The black widow spider (Latrodectus mactans) is one of the most famous and dangerous spiders in the world. This small creature has a powerful venom that is 15 times stronger than that of a rattlesnake. Although fatalities from its bite are rare, severe pain, muscle spasms, and nervous system disorders are the main consequences of its attack.
The spider got its ominous name because of its cannibalism: the female often eats the male after mating. The black widow lives in warm regions of America, Africa, Europe, Asia and Australia.
