Bathypelagic Coelenterates1

Limnology and Oceanography, 1956
Four different kinds of hydrozoan medusae, two of scyphozoans, and four of siphonophores are recorded from three basins of southern California, largely in depths greater than 4000 feet. The records are based on photographs made with a special underwater camera which is described. These coelenterates show specific distributional patterns which appear to

Carbon Monoxide Production by a Bathypelagic Siphonophore

Science, 1964
A physonectid siphonophore, Nanomia bijuga , associated with a vertically migrating deep scattering layer, has been observed with a gas-filled float at depths in excess of 300 meters in the sea. This implies that gas is secreted and maintained in the pneumatophore against a diffusion gradient of 30 atmospheres or ...

Pigments of meso- and bathypelagic chaetognaths

Marine Biology, 1977
Pigments of the meso- and bathypelagic chaetognaths Sagitta macrocephala and Eukrohnia fowleri were studied by chromatographic analysis. Supplementary histological studies were also performed. Fat-soluble properties and absorption spectra of the chaetognath pigments indicated that all pigments were carotenoid, independent of chaetognath species or ...

DOC dynamics in the meso and bathypelagic layers of the Mediterranean Sea

Deep-Sea Research Part II: Topical Studies in Oceanography, 2010
Seven years (2001-2008) of dissolved organic carbon (DOC) vertical profiles were examined in order to assess the main processes determining DOC concentration and distribution in the meso- and bathypelagic layers of the Mediterranean Sea. As expected, DOC showed high and highly variable concentrations in the surface layer of 57-68 mu M (average values ...

Bioluminescence of bathypelagic fish from the strait of messina

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1976
Abstract 1. Photophores isolated from bathypelagic fish emit bright flashes (6 × 10 7 to 6 × 10 9 quanta/sec) lasting a few msec when they are electrically stimulated. In Argyropelecus, Diaphus and Ichthyococcus . the flashes are short, fatigable and have short latency.

Respiration of the bathypelagic fish Cyclothone acclinidens

Marine Biology, 1981
The respiration of 3 adult females of Cyclothone acclinidens was measured in situ. These numerically dominant fish of the meso- and bathypelagic zones were individually captured off southern California at a depth of 1300 m using a multiple-chambered slurp-gun respirometer operated from the submersible “Alvin”. Continuous oxygen consumption measurements

A bathypelagic pycnogonid

Deep Sea Research and Oceanographic Abstracts, 1962
Abstract The world-wide occurrence of the pycnogonid Pallenopsis calcanea Stephensen at depths of 650 to 2000 m indicates that this is a true bathypelagic species, although it lacks any obvious specialization for this environment. Its lack of specialization suggests that it is parasitic or commensal upon some larger bathypelagic organism, possibly ...

Adaptations of the Bathypelagic nemerteans

The American Naturalist, 1927
OF all the groups of organisms which recent investigations have discovered in the deep oceans, probably none have become more widely divergent from their littoral relatives and more particularly adapted for a free-swimrning life far beneath the surface of the water than have the nernerteans.

Zoogeography of the Bathypelagic Fish, Chauliodus

Systematic Biology, 1952
THE MID-DEPTHS of the oceans comprise a significant part of the volume of the biosphere, yet the conditions for life here are so different from those encountered by man that it is difficult to appreciate the factors limiting the distribution of the bathypelagic organisms living there. Catch records, however, indicate that many species are restricted in
