Ever had to find your friend in a crowd? Imagine at a festival your mate saying: "I'll be wearing a yellow t-shirt by the hotdog stall behind the jazz stage." Using this information, you could walk around listening out for the romping double bass, and as you get closer and start to hear the trills of the trumpet, begin to sniff out the frying onions and sizzling sausages. Once you have located the hotdog stand, you only need to look for a bright yellow t-shirt and you will find your friend....

What Makes A Robot Fish Attractive?
2012-03-02 04:41:26

Probing the largely unexplored question of what characteristics make a leader among schooling fish, researchers have discovered that by mimicking nature, a robotic fish can transform into a leader of live ones. Through a series of experiments, researchers from Polytechnic Institute of New York University (NYU-Poly) aimed to increase understanding of collective animal behavior, including learning how robots might someday steer fish away from environmental disasters. Nature is a growing...

University of Miami team sinks teeth into larval life of barracuda, sennets For anglers and boaters who regularly travel the coasts of Florida the great barracuda (Sphyraena barracuda) is a common sight. Surprisingly, however, very little is known about the early life stage of this ecologically and socio-economically important coastal fish. In the journal Marine Biology, lead author Dr. Evan D'Alessandro and University of Miami Rosenstiel School of Marine & Atmospheric Science...

The majority can benefit when individuals are uninformed From shoals of fish to human society: social organisms need to make collective decisions. And it is not always the majority that prevails. In some cases, a small, resolute group may succeed in bending the whole community to their will. Using computer models and behavioral studies of fish, a team of scientists, including researchers from the Max Planck Institute for the Physics of Complex Systems in Dresden, has discovered that...

Fish Follow The Rules To School

The rules of school are simple: it is all about watching the kid nearest to you and making sure you do what they do. Researchers at the mathematics department at Uppsala University, together with biologists at Sydney University have shown that fish apply similar rules when traveling in small shoals. Some of the most mesmerizing sights in the natural world are seen in the collective motion of fish schools and shoals. In the ocean, vast schools of hundreds of thousands of fish can form which...

New research suggests that hitch-hiking, once believed to be the exclusive domain of beat poets and wanderers, is in fact an activity that daring members of the animal kingdom engage in. And it may lead to a serious ecological problem. Dr David Chapple, Dr Bob Wong and Sarah Simmonds from Monash University's School of Biological Sciences, have published two complementary studies on invasive species, which are taking the opportunity to jump on board freight and cargo transports to explore,...

Colossal Aggregations Of Giant Alien Freshwater Fish As A Potential Biogeochemical Hotspot

[ Watch the Video ] Many different types of animals come together to form vast groups — insect swarms, mammal herds, or bird flocks, for example. Researchers in France added another example to the list, reported Oct. 5 in the online journal PLoS ONE: the huge Wels catfish, the world's third largest and Europe's largest fresh-water fish. Researchers observed these fish in the Rhone River from May 2009 to Feb. 2011 and found that they formed dense groups of 15 to 44 individuals,...

Image 1 - Salmon, Other Fish Predators Rely On 'No Guts, No Glory' Survival Tactic
2011-09-18 05:36:09

  The phrase "no guts, no glory" doesn't just apply to athletes who are striving to excel. Salmon and other fish predators take the adage literally, by having up to three times the "gut" capacity they need on a daily basis just so they can "glory" when prey is abundant, University of Washington researchers have discovered. It's a previously unrecognized survival tactic that might apply to other top predators, such as wolves, lions and bears, according to Jonathan Armstrong, a UW...

Biologists worldwide subscribe to the healthy herds hypothesis, the idea that predators can keep packs of prey healthy by removing the weak and the sick. This reduces the chance disease will wipe out the whole herd, but could it be that predators can also make prey populations more susceptible to other predators or even parasites? Biologists at the Georgia Institute of Technology have discovered at least one animal whose defenses against a predator make it a good target for one opportunistic...

Biologists found resemblances between a peloton of cyclists in the Tour de France and a school of fish, reports the Guardian. Fish swim as though they were cyclists, where as fish at the back of a school use the slipstream created by the stronger fish out in front to swim with less effort. The study found that the position of a fish in the school depends on how physically fit it is.  The fittest swim at the front, where they get the pick of the best food. The less-fit fish swim...

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...
