Are there poisonous toads in Brazil?
In the Brazilian fauna we can find several poisonous and dangerous animals, be they spiders , snakes and even frogs! You may have never imagined that an animal of these may not be harmless, but the truth is that they can be dangerous and there are poisonous toads in Brazil !
Types of poisonous toads
Frogs, as well as frogs and frogs, are part of the anurans family , a group of amphibians distinguished by the absence of a tail. There are more than 3000 species of these animals around the world, and in Brazil alone, you can find 600 of them.
Many people feel disgusted by their elastic skin and by the way the chin moves when they croak, but it is important to remember that they are essential for the balance of nature: with an insect-based diet, frogs help control the excess of flies and mosquitoes.
The main difference between frogs and frogs , as well as frogs, is that they have drier, less lustrous skin, in addition to being more dull. The similarity between the latter two is greater, however, the frogs have the ability to jump and climb trees and tall plants.
These anurans have sticky tongue, so when you see an insect approaching, it’s just projecting the body and sticking out its tongue, sticking its food and pulling it back. Its reproduction occurs through eggs that are deposited in outdoor environments. In general, frogs are harmless and pose no danger to humans. But, some groups, characterized by their flashy colors, as if they had been painted by hand, contain alkaloids in the skin .
These substances are obtained from feeding frogs, which eat mites, ants and plants that already contain alkaloids. Despite their toxic properties, the alkaloids present in frogs’ skin have been studied for the production of drugs capable of treating various diseases.
Within this family, there are several types of poisonous frogs that you should know about.
The most poisonous frog in the world
At only 2.5 centimeters, the little golden poison dart frog ( Phyllobates terribilis ) is not only the most poisonous frog in the world , but also appears on the list of most dangerous land animals. His body bears an extremely lively and lustrous yellow shade, which in nature is a clear sign of “danger, do not approach.”
This species belongs to the genus Phyllobates , understood by the family Dendrobatidae , cradle of the dangerous frogs that we see there. But remember none of them compare to our little golden frog. Less than a gram of its venom is enough to kill an elephant or an adult human. The toxin spread through your skin is able, from a simple touch, to paralyze the nervous system of the victim , making it impossible to transmit nerve impulses and move the musculature. These factors lead to heart failure and muscle fibrillation in instants.
Originating in Colombia, its natural habitat is temperate and fairly humid forests, with temperatures around 25 ° C. This frog was called “venomous darts” because the Indians used their poison to cover the tip of their arrows when they went out to hunt.
The story is a bit scary, but we must not forget that the golden frog will not use its poison against us if we cross it in a wood. The toxins are released only in extreme danger, as a defensive method. That is: just do not mess with her, she does not mess with you.
Poisonous Toads not Brazil
There are about 180 species of dendrobatidae spread throughout the world and currently there is a knowledge of at least 26 of them in Brazil , mainly concentrated in the region comprising the Amazon rainforest .
Several experts say there is no incidence of frogs of the genus Phyllobates in the country. However, we have amphibians from the Dendrobates group which, because they belong to the same family, carry similar characteristics, such as preference for temperate forests, humid climate and terrestrial fields, but above all, it is necessary to explain that Dendrobates are as poisonous as some of his cousins that we find in other regions.
This genus comprises a special group of thrush, known as an arrowhead , since they were also used by the Indians in coating their weapons. The main characteristics of the animals that integrate this group is the intense color of their skin, a sign silencing the poison they carry. Although not comparable to the golden poison dart frog , these frogs can be lethal if their toxins come in contact with some bruise on the skin of those who handle it, reaching the person’s bloodstream. However, their poison would hardly be fatal, unless they are swallowed up by some predator, wow!
Many of the frogs we found among the arrowheads were recently discovered and so it is still very difficult to distinguish them here in Brazil. Although they have their specific scientific names, they end up coming to popular knowledge as if they were only one species, due to their similar characteristics.
