Bigfoot

Whether you call it Bigfoot, Sasquatch or Yeti, this ape-like cryptid has eluded science since -- well, since science began trying to confirm its existence.

As with most cryptids, the legend goes back centuries to native populations who told stories of large, ape-like creatures wandering the woods. For primatologists such as the very famous Dr. Jane Goodall, these accounts are proof enough.

But scientific belief in Bigfoot has suffered from notable hoaxes, from fake casts of giant feet to doctored videos. Most recently, in 2008, the "body" of a supposed Sasquatch was found to be nothing more than faux fur and rubber feet.

If Bigfoot does exist, sightings suggest that the creature would weigh several hundred pounds and be between 6 feet and 10 feet tall.

And, regardless of whether or not this cryptid exists, there's no denying the loyal following, fan base and flat-out believers who have devoted their lives and research to Bigfoot.
