Whale sharks (Rhincodon typus) are often thought to be solitary behemoths that live and feed in the open ocean. Scientists at the Smithsonian Institution and colleagues, however, have found that this is not necessarily the case, finding that whale sharks can be gregarious and amass in the hundreds to feed in coastal waters. Aggregations, or schools, of whale sharks have been witnessed in the past, ranging from several individual sharks to a few dozen. However this new research, which involved...

NSF CAREER awardee studies the behavior of schooling fish and creates biologically inspired robots that may someday help preserve marine life Scientists have long turned to nature for inspiration and innovation. From unlocking the secrets of spider silk to create super-strong materials to taking hints from geckos for new adhesives, clues from the natural world often lead to advances in our practical world. But the relationship between engineering and nature has been largely one-directional,...

Blue whales eat 90 times more energy when diving than they use, thanks to big mouths Diving blue whales can dive for anything up to 15 minutes. However, Bob Shadwick from the University of British Columbia, Canada, explains that blue whales may be able to dive for longer, because of the colossal oxygen supplies they could carry in their blood and muscles, so why don't they? 'The theory was that what they are doing under water must use a lot of energy,' says Shadwick. Explaining that the...

When fish or tiny, shrimp-like krill get together, it appears they follow the same set of "rules." According to a new study published online on September 16th in Current Biology, a Cell Press publication, shoals of fish and swarms of krill hang out in groups that take on the same overall shape; it's not a simple sphere, a cylinder, or ovoid, but something more akin to an irregular crystal, the researchers say. "The fact that several species of fish and krill that live in very different...

Ever wondered how cockroaches seem to know the best place to grab a meal? New research at Queen Mary, University of London suggests that, just like humans, they share their local knowledge of the best food sources and follow 'recommendations' from others. It is often striking how little we know about our closest neighbor. Until now, it was assumed that cockroaches forage on their own to find food and water. However, this work shows how groups of the insects seem to make a collective choice...

Going more miles per gallon with your brain The hunting strategy of a slender fish from the Amazon is giving researchers more insight into how to balance the metabolic cost of information with the metabolic cost of moving around to get that information. A new study from Northwestern University's McCormick School of Engineering and Applied Science answers the question: In behaviors in which you have to move to get information, when should the animal spend more energy on locomotion versus...

Scientists say that fish are being threatened by man-made noise pollution. The scientists reviewed the impact of noise made by oil and gas rigs, ships, boats and sonar on fish species around the world. They say that rather than live in a silent world, most fish hear well and sound plays an active part in their lives. The increasing noise pollution may severely affect the distribution of fish, as well as their ability to reproduce, communicate and avoid predators. "People always just...

Fish alter their movements when under threat from predators to keep closer together and to help them to blend into the crowd, according to new research headed by scientists at the University of York. Researchers in the York Centre for Complex Systems Analysis (YCCSA), based in the University's Department of Biology, used a combined computer simulation and experimental study of group behavior to discover that shoaling fish co-ordinate their movements more frequently when under threat. They...

In the open ocean, species of large predatory fish will swim and hunt for food at various depths, which leads to unique diets in these fish. Oceanographers and geologists in the School of Ocean and Earth Science and Technology (SOEST) at the University of HawaiÊ»i at Mānoa (UHM) and colleagues have found that those fish that hunt deeper in the open ocean have higher mercury concentrations than those that feed near the surface of the ocean because...

The Atlantic herring, Clupea harengus, is the one of the most abundant species of fish on the planet. They can be found on both sides of the Atlantic Ocean congregating together in large schools (or swarms). They can grow up to 17.72 in (45 cm) in length and weigh more than 1.1 lb (0.5 kg). They feed on copepods, krill and small fish, and their natural predators are seals, whales, cod and other larger fish. The Atlantic herring fishery has long been an important part of the economy of New...

The Blue runner (Caranx crysos) is a fish found along the coastlines of the Atlantic Ocean, mostly in the inland waters of the east coast of North America and the west coast of Africa. The fish has a rounded body shape and can grow to up to 27.56 in (70cm) long and weigh more than 11 lb (5kg). The body is silvery blue in color with a large eye. Blue runners are known as very fast and aggressive fish, traveling in schools and eating smaller fish and invertebrates. Schools may also pick...
