailed analysis of crustacean circulatory dynamics.

The distribution of Pacific euphausiids

A study of the distribution of 59 euphausiid species in the Pacific Ocean, based upon oceanic surveys carried out from 1949 to 1961, finds some species that inhabit a mesopelagic zone between depths of about 500 and 1,500 meters and other species that are characteristically epipelagic, living mainly above 500–700 meters.

Chemical composition and buoyancy of midwater crustaceans as function of depth of occurrence off Southern California

The energy involved in maintaining an animal in the water column is generally insignificant compared to its overall activity and advantages of neutral buoyancy other than energy conservation may be more important selective factors for this characteristic.

Metabolism of an Antarctic Fish and the Phenomenon of Cold Adaptation

From various sources of data presented by Fry (1957), it is apparent that normal metabolic levels of fish usually lie, and an antarctic species continuously adapted to icecold temperatures should have its metabolic level at comparative temperatures displaced upward even more.

Metabolic characteristics of midwater zooplankton: Ammonia excretion, O:N rations, and the effect of starvation

The nature of protein catabolism in a wide range of species of midwater zooplankton was investigated, finding that G. ingens maintains a relatively uniform metabolic rate during starvation by relying more heavily on its large lipid stores than when being fed.

Observations on the nocturnal feeding of some mesopelagic decapod crustacea

Anomalies in feeding in relation to temporal changes in the depth distribution of predator and prey is described for 9 species of mesopelagic decapods, and it is concluded that the remains of Pleuromamma probably represent the food of the larger prey such as chaetognaths etc. which are eaten by the decapods.
