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 ...

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.

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

Remarkable heterogeneity in meso- and bathypelagic bacterioplankton assemblage composition

Limnology and Oceanography, 2006
We investigated meso- to bathypelagic (500–3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Ocean near the Hawaiian archipelago, at the San Pedro Ocean Time Series (SPOTS) station off southern California, and in the Coral Sea off eastern Australia ...

The biology of bathypelagic organisms, especially Crustacea

Deep Sea Research and Oceanographic Abstracts, 1972
Abstract An examination is made of the body sizes of species of euphasiidss, mysids, copepods and chaetognaths living in different bathymetric zones. The maximum body size of each species is used as a measure of its potential for growth in size. Bathypelagic euphausiids and mysids are shown to possess a much greater potential for attaining greater ...

Function of extra-ocular photoreceptors in bathypelagic cephalopods

Deep Sea Research and Oceanographic Abstracts, 1972
The photosensitive vesicles of four species of bathypelagic cephalopods are examined. In species of Bathyteuthis the vesicles appear to function in the detection of bioluminescent light from organisms located outside the visual field. In Galiteuthis phyllura the vesicles may function both in detecting bioluminescent light and down-welling surface light.

Composition of the swim-bladder gas in bathypelagic fishes

Deep Sea Research (1953), 1957
Abstract Measurements were made of swim-bladder size and gas composition on pelagic fish in the eastern Pacific. The physiological problem of vertical migration with a swim-bladder is discussed. It is concluded that some gas-containing fish migrate vertically but that net-collecting data is too fragmentary to determine if such fish are primarily ...

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 ...
