Considerations for the design of an epipelagic biomimetic electrostatic imaging element

Proceedings of the Sixth ACM International Workshop on Underwater Networks - WUWNet '11, 2011
We discuss the development and design of a Biomimetic Electrostatic Imaging (BEI) element for use in a future multichannel imaging instrument. Inspiration for electrostatic sensing is provided by the diverse species of fish that use passive and induced electric fields for hunting, defense, localization, and communication.

A Synthesis of Growth Rates in Marine Epipelagic Invertebrate Zooplankton

2003
We present the most extensive study to date of globally compiled and analysed weight-specific growth rates in marine epi-pelagic invertebrate metazoan zooplankton. Using specified selection criteria, we analyse growth rates from a variety of zooplanktonic taxa, including both holo- and mero-planktonic forms, from over 110 published studies.

The visual pigments of epipelagic and rocky-shore fishes

Vision Research, 1964
Abstract Visual pigments of eleven species of marine teleost fishes have been studied in aqueous digitonin extracts of dark-adapted retinae. Five species that occur in habitats along rocky coasts have “rhodopsins” with λ max near 500 mμ. In six epipelagic species the visual pigments are also “rhodopsins”, but there is a trend for λ max to be at

Predation, cover, and convergent evolution in epipelagic oceans

Marine and Freshwater Behaviour and Physiology, 1995
The factor of most importance to the structure of epipelagic oceanic communities is the absence of cover and the inability to hide from predators in surface waters during the day (Elton, 1939). Visual predation in an environment devoid of cover has resulted in convergent evolution into only six modal adaptive patterns.

Patterns of sarcodine feeding in epipelagic oceanic plankton

Journal of Plankton Research, 1991
The range of in situ prey composition was determined in marine planktonic acanthana, foraminifera and radiolana collected by divers, and quantitatively compared with the prey available, as determined by surface plankton hauls on cruises in the Florida Current, Gulf Stream and Sargasso Sea.

Epipelagic siphonophores off the east coast of South Africa

African Journal of Marine Science, 2005
This work represents the first systematic analysis of the common Siphonophora from the Agulhas Current (South-West Indian Ocean). A total of 56 species of siphonophores was collected from a series of three largely epipelagic cruises between Algoa Bay and the Tugela River along the east coast of South Africa. Although no readily identifiable Cystonectae

On reproductive strategies of the epipelagic octopods of the superfamily Argonautoidea (Cephalopoda: Octopoda)

Marine Biology, 2003
Females of Tremoctopus violaceus, Argonauta argo and Ocythoe tuberculata in the Aegean Sea have larger eggs than specimens from the western Mediterranean and open ocean; the most probable reason is a shift in the reproductive strategies of Argonautoidea from the Aegean Sea toward the K-side, because of the high stability of this habitat in contrast to ...

Acoustic characteristics of populations of epipelagic schooling fish

The Journal of the Acoustical Society of America, 1976
Pelagic schooled fish populations have acoustic characteristics derived from their individual reflection or backscattering properties, their tendency to school, the tendency of schools to be aggregated in groups, and the tendency for populations of different species to be aggregated in regions of high productivity.

EPIPELAGIC COPEPOD ASSEMBLAGES IN THE WESTERN CARIBBEAN SEA (1991)

Crustaceana, 2000
[Zooplankton samples were collected on a four-month schedule (February, March, May, August 1991) off the eastern coast of the Yucatan Peninsula, westernmost portion of the Caribbean Sea. Taxonomic analysis of the pelagic Copepoda yielded 89 species, Undinula vulgaris, Temora turbinata, and Farranula gracilis being the overall dominant forms.
