Incredibly Gross New Species of Fish Found in Antarctica

Incredibly Gross New Species of Fish Found in Antarctica You might call it creepy, but scientists say these fish are just misunderstood.

A new species of electric eel with the most powerful shock of any animal ever discovered has been found in the Amazon . The creature is one of three species now confirmed to exist—for the last 250 years, since electric eels were first identified, it was thought there was just one species in the genus.

Electric eels use their shock tactics for a variety of reasons, including hunting prey, self-defence, and navigation. They generate electricity from three specialised electric organs that can emit charges of varying strengths for different purposes. But the discovery of the new species raises the possibility

In a study published in Nature Communications, researchers led by C. David de Santana, from the Smithsonian's National Museum of Natural History, analyzed over 100 fish collected across Greater Amazonia over recent years to find out if it is indeed just one species.

Amazon Joins Walmart in Saying Tesla Solar Panels Caught Fire

Supercharger station in Kettleman City, California, U.S., on Wednesday, July 31, 2019. Electric vehicles have been adopted rapidly in California, compared to the rest of the U.S., accounting for about 44% of total sales in 2018. On Friday, Amazon.com Inc. said a June 2018 blaze on the roof of one of its warehouses in Redlands, California, involved a solar panel system that Tesla’s SolarCity division had installed.

The average shock from an electric eel lasts about two-thousandths of a second. The pain isn’t searing “It’s quite literally shocking , when you discover new diversity in such an eye-catching fish first The electric eel has long excited the popular imagination. But its biodiversity has been vastly

Genetic data has revealed several distinct electric eel species living throughout South America, including the most shocking eel (and animal) discovered yet. Scientists have assumed that the electric eel comprised a single species , ever since taxonomist Carl Linnaeus first described the

The electric eel—which is not a true eel, but rather a South American knifefish—can generate pulses of electricity it pushes through water to shock prey and defend itself. The ability of animals to produce electricity is known as bioelectrogenesis. Other species known to possess this ability include certain catfish, stargazers and rays. The electric eel, however, generates the biggest voltage—around 650 volts.

In the study, Santana and colleagues looked at the morphology of the electric eels collected, performed an analysis of their DNA and examined their geographical and ecological distributions.

The researchers examined 107 electric eels taken from waters across northern South America, measuring different parts of their body and The analysis also revealed that E. voltai could produce shocks up to 860 volts, higher than has been measured for electric eels or any other organism before.

A newly discovered species of electric eel produces an 860 volt shock , the highest charge of any known animal in the world. The creature is one of two extra species of the fish identified by scientists, who examined 107 specimens from across the Amazon rainforest. The newly discovered eel

Findings revealed not one but three distinct species of eel, which they have named Electrophorus electricus, Electrophorus varii and Electrophorus voltai. The latter was found to produce the biggest shock of all, reaching 850 volts. This is the biggest discharge produced by any bioelectrogenetic animal ever recorded. Each species was found to have individualized skulls, pectoral fins and arrangement of pores across its body.

The three were found to have slightly different ranges—E. electricus is generally found in the Guiana Shield, E. varii and the Amazon basin lowlands, while E. voltai tended to be found in the Brazilian Shield. The three creatures split from a common ancestor during the Miocene and Pliocene (23 to 2.5 million years ago), researchers say. E. varii split off around 7.1 million years ago, while E. voltai and E. electricus diverged about 3.6 million years ago—a time when the Amazon River changed course. The scientists think E. voltai's higher voltage is an adaptation because it lives in highland waters that are less conductive.

There are many ways to catch electric eels . Now the trick will be getting him off the hook without getting shocked . We should have brought rubber gloves, but then again, why spend money on that when a twig will do From where does the electric eel produce more voltage, the head, or the tail?

Scientists have long assumed there was only one species of electric eel . (After all, who needs more ?) But when a team of researchers examined more than 100 electric eels from South America’s Amazon Basin, it found that there are actually three species —one of which delivers the strongest shock ever

In a statement, Santana said the discovery of the new species could provide an insight into a new system for electrogenesis—when it was discovered, the electric eel helped inspire the design of the first-ever battery. "It could really have different enzymes, different compounds that could be used in medicine or could inspire new technology," he said.

"These fish grow to be seven to eight feet long. They're really conspicuous. If you can discover a new eight-foot-long fish after 250 years of scientific exploration, can you imagine what remains to be discovered in that region?"
