It has a flat appearance, so it is associated with a crab. But they don´t attack any human being, for they even fear him; only in case of defense, though its name means: murderous spider. But if it were to do so, it has been proven that its venom is lethal and there is no kind of antidote, until the date discovered.
Recluse or violinist spider (Loxosceles)

It belongs to the genus “Latrodectus”, which register 31 accepted species and this is the best known. Her way of reproducing is very violent, because after mating, the female proceeds to eat the male, so she is called a black widow. Its venom is deadly and completely paralyzes the central nervous system, as well as producing in some cases intense erections in men. Fortunately, you do have the antidote.
From the Hadronyche family, from Australia. Females are larger than males and reach 8 centimeters.
