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 myths about what we’re supposed to feel as new mothers run strong and deep. . . . While joy and elation are surely present after a new baby has entered our lives, it is also within the realm of possibility that other feelings might crop up: neediness, fear, ambivalence, anger.”
—Sally Placksin (20th century)
“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)
“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)
