Sound Production in Mating Rituals
Males of Heteropoda venatoria, one of the huntsman spiders that seems to easily find its way around the world, have recently been found to deliberately make a substrate-borne sound when they detect a chemical (pheromone) left by a nearby female of their species. The males anchor themselves firmly to the surface onto which they have crawled and then use their legs to transmit vibrations from their bodies to the surface. Most of the sound emitted is produced by strong vibrations of the abdomen. The characteristic frequency of vibration and the pattern of bursts of sound identify them to females of their species, who will approach if they are interested in mating.

Famous quotes containing the words sound, production, mating and/or rituals:
“There have been many stories told about the bottom, or rather no bottom, of this pond, which certainly had no foundation for themselves. It is remarkable how long men will believe in the bottomlessness of a pond without taking the trouble to sound it.”
—Henry David Thoreau (1817–1862)
“The repossession by women of our bodies will bring far more essential change to human society than the seizing of the means of production by workers.”
—Adrienne Rich (b. 1929)
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“Liberation is an evershifting horizon, a total ideology that can never fulfill its promises.... It has the therapeutic quality of providing emotionally charged rituals of solidarity in hatred—it is the amphetamine of its believers.”
—Arianna Stassinopoulos (b. 1950)
