Barnacles appear more mineral than animals, and anyone who has no experience with marine life will see it as a mystery. Most people do not understand what exactly barnacles are, even those who have encountered them frequently. Barnacles can be classified as arthropods or they can be referred to as invertebrate animals having an exoskeleton. As we all know that invertebrates are made up of a large family of animals comprising of over 1 million subspecies, we have anthropoids as one of the members.
The anthropoid family includes spiders, scorpions, crabs among other minor species. Barnacles belong to curl-footed families close to shrimps, calling crabs, lobsters among others. Barnacles reproduce through interchanging between the female and male reproductive organs during reproduction. The reproduction in this animal creature can happen in either of two commonly known ways.
It can be accomplished by its long extraordinary penis or sperms that can be cast into the water to fertilize the female pickups. After fertilization, the development of the embryo begins to grow. At a given lava stage, the culprit attaches itself to the older ones or look for a comfortable place to thrive for good. Barnacles live mostly in salty water, and they like finding their homes on firm ground, attached to objects such as boats, stones, or other animals like whales, just to get a firm and clean place with enough nutrients or any comfortable place.
After settling, they will attach a begin releasing body fat which acts as a sterilizing agent, obstruction while removing body system dirt. The barnacle releases a natural glue that attracts and accumulates limestone salt to form a strong barnacle shell.
This clue is made up of six natural proteins from the barnacle. Thus clue is a very strong clue that is six times stronger than any other strong generic glue. The research has been done on how this clue can be extracted so that it can be applied to industries for the manufacture of useful glue for engineering fields.
Barnacles are filter organisms that feed mostly on planktons while dissolving detritus suspended in water. Barnacles have eaten in some countries such as Portugal and Spain among other European.
Its fleshy stem is known to be a very delicious meal that normally ends up on the plate in most countries around north America. You can simply scrub a goose binnacle clean and steam over broth of herbs and wine, then you peel off the stem and eat it in a soup and the entire body is discarded.
When underwater, acorn barnacles consume zooplankton. The filter feeding crustaceans also eat a lot of detritus. In the cold winter months, acorn barnacles abstain from eating, depending entirely on previously saved sustenance supplies. They also occasionally consume waste matter from fish. Acorn barnacles utilize their "cirri" for feeding purposes. Cirri are also used for breathing. Acorn barnacles are largely inactive beings. The bulk of the organisms' activity typically consists of mating and vying for precious "real estate" in shore settings, whether over a large rock or on a boulder or wharf.

Barnacles are eaten mainly in Spain and Portugal but also end up on the plate in other European countries and are increasingly eaten in North America Only the fleshy stems of Goose Barnacle are edible. Barnacle gathering on the West Coast of Canada has been reopened after a 4 year halt to establish environmental controls. A commercial license is required for gathering and or posession in the U. Gathering edible barnacles is difficult and dangerous.
Every year people die gathering them along the Iberian peninsula in Europe and the Pacific Northwest coast of North America. Experimental commercial aquaculture is being established in the Pacific Northwest to meet increasing demand. Barnacles first appear in the Middle Cambrian about million years ago but had not yet developed the hard calcareous outer shell we see today. They are Crustaceans, thus related to shrimp but not too closely with which they share the basic crustacean anatomy.
Ottawa: National Museums of Canada; Barnacles are a type of sedentary crustaceans, including around 1, species worldwide. In North America, barnacles include one species of stalked barnacle along the Pacific coast, the gooseneck barnacle Pollicipes polymerus , and four species of cemented acorn barnacles, two along the Pacific coast, the thatched barnacle Semibalanus cariosus and Balanus glandula , and two along the Atlantic coast, the rock barnacle Semibalanus balanoides and the ivory barnacle Balanus eburneus.
Barnacles are very distinct from other crustaceans like crabs, lobsters, and shrimps. They secrete a calcareous shell resembling that of bivalve mollusks, like clams, cockles, mussels, oysters, and scallops. Their head is reduced, their abdomen is absent, and their six pairs of legs are long and curved, often protruding outside the shell to filter-feed or trap animal preys.
Barnacles are permanently attached to the substrate, either hanging down by a stalk, often from floating logs, in stalked barnacles or cementing their shell directly onto the substrate in cemented acorn barnacles. Barnacles tend to be found in shallow and tidal waters, but they can colonize in great numbers almost any substrate, from living animals, like crabs or whales, to artificial objects, like boat bottoms.
They are hermaphrodites and usually reproduce by cross-fertilization between neighbours. Fertilized eggs are stored within the shell until larvae are released and go through series of free-swimming larval stages before settling into a sessile juvenile barnacle.
Barnacles, like other filter-feeders, can accumulate bacterial or viral agents, pollutants, or biotoxin that can be harmful to humans.
