The most extreme cases of this belief is the well- - known fable of the "barnacle-geese," an illustrated account of which was printed in an early volume of the Royal Society of London.
A large species of barnacle, Balanus psittacus, is found in great abundance from Concepcion to Puerto Montt, and is not only eaten by the natives, by whom it is called Pico, but is also esteemed a great delicacy in the markets of Valparaiso and Santiago.
BARNACLE, a name applied to Crustacea of the division Cirripedia or Thyrostraca.
It was not till Vaughan Thompson demonstrated, in 1830, their development from a free-swimming and typically Crustacean larva that it came to be recognized that, in Huxley's graphic phrase, "a barnacle may be said to be a Crustacean fixed by its head and kicking the food into its mouth with its legs."
The vernacular name barnacle, traceable to the fable of pedunculate cirripedes hatching out into bernicle geese, has also been transferred to the sessile cirripedes, which are popularly known as acorn barnacles.
