In 1997, scientists at the Center for Neurodynamics at the University of Missouri - St. Louis demonstrated that special sensors covering the elongated snout of paddlefish are electroreceptors that help the fish detect prey by responding to the weak voltage gradients that swimming zooplankton create in the surrounding water. Now some of the same researchers have found that the electroreceptors contain oscillators, which generate rhythmical firing of electrosensory neurons. The oscillators...

Daphnia magna

  Oregon State University (OSU) researchers have discovered a breed of freshwater zooplankton that they say can help combat a fungus that has been devastating amphibian populations around the world. According to the International Business Times, this particular species of zooplankton is known as Daphnia magna, a variety of aquatic flea from the genus Daphnia. They say that these organisms "could provide a desperately needed tool for biological control of the deadly fungus whose...

One riddle solved on cholera by examination of four major river basins shows when water flow went up, nutrients in the water were associated with increase in cholera cases An examination of the world's largest river basins found nutrient-rich and powerful river discharges led to spikes in the blooms of plankton associated with cholera outbreaks. These increased discharges often occur at times of increased temperature in coastal water, suggesting that predicting global warming's potential...

Zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low almost nothing can survive - but they may run into trouble as these areas expand under climate change. "OMZs are very difficult places to survive," says PhD researcher Leanne Elder from the University of Rhode Island. "But we have discovered that Phronima sedentaria have adapted in two specialized ways. Firstly they suppress their metabolism, which is very...

Tiny marine organisms called zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low that almost nothing can survive, but they may run into trouble as these areas expand due to climate change. "Oxygen minimum zones are very difficult places to survive," said University of Rhode Island doctoral student Leanne Elder. "But we have discovered that these tiny animals have adapted in two specialized ways. First, they...

A new study by researchers at the Virginia Institute of Marine Science (VIMS) shows that jellyfish are more than a nuisance to bathers and boaters, drastically altering marine food webs by shunting food energy from fish toward bacteria. An apparent increase in the size and frequency of jellyfish blooms in coastal and estuarine waters around the world during the last few decades means that jellies' impact on marine food webs is likely to increase into the future. The results of the study, led...

Phytoplankton peak arising up to 50 days early, with unknown impacts on marine food chain and carbon cycling Warming temperatures and melting ice in the Arctic may be behind a progressively earlier bloom of a crucial annual marine event, and the shift could hold consequences for the entire food chain and carbon cycling in the region. Scientists at Scripps Institution of Oceanography at UC San Diego, along with colleagues in Portugal and Mexico, plotted the yearly spring bloom of...

Some fish are made out of maple leaves A distant relative of shrimp, zooplankton are an important food source for fish and other aquatic animals. Long characterized as algae feeders, a new study published this week in the Proceedings of the National Academy of Sciences reports that nearly a third of zooplankton diets are supported by material that originates on land in lake watersheds. The study brings scientists one step closer to clarifying the role that watershed inputs play in aquatic...

A study carried out over 50 years by an international team, with the participation of the Balearic Oceanography Centre of the Spanish Institute of Oceanography (IEO) has confirmed an increase in the size and intensity of proliferations of the jellyfish Pelagia noctiluca. There are several complex reasons for this - over-fishing and the current increase in sea water temperatures. "Since 2002, these organisms have become increasingly frequently found in the north east Atlantic in winter, since...

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...

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...
