Myths
- There is a popular myth that lemmings commit mass suicide by swarming off cliffs when they migrate. Driven by strong biological urges, some species of lemmings may migrate in large groups when population density becomes too great. Lemmings can swim and may choose to cross a body of water in search of a new habitat. In such cases, many may drown if the body of water is so wide as to stretch their physical capability to the limit. This fact combined with an unexplained fluctuations in the population of Norwegian lemmings gave rise to the myth.
- Piranha have a reputation as fearless fish that swarm in ferocious and predatory packs. However, recent research, which started "with the premise that they school as a means of cooperative hunting", discovered that they were in fact rather fearful fish, like other fish, who schooled for protection from their predators, such as cormorants, caimans and dolphins. Piranhas are "basically like regular fish with large teeth".

Famous quotes containing the word myths:
“In New York—whose subway trains in particular have been “tattooed” with a brio and an energy to put our own rude practitioners to shame—not an inch of free space is spared except that of advertisements.... Even the most chronically dispossessed appear prepared to endorse the legitimacy of the “haves.””
—Gilbert Adair, British author, critic. “Cleaning and Cleansing,” Myths and Memories (1986)
“... suffering does not ennoble. It destroys. To resist destruction, self-hatred, or lifelong hopelessness, we have to throw off the conditioning of being despised, the fear of becoming the they that is talked about so dismissively, to refuse lying myths and easy moralities, to see ourselves as human, flawed, and extraordinary. All of us—extraordinary.”
—Dorothy Allison (b. 1949)
“The myths have always condemned those who “looked back.” Condemned them, whatever the paradise may have been which they were leaving. Hence this shadow over each departure from your decision.”
—Dag Hammarskjöld (1905–1961)
