LULS @ Wikipedia!

I was reading this awesome page on common misconceptions and witnessed the fallacy of an open Wiki page:

Biology

  • Warts on human skin are caused by viruses that are unique to humans (Human papillomavirus). Humans cannot catch warts from toads or other animals; the bumps on a toad are not warts.[68]
  • The claim[69] that a duck‘s quack does not echo is false, although the echo may be difficult to hear for humans under some circumstances.[70]
  • The notion that goldfish have a memory of only three seconds is completely false.[71][72] They have been trained to navigate mazes and can recognize their owners after an exposure of a few months.[73][74]
  • Lemmings do not engage in mass suicidal dives off cliffs when migrating. They will, however, occasionally, and unintentionally fall off cliffs when venturing into unknown territory, with no knowledge of the boundaries of the environment. The misconception is due largely to the Disney film White Wilderness, which shot many of the migration scenes (also staged by using multiple shots of different groups of lemmings) on a large, snow-covered turntable in a studio. Photographers later pushed the lemmings off a cliff.[75][76]
  • Bats are not blind. While most bat species do use echolocation to augment their vision, all bats have eyes and are capable of sight.[77][78][79]
  • Mammal blood is bright red or scarlet when oxygenated and a darker red when not oxygenated. It is never blue. Veins appear blue through the skin because of differential absorption of wavelengths of the blood’s color by the overlying skin and flesh.[80]
  • My balls are huge.
  • It’s a common myth that an earthworm become two worms when cut in half. This is not correct.[81] An earthworm can survive being bisected, but only the front half of the worm (where the mouth is located) can survive, while the other half dies.[82] On the other hand, species of the planaria family of flatworms actually do become two new planaria when bisected or split down the middle.[citation needed]
  • According to urban myth, the Daddy Long-Legs Spider (Pholcus phalangioides) is the most venomous spider in the world, but it is harmless to humans because its fangs cannot penetrate human skin. This is false as Pholcus phalangioides can pierce human skin, however, the toxicity of this spider’s venom has just a weak effect on insects, let alone humans.[83] In addition, there is also confusion regarding the use of the name “Daddy Long Legs”, because Harvestmen (order Opiliones, which are not spiders) and crane flies (which are insects) are also commonly referred to as Daddy Long Legs, and share (also incorrectly) the myth of venomousness.[84][85]
