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:
“The poets were not alone in sanctioning myths, for long before the poets the states and the lawmakers had sanctioned them as a useful expedient.... They needed to control the people by superstitious fears, and these cannot be aroused without myths and marvels.”
—Strabo (c. 58 B.C.–c. 24 A.D., Greek geographer. Geographia, bk. 1, sct. 2, subsct. 8.
“Two myths must be shattered: that of the evil stepparent . . . and the myth of instant love, which places unrealistic demands on all members of the blended family. . . . Between the two opposing myths lies reality. The recognition of reality is, I believe, the most important step toward the building of a successful second family.”
—Claire Berman (20th century)
“What passes for identity in America is a series of myths about one’s heroic ancestors. It’s astounding to me, for example, that so many people really seem to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldn’t stay there any longer and had to go someplace else to make it. They were hungry, they were poor, they were convicts.”
—James Baldwin (1924–1987)
