1. Feeding response exhibition in five marine crustaceans was observed in the presence of a range of concentrations of an amino acid mixture composed of equal parts DL alpha arnino-n-butyric acid, L-glutamic acid and taurine. Gnathophausiaingens, Ple

The bathypelagic mysid, Gnathophausia ingens Dohrn, lives aerobically at oxygen partial pressures as low as 6 torr in the oxygen minimum layer off southern California. This study is concerned with the O2 binding properties of this mysid's hemocyanin

Oxygen consumption rates were measured in 14 species of hydromedusae and 5 species of bathypelagic coronate scyphomedusae. Analysis of all individuals of all species of medusae showed the familiar pattern of decreasing specific oxygen consumption rat

On the basis of our experiments, it is clear that carbonic anhydrase (CA) plays an important role in the CO2-concentrating mechanisms in Riftia pachyptila. Plume tissue from freshly collected animals had the highest CA activity, 253.7 +/- 36.0 {mu}mo

Ikeda et al. (2006; Mar Ecol Prog Ser 322:199-211) declared that they were testing the 'visual interactions' hypothesis for the decline in metabolic rates with depth in midwater animals, but their data and data analysis are irrelevant to this hypothe

Metabolic rates and thermal tolerances of three species of mobile symbiotic molluscs (two provannid gastropods Alviniconcha sp. and Ifremeria nautilei; and the mussel Bathymodiolus brevior) from Lau Basin hydrothermal vents were measured. Thermal tol

Carbon fixation by sulfur-oxidizing chemosynthetic bacteria forms the base of the food chain in deep-sea (diffuse- flow) hydrothermal vent ecosystems. Temperature and the availability of oxygen and reduced sulfur are believed to be factors that contr

Riftia pachyptila lives in the unstable environment at hydrothermal vent sites along oceanic spreading zones in the Eastern Pacific. The tubeworm has a symbiosis with intracellular carbon-fixing and sulfide-oxidizing bacteria. Nitrate is the main sou

This study compared the scaling of the glycolytic enzyme lactate dehydrogenase (LDH) and the Krebs cycle enzyme citrate synthase (CS) in the swimming muscle and tentacle tissue of the mesopelagic coronate scyphomedusa Periphylla periphylla in two pop
