Despite a 30-year warming trend, the last three years in the Bering Sea have been the coldest on record. A University of Alaska Fairbanks scientist says that the cold temperatures have helped produce larger zooplankton in the Bering Sea, which may be changing the way Walleye pollock are feeding. Alexei Pinchuk, research professional at the UAF Seward Marine Center, has spent the last three years gathering zooplankton samples in the Bering Sea. He and his colleagues have been looking at how...

Despite its primitive structure, the North American comb jellyfish can sneak up on its prey like a high-tech stealth submarine, making it a successful predator. Researchers, including one from the University of Gothenburg, have now been able to show how the jellyfish makes itself hydrodynamically 'invisible'. The North American comb jellyfish Mnemiopsis leidyi has long been known to consume vast quantities of zooplankton. A few years ago the species became established in Northern Europe. Like...

A new study co-authored by professor Kam Tang of the Virginia Institute of Marine Science reveals that tiny aquatic organisms known as "water fleas" play an important role in carrying hitchhiking bacteria to otherwise inaccessible lake and ocean habitats. The article, "Bacteria dispersal by hitchhiking on zooplankton," appeared in the June 29 issue of the Proceedings of the National Academy of Sciences. It was co-authored by scientists from the Leibniz-Institute of Freshwater Ecology and...

Research suggests that the amount of phytoplankton found in the top layers of the ocean has declined markedly over the last century. Scientists wrote in the journal Nature that the decline appears to be linked to rising water temperatures. The researchers looked at records of the transparency of sea water, which is affected by the plants.  The decline could be ecologically significant as plankton sit at the base of marine food chains. This is the first study that has attempted a...

Striking global changes at the base of the marine food web linked to rising ocean temperatures A new article published in the 29 July issue of the international journal Nature reveals for the first time that microscopic marine algae known as "phytoplankton" have been declining globally over the 20th century. Phytoplankton forms the basis of the marine food chain and sustains diverse assemblages of species ranging from tiny zooplankton to large marine mammals, seabirds, and fish. Says lead...

Onboard the U.S. Coast Guard Healy, June 29 -- "I think there are quite a lot of particles in the water today." That's the analysis from Dariusz Stramski, a scientist onboard the U.S. Coast Guard Cutter Healy for NASA's ICESCAPE mission in the Arctic's Chukchi Sea. The five-week mission, NASA's first oceanographic field campaign, is studying the physics, chemistry and biology of the ocean and ice within a changing Arctic. Stramski, from the Scripps Institution of Oceanography, stirred a flask...

Adding nutrients to the sea could decrease viral infection rates among phytoplankton and enhance the efficiency of the biological pump, a means by which carbon is transferred from the atmosphere to the deep ocean, according to a new mathematical modelling study. The findings, published in the Journal of Theoretical Biology, have implications for ocean geo-engineering schemes proposed for tackling global warming. Tiny free-floating algae called phytoplankton dominate biological production in...

Computer simulations performed by researchers at the National Oceanography Centre and the University of Glasgow show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean. Tiny free-floating marine plants called phytoplankton live in vast numbers in the sunlit upper ocean. Through the process of photosynthesis, they build carbon compounds such as sugars starting with just water and carbon dioxide, which is thereby drawn down from the...

Researchers at Woods Hole Oceanographic Institution (WHOI) have developed two advanced broadband acoustic systems that they believe could represent the acoustic equivalent of the leap from black-and-white television to high-definition color TV. For oceanographers, this could mean a major upgrade in their ability to count and classify fish and to pinpoint tiny zooplankton amid seas of turbulence. Lead authors Tim Stanton and Andone Lavery in the Department of Applied Ocean Physics and...

Results of Northwest Atlantic Field Program Could Be Applied Worldwide A three-year field program now underway is measuring carbon distributions and primary productivity in the Northwest Atlantic Ocean to help scientists worldwide determine the impacts of a changing climate on ocean biology and biogeochemistry. The study, Climate Variability on the East Coast (CliVEC), will also help validate ocean color satellite measurements and refine biogeochemistry models of ocean...

Bennett’s feather star, Oxycomanthus bennetti
2013-08-04 08:28:29

Bennett's feather star is a suspension feeder that grows to be about 1 foot with 31-120 arms extending upward from the body. The star catches the food, usually phytoplankton and zooplankton, with tubed feet located on the outside of the arms. Yellow, Brown, Green and Purple are the most common colors for the Bennett's feather star. The star will remain attached to the seabed by a stalk until it reaches maturity and then becomes free-living by breaking off from the stalk. The Bennett's...

Black Sea Cucumber, Holothuria forskali

Image Caption: Black Sea Cucumber, Holothuria forskali. Credit: Rpillon/Wikipedia (CC BY-SA 3.0) The black sea cucumber (Holothuria forskali), also known as the cotton-spinner, is a species that can be found in the Mediterranean Sea and eastern areas of the Atlantic Ocean. Its range includes the waters around the Azores and the Canary Islands. It prefers to reside in shallow waters at depths of up to 164 feet and can be found on rocky, vertical surfaces. In 1969, Rowe classified it within...
