	CRUSTACEA - LoveToKnow Article on CRUSTACEA
		The most peculiar modification, perhaps, is that found in the Cirripedia (Thyrostraca), in the larvae of which the antennules develop irgo organs of attachment, bearing the openings of the cement-glands, and becoming, in the adult, involved in the attachment of the animal to its support.
		In the Cirripedia, however, they are vascular processes from the inner surface of the mantle or shell-fold, and in some Ostracoda they are outgrowths from the sides of the body.
		The barnacles and their allies, forming the group Cirripedia or Thyrostraca, sometimes treated as a separate sub-class, are distinguished by being sessile in the adult state, the larval antennules serving as organs of attachment, and the antennae being lost.

	BARNACLES: Class Cirripedia
		The Cirripedia belong to the class Maxillopoda, an ancient form of relatively small, primarily marine crustaceans which today, are presently known by 11 subclasses, five of which are completely parasitic.
		Out of the six nonparasitic subclasses, the Ostenocarida and Skaracarida are extinct, dating back to the Cambrian period, and the Mystacocarida are now generally restricted to a narrow band of the marine interstitial environment.
		On the other hand, of the primarily nonparasitic groups, the Ostracoda and Cirripedia (from Cambrian period) and Copepoda are very diverse and occupy a wide variety of aquatic habitats.

		If fossil cirripedia had, like most recent species, very wide horizontal or geographical ranges, then, in accordance with a law now generally admitted, a considerable vertical range in some of the species is not improbable.
		This is likewise the case with the Cirripedia, and it is only the wonderful elongation of the anterior part of the head, its fixed condition, and the absence of external eyes and antennæ, which gives to the Cirripedia their peculiar character, and has hitherto prevented the homologies of these parts from having been recognised.
		The cementing substance is brought to its point of debouchment by a duct, leading from a gland, which (and this is perhaps the most remarkable point in the natural history of the Class) is part of and continuous with the branching ovaria.

		This proposal, no doubt strengthened by his own widening interest and by Louis Agassiz's opinion that such a monograph was a "desideratum" (letter to J. Agassiz, 22 October 1848), was accepted by Darwin, and he immediately took steps to borrow as many collections of both fossil and recent specimens as possible.
		Darwin believed he had found a series of forms illustrating the gradual emergence of separate sexes in barnacles: Ibla quadrivalvis and Scalpellum vulgare represented a stage where the male organs were still present in the hermaphrodite but were superfluous and reduced owing to the presence of the minute "complemental" males, as Darwin called them.
		The sexual relations of barnacles seemed to him to mirror the probable emergence of dioecious plants from monoecious forms (Living Cirripedia (1851): 214; (1854): 29, 528 n.) and, at another level, to explain the existence of structures that properly belonged in only one of the sexes appearing as vestigial or rudimentary organs in the other.

		Nevertheless, his efforts were rewarded with the first public recognition of his scientific achievements when, in 1853, he was awarded a Royal Medal by the Royal Society of London for his contributions to geology and natural history, and in particular his Cirripedia work.
		The next two years were devoted to the anatomy and classification of sessile cirripedes and culminated in Living Cirripedia (1854) and Fossil Cirripedia (1854), again published by the Ray Society and the Palaeontographical Society.
		His work on the Cirripedia also brought prominently into view the occurrence of aberrance through the effects of extinction.

		I can, however, hardly persuade myself that the articulated membrane, under the free part of the mandibles, which has now been figured and described, has no homological signification; and the fusion of the palpus and labrum seems too plain to be mistaken.
		Hence I must conclude that the mouth, in the Cirripedia, does truly exhibit a compounded structure of a very peculiar nature.
		In Van de Hoeven's figure of the nervous system in Limulus, there is seen to be no chain of thoracic ganglions; all the nerves rising from the circa-oesophageal collar; but this, on the other hand, seems hardly developed into a ganglion.
