Misconceptions about lemmings go back many centuries. In the 1530s, the geographer Zeigler of Strasbourg proposed the theory that the creatures fell out of the sky during stormy weather (also featured in the folklore of the Inupiat/Yupik at Norton Sound), and then died suddenly when the grass grew in spring. This was refuted by the natural historian Ole Worm, who first published dissections of a lemming, and showed that lemmings are anatomically similar to most other rodents.

While many people believe that lemmings commit mass suicide when they migrate, this is not the case. Driven by strong biological urges, they will migrate in large groups when population density becomes too great. Lemmings can and do swim and may choose to cross a body of water in search of a new habitat. On occasion, and particularly in the case of the Norway lemmings in Scandinavia, large migrating groups will reach a cliff overlooking the ocean. They will stop until the urge to press on causes them to jump off the cliff and start swimming, sometimes to exhaustion and death. Lemmings are also often pushed into the sea as more and more lemmings arrive at the shore.

The myth of lemming mass suicide is long-standing and has been popularized by a number of factors. In 1955, Carl Barks...

...drew an Uncle Scrooge adventure comic with the title: The Lemming with the Locket. This comic, which was inspired by a 1954 National Geographic article, showed massive numbers of lemmings jumping over Norwegian cliffs. The suicide myth was further propagated by Walt Disney documentary White Wilderness in 1958 which includes footage of lemmings migrating and running head-long over a ledge.

An investigation in 1983 by the Canadian Broadcasting Corporation's Brian Vallee, showed that the Disney film makers faked the entire sequence using imported lemmings (bought from Inuit children), a snow covered turntable on which a few dozen lemmings were forced to run, and literally throwing lemmings into the sea to show the alleged suicides.
