The eyes of mesopelagic crustaceans
Cell and Tissue Research, 1978In Streetsia challengeri left and right eyes have fused and become a single cylindrical photoreceptor, which occupies the basal half of a forward directed head projection. This unusual compound eye consists of approximately 2500 ommatidia, which are arranged in such a way that the animal has almost circumferential vision, but cannot look ahead or ...

Ink utilization by mesopelagic squid
Marine Biology, 2007Remotely operated vehicle dive video recordings of deep-sea squid ink release were examined to determine species, ink release type, release depth, and accompanying behavior/s. Ink release was commonly observed between the surface and 1,842.1 m in Monterey Bay, CA, and surrounding waters.

Sensory Brain Areas in Mesopelagic Fishes
Brain, Behavior and Evolution, 2001Four areas of the brain that receive primary projections from chemical senses ([1] olfactory bulb, [2] facial and vagal lobes), the eye ([3] optic tectum), and somato- and mechanosensory systems such as the lateral line, vestibular and auditory systems ([4] trigeminal and octavolateral regions) have been studied and relative size differences used to ...

Proximate composition of Antarctic mesopelagic fishes
Marine Biology, 1990Eleven mesopelagic fish species from the Weddell/Scotia Sea region of the Antarctic captured during the austral spring 1983, austral fall 1986, and austral winter 1988, were analyzed for proximate composition. Water, ash level, protein, lipid and carbohydrate were examined in relation to depth of occurrence and season.

Mesopelagic microplankton of the Arabian Sea
Deep Sea Research Part I: Oceanographic Research Papers, 2003Abstract The Arabian Sea is notable for its dramatic monsoonal effects on euphotic zone biogeochemical processes and the large spatial extent of its mesopelagic oxygen minimum zone. As part of the US Joint Global Ocean Flux Study Arabian Sea project, we sampled microplankton (organisms 20–200 μm including diatoms, dinoflagellates, ciliates ...

2007
A collaborative effort called MEDUZA was established in 2002 between US, Croatian and Slovenian scientists to investigate gelatinous zooplankton ecology in the southern Adriatic Sea. In conjunction with the MEDUZA program, several cruises were made to a 1200 m depth station characterized by clear, oligotrophic surface waters largely devoid of metazoan ...

Target strengths of two abundant mesopelagic fish species
The Journal of the Acoustical Society of America, 2015Mesopelagic fish of the Myctophidae and Sternoptychidae families dominate the biomass of the oceanic deep scattering layers and, therefore, have important ecological roles within these ecosystems. Interest in the commercial exploitation of these fish is growing, so the development of techniques for estimating their abundance, distribution and ...

Broadband acoustic quantification of mesopelagic zooplankton
The Journal of the Acoustical Society of America, 2019In addition to its critical role in biogeochemical cycling, the mesopelagic zone has the potential to become an important global fisheries resource. A growing number of studies have focused on estimating the global biomass of mesopelagic fishes, but that of mesopelagic zooplankton is far more uncertain.
