Snakes or snakes are strictly carnivorous animals and although many people are afraid of them, they are animals that deserve to be preserved and respected, both because of its importance in the environment, but also because some species have medical importance. An example of this is jararaca venom, which alone is used in the pharmaceutical industry for the development of an important remedy for the control of hypertension, and for the manufacture of surgical glue.
Furthermore, the study of their poisons helps doctors to develop better and better antidotes. Stay here at PeritoAnimal and discover the most venomous snakes in Brazil.
Types of Harmless Snakes
Harmless snakes are those that are not poisonous, that is, they do not have venom. Some species can even produce venom, but they do not have the specific fangs to inoculate their victims with venom. These types of harmless snakes have the following characteristics:
- Rounded head.
- Round pupils.
- They do not have a loreal pit.
- Adults can reach several meters in length.
In Brazil, the main harmless and non-venomous snakes are:
boa constrictor
In Brazil there are only two subspecies, the good constrictor constrictor and the good amaralis constrictor, and both can reach up to 4 meters in length and have nocturnal habits. They prefer treetops, often traveling through the dry leaves of the ground to another territory in search of food. As they do not have venom, it kills the prey by wrapping its body on it, compressing it and suffocating it, hence its characteristic name, and because of that its body is cylindrical with a strong constricting musculature, and with a thinner tail.
Due to its temperament sometimes considered docile and non-aggressive, the boa constrictor has become popular as a pet.
anaconda
It is the second largest snake in the world, can live for up to 30 years and reach up to 11 meters, and there are reports throughout history of anacondas measuring 12 and 13 meters in length that can swallow a human being. Many myths revolve around the anaconda, see here in another article by PeritoAnimal, the 4 species of Anaconda, popular name that made this animal famous in movie theaters. The preferred habitat of this snake is the banks of lakes, streams and freshwater rivers, where it waits for a prey to appear to take water, its victims include frogs, toads, birds, other reptiles and small mammals.
canine
It is found in the northern territory of Brazil and in the Amazon rainforest and despite its black to yellow coloration, which could indicate that it is a venomous snake, the Caninana has no venom. However, it is a very territorial snake and that is why it can become quite aggressive. It can reach up to 4 meters.
fake choir
In Brazil, we have a variety of coral called False Coral, of the species oxirhopus guibei. It is a very common snake in the vicinity of São Paulo, and has a color that is very similar to a coral, but this particular species does not have venom inoculation fangs, therefore, they are harmless.
Python
Belonging to the group of constrictor snakes, it has a more prominent coloration of green, and can reach up to 6 meters in length. And although they don't have the tusks to inoculate venom, their teeth are large and curved inward.
venomous snakes from Brazil
Poisonous snakes have the characteristics of elliptical pupils and more triangular head, as well as the loreal pit and fangs capable of inoculating large amounts of venom into their victims. Some species have diurnal habits and others nocturnal, but if they feel threatened, even a species of nocturnal habit can move during the day to find another territory.
The Brazilian fauna holds a huge variety of snakes, and among the venomous snakes that live in Brazil, we can find the most diverse types of poisons, with different toxic actions. Therefore, if a snake accident occurs, it is important to know which species of snake caused the accident so that doctors can know the correct antidote.
Largest venomous snakes in Brazil
At largest venomous snakes that can be found in Brazil are:
true choir
One of the most venomous snakes in the world, in Brazil, it receives its name due to its great resemblance to false coral, which is not venomous. Its venom is capable of causing breathing difficulty and can kill an adult in a few hours. It has a very characteristic coloration in red, black and white and it is not possible to differentiate a false coral from a real one just by the arrangement of the colors, since the only way to differentiate the two is through the tusks, loreal pit and head, which can be quite difficult for a layman, so if in doubt keep your distance.
Rattlesnake
Known for the rattle on its tail that produces a very characteristic sound when this snake feels threatened, reaching up to 2 meters in length. Its venom is capable of causing muscle paralysis, and can be lethal because it is hemotoxic, that is, it causes blood clotting, affecting blood circulation to the heart.
Jaca pico de jackass
It is considered the most venomous snake in South America and one of the most venomous in the world. Its coloration is brown with dark brown diamonds, and it can reach up to 5 meters in length. Its neurotoxic venom can cause low blood pressure, altered heartbeat, bleeding due to the toxin's anticoagulant properties, diarrhea, vomiting, necrosis and kidney failure, leaving sequelae if the victim is rescued.
Jararaca
The name of this Brazilian venomous snake is well known to people who live in the interior and fishermen. It has a thin, brownish body and darker triangular spots all over the body, camouflaging well between dry leaves on the ground. Its venom can cause limb necrosis, low blood pressure, blood loss due to anticoagulant action, kidney failure and cerebral bleeding, causing the individual's death.
