The Black Widow is a very poisonous spider , but strangely shy. After studying for months at his home in Virginia, the naturalist Jack Landers had the opportunity to experience first row the annoying symptoms of the bite of an addition to test a new experimental treatment.
Landers says that despite his reputation , especially black widows are shy : Landers found near his home was a place to find , catch some and observe their habits closely. By feeding them crickets or other small insects , Landers noted that the first instinct is to retreat , when they attack , involving only its prey and inject venom end . Females are much more colorful and poisonous than males : they are larger in size and have the characteristic red mark shaped hourglass, while the male is smaller and brown. Despite its name , the female rarely kills the male , and Landers believes only in captivity.
When a fishing trip , Landers was bitten by a black widow got into his shoe . The writer describes the symptoms as a " heat " up by deep abdomen during the first few minutes , followed by a feeling of tightness in the chest . When he reached the hospital, the doctors explained that antivenoms are used only when the patient is on the threshold of death , as these can cause allergic reactions .
The first antivenom for spider was discovered in 1895 by French physician Albert Calmette , who synthesized by injecting a horse with the spider toxin , causing your body to produce the antidote through the blood. Although the antidote has saved many lives , some people may be allergic to horse proteins , which can generate more dangerous reaction in the body that produced by black widow bite .
Landers , however , was part of a test group for a new antidote protein made with sheep instead of horse and as he told the New York Times, could return home without complications the next morning .
