Spiders have a strange fascination, from miniature reddish money spiders into giant tarantulas and deadly Black Widows. It can be said that no additional"insect" generates as much fear as the spider, also known as the 8-Legged Nightmare by a few.

Widow Spiders
Widow spiders contains 32 recognized species spread globally, including the North American black widows, the button spiders of Africa and the Australian redback. Individual species vary widely in size, but in the majority of cases the females are dark-colored and readily identifiable by red hourglass-shaped markings on the abdomen. The venomous sting of those spiders is considered particularly dangerous because of the neurotoxin latrotoxin, which causes the illness latrodectism, both named for its genus.

The female black widow has unusually large venom glands and her sting can be particularly harmful to humans. However, regardless of the genus, widow spider bites are rarely fatal. On account of the existence of latrotoxin within their own venom, black widow bites are potentially dangerous and may lead to systemic effects such as severe muscular pain, abdominal cramps, hyperhidrosis, tachycardia and muscular spasms. Symptoms usually last for 3 weeks --7 days, but may persist for several weeks.

The venom is identical in male and female spiders, however, females can have almost double the concentration of toxins. Recluse bites can cause necrosis in humans, rabbits and guinea pigs, but not in mice or rats.
