Fish Can Remember Where They Were Fed 12 Days Later
2014-07-02 03:18:58

Society for Experimental Biology It is popularly believed that fish have a memory span of only 30 seconds. Canadian scientists, however, have demonstrated that this is far from true – in fact, fish can remember context and associations up to twelve days later. The researchers studied African Cichlids (Labidochromis caeruleus), a popular aquarium species. These fish demonstrate many complex behaviors, including aggression, causing the scientists to predict that they could be capable...

A fast fish with a huge impact Globalization is breaking down barriers – also for plants and animals on the lookout for new homes. Rivers are also changing, in particular through the introduction of non-native species, often brought in by passing ships. In the Danube River, scientists have been observing a fish species conquering a new habitat and creating a totally new ecosystem in the process. Recent decades have seen massive changes to many river systems. To improve passage for...

Antarctica Fish Threatened By Climate Change
2012-02-14 04:19:52

A Yale-led study of the evolutionary history of Antarctic fish and their "anti-freeze" proteins illustrates how tens of millions of years ago a lineage of fish adapted to newly formed polar conditions — and how today they are endangered by a rapid rise in ocean temperatures. "A rise of 2 degrees centigrade of water temperature will likely have a devastating impact on this Antarctic fish lineage, which is so well adapted to water at freezing temperatures," said Thomas Near, associate...

  Captive breeding could transform the saltwater aquarium trade and save coral reefs Marine biologists at The University of Texas at Austin Marine Science Institute are developing means to efficiently breed saltwater aquarium fish, seahorses, plankton and invertebrates in captivity in order to preserve the biologically rich ecosystems of the world's coral reefs. These scientists believe their efforts, and those of colleagues around the world, could help shift much of the $1...

One of the world's strangest animals — a unique fish that lives on land and can leap large distances despite having no legs — has a rich and complex social life, a new study has found. The odd lifestyle of the Pacific leaping blenny (Alticus arnoldorum) has been detailed for the first time in research findings that throw new light on how animal life first evolved to colonies the land. The Pacific leaping blenny is a marine fish yet is terrestrial in all aspects of its daily...

Researchers have experimentally shown that some species of reef fish will enact punishment on the parasitic saber-tooth blennies that stealthily attack them from behind and take a bite, even though their behavior offers no immediate gain. The study, published online on November 4 in Current Biology, a Cell Press publication, shows that punishment ultimately serves all members of the reef fish species well. In future attacks, blennies are more likely to go after "free-riding" individuals that...

Stargazer, Uranoscopidae
2014-06-09 09:36:03

The stargazer is a family of fish of the Uranoscopidae family. There are about 51 species of stargazer fish in eight genera. They are found worldwide in shallow saltwater. One species of stargazer is extinct, the Astroscopus countermani. A cranium was found of this species in the Calvert Cliffs of Maryland, and is very similar to the living stargazers of today. The stargazer has eyes on top of its large head. The mouth is also large and faces upward. A trait of the stargazer is that it...

Banded Archerfish, Toxotes jaculatrix
2013-10-17 09:59:34

The Banded Archerfish (Toxotes jaculatrix) is a brackish water perciform fish of the archerfish genus Toxotes. Its coloration is silvery and has a dorsal fin towards the posterior end. It has distinctive and semi-triangular markings located along its side. It is best known for its ability to spit a jet of water to “shoot down” its prey. Larger specimens might be able to hit their prey 6 feet 7 inches to 9 feet 10 inches away. The archerfish might reach the displaced prey within 50...

The Zebra tilapia (Tilapia buttikoferi) is a fish inhabitant to West Africa, specifically Liberia. This fish is an African tilapiine cichlid. The Zebra tilapia is a freshwater fish that is inclined to streams and rivers. For both aquatic and nutritious reasons, this fish has been imported and bred all over the world. The Zebra tilapia is a stunning cichlid. It is usually white or yellow with black stripes. This fish varies from light to black based on its mood. The stripes seem to fade...

The Leatherjacket Fish (Oligoplites saurus) also known as the Skipjack or Leather Jack, is a species of fish in the Carangidae family. Leather Jack may refer to other fish as well and is loosely used here. This fish inhabits shallow waters of the Gulf of Mexico and southern Atlantic coast. The Leatherjacket Fish is seldom larger than 12 inches, although there have been reports of such specimens growing longer. The body is slender and compressed. It has a pointed head and large jaws for...
