The deep oceans have yielded many mysteries that have puzzled people for centuries, from the giant squid to huge jellyfish that look like UFOs. To that list add a fish with totally transparent blood. http://phys.org/news284360076.html Biology Fri, 05 Apr 2013 05:54:43 EST news284360076 In the waters off Antarctica, algae grow and live in the sea ice that surrounds the southern continent-a floating habitat sure to change as the planet warms. As with most aquatic ecosystems, microscopic algae form the base of the Southern Ocean food web. Distinct algae populations reside in the sea ice surface layers, on the ice's underside, and within the floating ice itself. The algae that reside on the floating ice's underside are particularly important for the region's krill population, while those on the interior or surface layers are less accessible. How changing sea ice properties will affect the regional biology, then, depends on understanding how algae populations interact with the ice. http://phys.org/news275052085.html Space & Earth Tue, 18 Dec 2012 11:21:39 EST news275052085 Massive blue whales perform 360° rolls in order to take in the largest possible volume of krill according to research published in Biology Letters today. Whales also roll over when searching for krill, enabling them to identify where their prey are most densely collected.  http://phys.org/news273397753.html Biology Thu, 29 Nov 2012 08:10:02 EST news273397753 Returning briefly to the surface for great lungfuls of air, the underwater lifestyles of whales had been a complete mystery until a small group of pioneers from various global institutions – including Malene Simon, Mark Johnson and Peter Madsen – began attaching data-logging tags to these enigmatic creatures. Knowing that Jeremy Goldbogen and colleagues had successful tagged blue, fin and humpback whales to reveal how they lunge through giant shoals of krill, Simon and her colleagues headed off to Greenland where they tagged five humpback whales to discover how the animals capture and consume their prey: krill and agile capelin. Attaching individual tags behind the dorsal fin on three of the whales – to record their stroke patterns – and nearer the head in the remaining whales – to better measure head movements – the team successfully recorded high resolution depth, acceleration and magnetic orientation data from 479 dives to find out more about the animals' lunge tactics. Simon, from the Greenland Institute of Natural Resources, Madsen, from Aarhus University, Denmark and Johnsen from the University of St. Andrews, UK, report how whales choreograph their foraging lunges at depth in The Journal of Experimental Biology. http://phys.org/news269106865.html Biology Thu, 11 Oct 2012 00:20:01 EST news269106865 Thousands of crustaceans were found dead off the coast of Lima following the mystery mass death of dolphins and pelicans, the Peruvian Navy said Friday. http://phys.org/news257238869.html Biology Sat, 26 May 2012 08:14:48 EST news257238869 The importance of the under-ice habitat for Antarctic krill was probably under-estimated in the past and emphasise the susceptibility of this ecological key species to changes in the sea ice habitat induced by climate warming. This was the main conclusion of Antarctic research of IMARES, part of Wageningen UR, published on 23rd February 2012 in the online journal PLoS ONE. http://phys.org/news250414901.html Biology Thu, 08 Mar 2012 07:41:49 EST news250414901 It is possible to know a tree from its fruit, but is it possible to know a prey from its predator? The answer is YES with Antarctic krill and Antarctic fur seals. Scientists of the University of Science and Technology of China (USTC) detected changes in the number of krill from the hair of seals. http://phys.org/news241950892.html Space & Earth Thu, 01 Dec 2011 08:35:28 EST news241950892 Scientists have discovered that female Antarctic fur seals have an uncanny ability to return to within a body length of where they were born when it's time to breed. http://phys.org/news239011730.html Biology Fri, 28 Oct 2011 09:08:58 EST news239011730 (PhysOrg.com) -- Erich Fitzgerald, an Australian paleontologist, believes he has found the missing link between ancient toothed whales that caught and ate fish and modern baleen whales that eat by sucking in huge volumes of water and then filter out the krill and shrimp in it. http://phys.org/news232876209.html Biology Thu, 18 Aug 2011 08:50:33 EST news232876209 A new discovery reveals that the shrimp-like creature at the heart of the Antarctic food chain could play a key role in fertilising the Southern Ocean with iron – stimulating the growth of phytoplankton (microscopic plant-like organisms). This process enhances the ocean's capacity for natural storage of carbon dioxide. http://phys.org/news228974858.html Space & Earth Mon, 04 Jul 2011 05:15:34 EST news228974858 Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula. http://phys.org/news223131702.html Biology Wed, 27 Apr 2011 17:00:02 EST news223131702 Israeli researchers have demonstrated that krill and jellyfish, as tiny as they may be, play a big role in ocean mixing. http://phys.org/news214050323.html Space & Earth Wed, 12 Jan 2011 10:26:13 EST news214050323 (PhysOrg.com) -- Scientists have been studying how krill form into superswarms, which are among the largest gatherings of living creatures on Earth. http://phys.org/news174636686.html Biology Tue, 13 Oct 2009 09:50:05 EST news174636686 The National Oceanic and Atmospheric Administration (NOAA) today published a final rule in the Federal Register prohibiting the harvesting of krill in the Exclusive Economic Zone (EEZ) off the coasts of California, Oregon, and Washington. The rule goes into effect on August 12, 2009. Krill are a small shrimp-like crustacean and a key source of nutrition in the marine food web. http://phys.org/news166720076.html Biology Mon, 13 Jul 2009 16:40:02 EST news166720076
