Phoneutria species
(meaning killer in Greek) according to scientific principles, it includes 8 types of similar spiders, the legs of the Brazilian wandering spider can grow up to 10-13 cm and its body size is about 17-48 mm. This species is distinct from other species such as C. tenus…but it is easily confused with Kopie Cenus species, especially because they have red hair
At night, the Brazilian spider wanders on the forest floor more than staying in the nest, and during the day, it hides inside termite mounds, logs or boulders, as well as under bananas in gardens, hence they are called wanderers. Sometimes they are also found in dark and humid places near the places where people live, the Pingeunter species is more common in the dry season from April to June compared to other species. They have a specific defense mode, which is lifting and verticalizing the body. At first, it is to raise the 2 front legs and show the black designs under the body, and if the animal moves to and fro
Locations
This spider is found throughout the forests with rib trees (bananas, coconuts, etc.) in South America, east of the Andes to northern Argentina, in addition to Colombia, Venezuela, Guinness, Ecuador, Peru, Bolivia, Brazil and Paraguay. two species P. reidyi and P. boliviensis
They live from South Central America to the Amazon region. and a P. fera species
It is unique to the Amazon, the rest of the species also exist in the Atlantic region of Argentina. Only in the northeastern part of Brazil and in the north of Salvador and Bahia, this type of spider does not exist. In those areas, there is an educational program for children and students to know and how to deal with these spiders
Danger to humans
Brazilian spider venom is very deadly and is one of the few species that can harm humans and other animals. This species is infamous for two reasons: firstly, the poisonousness of the gas and secondly, the tendency to attack any creature that appears as a threat. Out of the eight species, Pi Negrionter and Pi Fara cause the most poisoning in venom bites. Pnegrionter is responsible for the most poisonings in Brazil because it is usually found in the densely populated areas of the southeast
New research has shown that these spiders inject a third of their venom in each bite, although research on this species is very difficult
Its bite may cause two tiny painful holes or a large poisonous welt! But in all cases persons who are Ctenid by P. Nigrionter or any kind of Ctenid
Those bitten should seek emergency treatment immediately, because the venom can be fatal. Due to the concentration of serotonin in the venom of killer spider species, they have a very painful and threatening sting
Also, their wandering nature is another reason why they are more dangerous, in crowded places they look for dark places to hide during the day. such as the dark corners of houses, clothes, cars or shoelaces or inside shoes or boxes, etc., in this way, people suddenly put the animal under an unknown threat and they themselves get bitten, another name for it is the banana spider because sometimes There are banana shipments
Despite their world fame, how their venom affects the human body is still being researched, one study says that only 2.3% of bites (mostly in children) were serious enough to require antivenom, however other scientific sources He points out that they are dangerous and poisonous and researches about their toxicology. One of the important sources that have been offered to people about toxicology is the book “Poisonous animals and their poisons”

by Wolfgang Bucheral and Eleanor Buckley
It has been written and in an experiment, they have proven that only 6 thousandths of a milligram of this spider’s venom is enough to kill a 20-gram pet mouse. And he also compared it with black widow poison. An investigation also tells about the death of two children by a killer spider in Sao Sebastiao
Pharmaceutical science also emphasizes the threat and danger of killer spider venom and says that they are the most poisonous and dangerous spider in the world
