> >The five most dangerous spiders on the planet
Spiders are not as scary as it may seem at first glance. They destroy insect pests, protecting the gardens and orchards. The unique properties of the web have been used in many industries and even in the military. However, among the spiders there are truly terrible creatures, a meeting with which can be fatal for humans.
Brazilian wandering spider
The Brazilian soldier spider, or Brazilian wandering spider, is a member of the genus Phoneutria, or spider runner, and, according to scientists, the most poisonous spider on Earth. Its bite can take an adult’s life in a few minutes. They live in the thickets of bananas, so they are also called banana spiders. They are quite large, the diameter of the body is about 5 centimeters, and the distance between the legs is 12-15 centimeters. They are brown with black spots on the abdomen. Insects are mainly active at night, although insect spiders do not disdain other spiders, small lizards, and mice. Feeling threatened, the spider lifts its legs high, trying to frighten the enemy.These spiders are considered very aggressive, however, according to scientists, they show aggression only if they consider that they are threatened or attacked.
The scientific name of this famous spider is Latrodectus mactans. It lives mainly in the southern United States, but from time to time it is found in most countries of the Western Hemisphere. In this species, females are much larger and heavier than males. Being 2-3 times larger than the partner, the female black widow easily kills him after mating. The poison of the black widow is 15 times stronger than the poison of a rattlesnake. The latrotoxin contained in it is the strongest neurotoxin that quickly causes vomiting, shortness of breath, delirium, loss of consciousness and paralysis.
Brown recluse spider
Brown hermit spiders are most common in the eastern United States, although they can be found in many countries in the Western Hemisphere. These are single spiders, but they prefer to settle not in deep forests and marshes, but in dark corners of closets, basements and cloakrooms in human habitation. A spider attempts to approach a person’s shelter as an attack and react accordingly. Symptoms of a bite include irritation and itching, fever, fever, nausea, ulcers at bite sites.
Sydney funnel spider
The habitat of the Sydney funnel spider corresponds to the name: these creatures live in the vicinity of Sydney and within a radius of 100 kilometers from it. The fungal spider neurotoxin is different in its action from the toxins of most spiders, intended to cause paralysis of the victim's nervous system. Atrakotoksin funnel spider acts differently. It dramatically increases blood pressure and causes millions of air bubbles to explode in the lungs. The man begins to choke, as if under water. Ironically, atrakotoksin is harmless to most mammals, but it is deadly for primates: an adult dies only 15 minutes after being bitten.
Red-backed spiders live in abundance in Australia, and there are many of them in New Zealand, Japan, and Southeast Asia as a whole. They received their name for the red spot on the back, because of which the red-spined spider is often confused with the black widow. They live in the vicinity of human habitation, climbing into such unexpected places as mailboxes, barns, and latrines. The poison contains a neurotoxin that causes vomiting, profuse sweating, headache, chest tightness, and general ill-being for at least 24 hours.In more severe cases, loss of consciousness, apnea and death occur.
