Ways to Generate Pearl Shellfish Shellfish include molluscs fillum into an animal triploblastik selomata are soft-bodied. To it, including all animals with or without shell software, such as various types of snails, Kiton, shellfish and squid.
This animal has a characteristic body is not segmented. Bilateral symmetry. Its body is made up of "foot" muscular, with a growing head varies by class. Feet are used in adapting to survive in the substrate, sanibel seashells the substrate sanibel seashells dig and drill, or perform movements. Pengahasil sanibel seashells known as pearl shells. sanibel seashells The process of making pearls 1. Shape engineering engineering is known as grafting or seeding or implantation as well, namely by inserting the core (nucleus) with a piece of mantle organs (another pearl oyster meat slices known as 'saibo') into the pearl oyster. Mantle organ is taken by another individual pearl oysters and act as donors. Based on research, the selection of good donor will determine the quality sanibel seashells of pearls produced mainly in terms of color, shape and luster of pearls. Core and mantle wedge is placed in the gonads shells having previously made a small incision in the gonad wall. Coat meat slices will form a pearl sac (pearl sac) and will produce nacre. This process is known as biomineralization, as well as the process of bone formation in humans and other vertebrates. Nacre is the lustrous surface of the pearl or the wall also sparkling in the shells. On the inside of the shells, nacre termed as Mother of Pearl (mother of pearl) while the nacre inherent in the core is called the pearl. The quality of the resulting nacre determines the overall quality of the pearls. The process of inserting a small part of a long series of breeding process since the determination of the location of cultivation until the post-harvest handling. The principle is based on the insertion process of how the formation of natural pearls which the shells will wrap unavoidable irritant with nacre. The working principle is the same when the mussel shells were damaged, they would immediately close the hole with nacre, thus preventing exposure of its body. However, so far there is no evidence that natural pearls are formed due to the inclusion of grains of sand into the body shells. Strong assumptions that support the formation of nacre layer is the presence of viruses sanibel seashells such as those found in several types of cultured pearl oysters.
2 Naturally In nature, pearls are formed due to the irritant into the mantle of pearl shells. Phenomena of this irritant is often interpreted by the entry of sand or solids into the mantle then this object will be wrapped so that the nacre pearls. The formation of natural pearls is divided into two major parts, formed by the irritant and the entry of solid particles in the mantle of mollusks. In principle, a pearl is formed by the epithelium of the mantle that goes into the mantle cavity. Part of the mantle epithelium is responsible for issuing sanibel seashells / mendeposisikan nacre on the inside of the mussel shells in addition to forming the entire shell. Theory irritant revealed that at some point the tip of the mantle of the clams are eaten by fish, this is possible because the shells will open a shell and stuck out his coat to absorb the food. When breaking up his coat, the crumb eptiheliumpun into the mantle cavity. Theory irritant could have also revealed that pearls are formed due to the entry of worms that usually occupy the mollusk in their development and then move on to other organisms. This worm damage and entering the mantle cavity. This worm accidentally bring the epithelium on the surface coat with him. When the worms die in the mantle cavity, then this worm will be wrapped sanibel seashells by the epithelium, forming a pearl sac and eventually forming a pearl. Even if the worm can escape, sanibel seashells then living in the cavity epithelium mantellah which will form the pearl sac after previously forming a pearl. While the latter theory is the inclusion of solid particles into the mantle cavity. Solid particles can be trapped in the body of water shellfish due impetus. When these shells can not remove it, even this particle could have entered into the mantle cavity. When he entered, epithelium also come with her. This epithelium eventually wrapped sanibel seashells solid particles forming a pearl sac. These pearl sacs eventually sanibel seashells be mendeposisikan nacre to such solid particles. However, so far there has been no scientific evidence to support the theory of the entry of sand into a pearl oyster mantle, although this theory has long understood. Of the few natural pearls are dissected, showing that the pearl is not a core part of solid particles.
