balanus Crustaceans, barnacles Division. Barnacle is attached to the seaside rocks clusters of gray, calcareous shell with small animals. Its shape a bit like a horse's teeth, so people often live in the sea called "horse teeth." Barnacles can not only attached to the reef, but also attached to the hull, despite the wind and waves have washed can not afford. Barnacle after peeling every time, we must secrete a viscous primary barnacle glue, this glue contains a variety of biochemical substances and strong adhesion to ensure its strong adsorption capacity. It is believed that frequent the beach will not be unfamiliar to the barnacle, right? Many people have seen, but it is not understood. Barnacles have a hard shell surface is often mistaken for shellfish, in fact it is arthropod crustaceans are spread foot target animals. Barnacle distribution of a wide, almost any area of intertidal zone to the shallow subtidal zone, its traces can be found; their myriad, often intensive live together, forming arthropods after the barnacle is the only line of sessile animals . Barnacles are hermaphroditic, the line cross-fertilization. Fixation because they can not move, in the reproductive period, to be able to rely on flexible thin tube, the manipulation of sperm into eggs fertilized barnacle else. To be fertilized eggs, after three or four months incubation; At this point, just hatched out of that small seedlings from the mother, but often must be floating a few weeks time, things can be attached to door. Ready to attach it, it will secrete a resin that can firmly adhere to their own hard object on. In many types of barnacle attachment, it will not have a specific place, from the coast of the rocks, docks, bottom, etc., where a hard object on the surface, are likely to be stuck with it, even in the whales, sea turtles, lobster, crab's body surface, are also often found attached barnacles. Type of barnacle beach cones individual small, but strong adhesive force, if you want hands on it uprooted from the attachment, it is almost impossible to be hard with a chisel like it knocked down the metal to . But also because it has a hard and strong adhesion of the shell, causing the shore playing in the water are often inadvertently damage.

Distribution
Barnacle distribution of a wide, almost any area of intertidal zone to the shallow subtidal zone, its traces can be found; their myriad, often intensive live together, forming arthropods after the barnacle is the only line of sessile animals . Barnacles usually live in deep sea areas, but occasionally can be washed from the seabed to the wreckage of the beach material was found.
