Distribution and Ecology
Crangon crangon has a wide range, extending across the north-eastern Atlantic Ocean from the White Sea in the north of Russia to the coast of Morocco, including the Baltic Sea, as well as occurring throughout the Mediterranean and Black Seas. Despite its wide range, however, there is little gene flow across certain natural barriers, such as the Strait of Gibraltar or the Bosphorus. The populations in the western Mediterranean Sea are thought to be the oldest, with the species' spread across the north Atlantic thought to post-date the Pleistocene.
Adults live epibenthically (on or near the sea-floor) especially in the shallow waters of estuaries or near the coast. It is generally highly abundant, and has a significant effect on the ecosystems it lives in.

Famous quotes containing the words distribution and/or ecology:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
