The Shocking Story Of How Some Fish Evolved Electric Organs
2014-06-27 07:06:34

redOrbit Staff & Wire Reports - Your Universe Online By sequencing the genome of the electric eel for the first time, researchers have discovered how certain types of aquatic creatures were able to develop organs that allow them to produce electricity outside of their bodies. Publishing a paper in the latest edition of the journal Science, scientists from Michigan State University, University of Wisconsin-Madison, University of Texas-Austin and the Systemix Institute explain how...

New Weakly Electric Fish Species Reflects Hope For Peace In Central Africa
2014-04-11 14:05:39

Pensoft Publishers Two new species of weakly electric fishes from the Congo River basin are described in the open access journal ZooKeys. One of them, known from only a single specimen, is named "Petrocephalus boboto." "Boboto" is the word for peace in the Lingala language, the lingua franca of the Congo River, reflecting the authors' hope for peace in troubled Central Africa. On a 2010 field trip to the Congo River of Democratic Republic of the Congo, in the riverside village of...

New Electric Fish

Lee Rannals for redOrbit.com - Your Universe Online A new species of electric fish has been discovered in the murky waters of the upper Mazaruni River in South America. Scientists reported in the journal Zoological Scripta that they discovered a species that they've dubbed Akawaio penak in the remote regions in northern Guyana during an expedition. The team analyzed tissue samples collected during the trip, and found that the fish represents not only a new species but also a new genus....

Weakly electric fish spend their lives bathed in their own internally generated mild electric field, interpreting perturbations in the field as objects pass through and when communicating with members of their own species through high frequency electric 'chirps'. Rüdiger Krahe, from McGill University, Canada, says, 'These fish are very cryptic and hard for us to understand because we don't have this electric sense'. Electric fish actively produce their weak electric fields;...

A novel way to ramp up biodiversity Bruce Carlson stands next to a fish tank in his lab, holding a putty colored Radio Shack amplifier connected to two wires whose insulation has been stripped. At the bottom of the tank a nondescript little fish lurks in a sawed-off section of PVC pipe. Carlson sticks the two bare wires into the tank. Suddenly we hear a rapid-fire pop, pop, pop, pop, pop, pop. The pops, which are surprisingly loud, sound rather like the static on an old-fashioned tube radio...

An aquarium in Utah is lighting its Christmas tree with the help of an electric eel. Electrodes in the water pick up the eel's voltage, powering the tree's multi-colored lights. Sandy, UT (PRWEB) December 22, 2010 The Living Planet Aquarium is shocking visitors with its Christmas display which uses an Electric eel to flash the lights on its tree. A Christmas display in the 'Journey To South America' gallery is blinking by using the energy generated by an electric eel in a nearby tank. "We...

Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses, University of Texas at Austin researchers have discovered. The fish generate electric fields to navigate, fight and attract mates in murky streams and rivers throughout Central and South America. They do so at night, while trying to avoid predators such as catfish that sense the electric fields....

Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper* by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. Applying modern engineering design tools to one of the basic units of life, they argue that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them. Artificial versions of the eel's electricity...

Male fish can amp up their electric fields to woo females and intimidate rivals, research now reveals. A number of fish can generate electric fields. Relatively few such electric fish pack strong enough jolts to defend themselves or stun prey - most just use their electrical discharges to help navigate the water or communicate in the dark. One weakly electric fish is the nocturnal gymnotiform fish (Brachyhypopomus pinnicaudatus), a toothless fish native to the Amazon basin....

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...

The Electric eel, Electrophorus electricus, is a species of fish. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is a top predator in its South American range. Despite its name it is not an eel at all but rather a knifefish. Taxonomy The species is so unusual that it has been reclassified several times. Originally it was given its own family Electrophoridae, and then placed to a genus of Gymnotidae alongside Gymnotus....

The Black Ghost knifefish, Apteronotus albifrons, is a tropical fish belonging to the ghost knifefish family (Apteronotidae). They originate in South America in the Amazon Basin in Peru and from Venezuela through Paraguay in the Paraná Rivers. They are sometimes found in aquaria. The fish is all black except for two white rings on its tail. It moves mainly by undulating a long fin on its underside. It will grow to a maximum length of 20 in (50 cm). The Black Ghost knifefish natively...
