Poison dart frogs

Thesis frogs live only in shares of Central and South America. They are bright red, yellow or orange stripes often colored with bold gold bars. Very small (only 5.2 cm long reaching leg) and only a few grams of weight, Seema helpless. But their skin glands produce toxins victims of the strongest in the world of animals: batrachotoxin, batrachos the ancient Greek word poison frogs and toxins). The name was given by the American scientist John Delly and Bernard Whitcup Given who several tests to determined action de cette The potent toxin carried out.
There aussi neurotoxins that attack the nervous system. Batrachotoxin, especially a nerve poison. Only a drop of this substance entered the body can not function the victim Cdn block the transmission of nerve impulses and heart.

Spiders are often attracted by the beautiful poison dart frogs and trying to kill them years approach. However, it is too late: the toxin released through the skin into the acorns frog in the back and around the ears served ICT has purpose. The spider died and it is suitable for a meal of the frog. If these little amphibians are threatened (if it is touched by a human hand or bitten by a carnivorous animal) ICT reflexively expel toxins poison acorn by a number of channels. The substance has a bitter taste and odor-specific, sharply This causes vomiting. For this, year has bitten the animal frog, the soon to leave on them and from his mouth. poisonous frogs aussi eat other insects, millipedes and worms. They are a very important part of the ecosystem because they control the population of several pests.
The habitat of frogs is limited by shares Latin America, where the humidity est très high, around 80% warm. Most are Arboreal animals to climb trees with ease through their membership drives at the end of the fingers. Rarely go to pools of water, except for reproduction. Poison frogs lay their eggs in pools of warm water at the edge of the leaves where the eggs in a safe, high in the treetops.
There are 10 species of the genus Dendrobates. They are all bright colors: blue and Dendrobates azureus Dendrobates auratus IS, lives in Costa Rica, is green with black spots on a regular basis. A very small species Dendrobatespumilio-in fact, is only 1.8 cm long and is the smallest member of the family. The back is orange to bright red and has small dark spots, black tea tips.
There are several very highly toxic species of the genus Phyllobates. Terri Bilis dart, the most poisonous dart frog frogs is all belongs to this genus.
The poison frogs is a subject of scientific research. First, there are several species of snakes and frogs in South America That Feeds are not affected. For this, a question can arise as some animals resistant to batrachotoxin Be. In addition, allow scientists to examine the Strong Poison, such as nerve impulses are transmitted organisms in animals, and why not in human. Scientists have discovered that just do not block batrachotoxin the nervous system, at first, leading to strong contractions of the heart muscle. The researchers say the Pumiliotoxin of Dendrobates auratus Pub could be used as a heart stimulant after a heart attack. According to the National Institutes of Health offer, poison dart frogs, more than 300 components, chemical alkaloid similar to cocaine and morphine and may be used for medical purposes. Some drugs on the basis of batrachotoxin and used as an anesthetic in surgery.
