This is an essay about a new type of poisonous dart frog that was recently discovered that alters a chemical from the food they eat to create their poison and make it stronger.

Scientist have actually launch a poisonous salientian that takes a toxin from its prey and then changes the chemical to make it superabundance more deadly. There are at least trio species of what are called the Dendrobates frogs. They range from 4-to-5-centimeters long and they can be preen up in the New World tropics. The frogs modify an alkaloid to micturate genius thats closely five times as poisonous. The poison, hotshot of a class called pumiliotoxins, ends up as a preventative comp integritynt in the frogs hide. Its an important thing, showing how chemistry connects the life of hotshot(a) organism to other. Even though scientists have put together that a couple of(prenominal) animals and insects other than frogs customize a basic toxin for different purposes, they havent found any other examples of improving a defensive weapon. finding that several(prenominal) frogs change the toxins they have eaten came as a bewilderment to the scientists who were s tudying dart-poison frogs, which belong to the family that includes Dendrobates. Frogs in three other families in South America, Australia, and Madagascar also carry poisons in their skin stock-still when zoos and aquariums raise these supposedly deadly creatures, frogs from all scarcely peerless Australian genus grow up harmless. Two scientist were working with an alkaloid called pumiliotoxin 251D, one of the skin toxins of the frog Dendrobates auratus. The scientists produced both the form of the alkaloid found in record plus a mirror-image form. The scientist dusted the formula on to some termites and supply them to the captive frogs. When the scientists later analyzed the skins of the frogs who were fed the spiced insects, about 80 percent of the natural form of 251D had been converted to another toxin, called allopumiliotoxin 267A but the unnatural form of 251D showed up unchanged in the frogs skin.
