Formation of Pearls _ Where do Snails hide their bodies?..

Friends, we all like to wear ornaments embedded with precious stones. One of the precious stones is a pearl. Do you know how a pearl is formed? A natural pearl is formed. Pearls are of two categories, natural pearls and artificial pearls also. Actually, a natural pearl is formed in the body of oyster or snail. Suppose, if they eat food, sometimes even sand particles may enter their bodies. Sand particles or any foreign bodies enter their bodies. Whenever they enter their bodies, in order to protect themselves, they secrete some glittering juices around them, one after the other. Those are formed in the form of layers. Slowly, they thickened and glittered. So, in that way, a pearl is formed and it takes years together to make pearls. Every aspect in nature exhibits some variation. Some animals live in water, some animals live on land, some animals move horizontally to the earth, some move vertically to the earth like all human beings and all homo sapiens and all these. They exhibit variation. That is the wonderful creation of God. Based on structures, their habits, their characters, animals are categorized into different phylums. One of the phylums is mollusca. In this phylum, all animals have very delicate bodies. They hide their bodies in shell-like structures. Those are called mantle cavities. Whenever we go to beach or walk on the banks of the river, we like to collect these shells, right? So, these are the shells of those delicate bodies of molluscan species. Animals like snails, oysters come under this phylum mollusca. All these are the marvels of nature. Really wonderful. God's creation is simply... ...wonderful.
