Barnacles have two distinct larval stages, the nauplius and the cyprid, before developing into a mature adult. A fertilised egg hatches into a nauplius: This undergoes six moults, passing through five instars , before transforming into the cyprid stage.

Nauplii are typically initially brooded by the parent, and released after the first moult as larvae that swim freely using setae. The cyprid larva is the last larval stage before adulthood.

It is not a feeding stage; its role is to find a suitable place to settle, since the adults are sessile.

It explores potential surfaces with modified antennules ; once it has found a potentially suitable spot, it attaches head-first using its antennules and a secreted glycoproteinous substance.

Larvae assess surfaces based upon their surface texture, chemistry, relative wettability, color, and the presence or absence and composition of a surface biofilm ; swarming species are also more likely to attach near other barnacles.

It cements itself permanently to the substrate with another proteinaceous compound, and then undergoes metamorphosis into a juvenile barnacle.

Typical acorn barnacles develop six hard calcareous plates to surround and protect their bodies. For the rest of their lives, they are cemented to the substrate, using their feathery legs cirri to capture plankton.

Once metamorphosis is over and they have reached their adult form, barnacles continue to grow by adding new material to their heavily calcified plates.

These plates are not moulted ; however, like all ecdysozoans , the barnacle itself will still moult its cuticle. Most barnacles are hermaphroditic , although a few species are gonochoric or androdioecious.

The ovaries are located in the base or stalk, and may extend into the mantle, while the testes are towards the back of the head, often extending into the thorax.

Typically, recently moulted hermaphroditic individuals are receptive as females. Self-fertilization, although theoretically possible, has been experimentally shown to be rare in barnacles.

The sessile lifestyle of barnacles makes sexual reproduction difficult, as the organisms cannot leave their shells to mate. Barnacles probably have the largest penis to body size ratio of the animal kingdom.

Barnacles can also reproduce through a method called spermcasting, in which the male barnacle releases his sperm into the water and females pick it up and fertilise their eggs.

Most barnacles are suspension feeders; they dwell continually in their shells, which are usually constructed of six plates, [2] and reach into the water column with modified legs.

These feathery appendages beat rhythmically to draw plankton and detritus into the shell for consumption. Other members of the class have quite a different mode of life.

For example, members of the superorder Rhizocephala , including the genus Sacculina , are parasitic and live within crabs.

Since the intertidal zone periodically desiccates , barnacles are well adapted against water loss. Their calcite shells are impermeable, and they possess two plates which they can slide across their apertures when not feeding.

These plates also protect against predation. Barnacles are displaced by limpets and mussels , which compete for space. They also have numerous predators.

In the swamping strategy, vast numbers of barnacles settle in the same place at once, covering a large patch of substrate, allowing at least some to survive in the balance of probabilities.

Competitors may include other barnacles, and disputed evidence indicates balanoid barnacles competitively displaced chthalamoid barnacles. Balanoids gained their advantage over the chthalamoids in the Oligocene, when they evolved tubular skeletons, which provide better anchorage to the substrate, and allow them to grow faster, undercutting, crushing, and smothering the latter group.

Among the most common predators on barnacles are whelks. They are able to grind through the calcareous exoskeletons of barnacles and feed on the softer inside parts.

Mussels also prey on barnacle larvae. Barnacles and limpets compete for space in the intertidal zone. Underside of large Chesaconcavus sp.

Miocene showing internal plates in bioimmured smaller barnacles. The anatomy of parasitic barnacles is generally simpler than that of their free-living relatives.

They have no carapace or limbs, having only unsegmented sac-like bodies. Barnacles were originally classified by Linnaeus and Cuvier as Mollusca , but in John Vaughan Thompson published observations showing the metamorphosis of the nauplius and cypris larvae into adult barnacles, and noted how these larvae were similar to those of crustaceans.

In Hermann Burmeister published further information, reinterpreting these findings. The effect was to move barnacles from the phylum of Mollusca to Articulata , showing naturalists that detailed study was needed to reevaluate their taxonomy.

Charles Darwin took up this challenge in , and developed his initial interest into a major study published as a series of monographs in and Some authorities regard the Cirripedia as a full class or subclass , and the orders listed above are sometimes treated as superorders.

In , Martin and Davis placed Cirripedia as an infraclass of Thecostraca and divided it into six orders: Infraclass Cirripedia Burmeister , Trace fossils of acrothoracican barnacle borings Rogerella are common in the fossil record from the Devonian to the recent.

Barnacles can play an important role in estimating paleo-water depths. The degree of disarticluation of fossils suggests the distance they have been transported, and since many species have narrow ranges of water depths, it can be assumed that the animals lived in shallow water and broke up as they were washed down-slope.

The completeness of fossils, and nature of damage, can thus be used to constrain the tectonic history of regions.

Particularly in the case of ships, they are classified as fouling organisms. The stable isotope signals in the layers of barnacle shells can potentially be used as a forensic tracking method for whales , loggerhead turtles and marine debris , such as shipwrecks or a flaperon suspected to be from Malaysia Airlines Flight Some barnacles are considered edible by humans, including Japanese goose barnacles e.

Capitulum mitella , and goose barnacles e. Pollicipes pollicipes , a delicacy in Spain and Portugal. Indeed, the word "barnacle" originally referred to a species of goose, the barnacle goose Branta leucopsis , whose eggs and young were rarely seen by humans because it breeds in the remote Arctic.

Additionally, the picoroco barnacle is used in Chilean cuisine and is one of the ingredients in curanto. Barnacles slowly reclaim pilings along the Siuslaw River in Oregon.

Gooseneck barnacles being enjoyed in a Spanish restaurant in Madrid. From Wikipedia, the free encyclopedia. I have frequently seen, with my own eyes, more than a thousand of these small bodies of birds, hanging down on the sea-shore from one piece of timber, enclosed in their shells, and already formed.

They do not breed and lay eggs like other birds, nor do they ever hatch any eggs, nor do they seem to build nests in any corner of the earth.

However, it was also criticized by other medieval authors, including Albertus Magnus. This belief may be related to the fact that these geese were never seen in summer, when they were supposedly developing underwater they were actually breeding in remote Arctic regions in the form of barnacles —which came to have the name "barnacle" because of this legend.

Based on these legends—indeed, the legends may have been invented for this purpose [13] —some Irish clerics considered barnacle goose flesh to be acceptable fast day food, a practice that was criticized by Giraldus Cambrensis , a Welsh author:.

Bishops and religious men viri religiosi in some parts of Ireland do not scruple to dine off these birds at the time of fasting, because they are not flesh nor born of flesh But in so doing they are led into sin.

For if anyone were to eat of the leg of our first parent Adam although he was not born of flesh, that person could not be adjudged innocent of eating meat.

At the Fourth Council of the Lateran , Pope Innocent III explicitly prohibited the eating of these geese during Lent, arguing that despite their unusual reproduction, they lived and fed like ducks and so were of the same nature as other birds.

The question of the nature of barnacle geese also came up as a matter of Jewish dietary law in the Halakha , and Rabbeinu Tam —71 determined that they were kosher even if born of trees and should be slaughtered following the normal prescriptions for birds.
