Variations of Bristle in The Animal Kingdom
Bristles are found on pig breeds instead of fur on most mammals. Because the density is less than with fur, pigs are vulnerable to sunburn. One breed, the Tamworth Pig is endowed with a very dense bristle structure such that sunburn damage to skin is minimized. Animals named for their bristles include bristlebirds, the Bristle-thighed Curlew, the Bristle-spined Porcupine, and the Trinity bristle snail. Bristles also anchor worms to the soil to help the worm move.

Famous quotes containing the words variations, animal and/or kingdom:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
“‘Tis said that courage is common, but the immense esteem in which it is held proves it to be rare. Animal resistance, the instinct of the male animal when cornered, is no doubt common; but the pure article, courage with eyes, courage with conduct, self-possession at the cannon’s mouth, cheerfulness in lonely adherence to the right, is the endowment of elevated characters.”
—Ralph Waldo Emerson (1803–1882)
“A box of teak, a box of sandalwood,
A brass-ringed spyglass in a case,
A coin, leaf-thin with many polishings,
Last kingdom of a gold forgotten face,
These lie about the room....”
—Philip Larkin (1922–1986)
