 barnacle - HighBeam Encyclopedia   (Site not responding. Last check: 2007-11-01)
Barnacles are exclusively marine and are quite unlike any other crustacean because of the permanently attached, or sessile, mode of existence for which they are highly modified.
Barnacles with a calcareous shell (order Thoracica) include the gooseneck barnacles, which are attached to the substrate by means of a stalk, or peduncle, and the acorn, or rock, barnacles, which are attached directly to the substrate.
Barnacles are economically significant because they settle on ship hulls and harbor installations; the resulting encrustation of the ships greatly increases friction, diminishing speed and increasing fuel consumption.

 Barnacle (Half-Life) - Wikipedia, the free encyclopedia
Physically, barnacles resemble little more than a large mouth full of sharp teeth and a thin, but long and very powerful muscular hydrostat combining the functions of a tongue and tentacle, which can be retracted or extended to hang at near-floor level regardless of the animal's height from the floor.
Barnacles appear to be capable of killing and digesting a human being within only a few seconds, stripping the skeleton of flesh and spitting out indigestible bones.
As the barnacles are never seen moving, it can be assumed that their food requirements are relatively low and that they can survive for extended periods without food, perhaps explaining their sedentary lifestyle.

 barnacle - yourDictionary.com - American Heritage Dictionary
The barnacle goose breeds in the Arctic, a fact not known for a long time; since no one ever witnessed the bird breeding, it was thought to be spontaneously generated from trees along the shore, or from rotting wood.
Wood that has been in the ocean for any length of time is often dotted with barnacles, and it was natural for people to believe that the crustaceans were also engendered directly from the wood, like the geese.
This led one writer in 1678 to comment on the "multitudes of little Shells; having within them little Birds perfectly shap'd, supposed to be Barnacles [that is, barnacle geese]." In popular conception the two creatures were thus closely linked.
