A ostra lança uma substância no invasor composta de 90% de aragonita (CaCO3), um material calcário, 6% de conqueolina (principal componente da parte externa da concha) 3 4% de água. O material é depositado sobre o invasor e cristaliza-se rapidamente. Normalmente cada ostra produz apenas 1 pérola, que leva cerca de 3 anos para ficar madura e que nem sempre é perfeitamente esférica (numa proporção de 1 a cada 10.000 animais, por isso é tão valiosa). Mas japoneses inventaram uma maneira de cultivar pérolas. Este vídeo mostra uma concha chinesa que foi cultivada de forma a produzir várias pérolas. ================== ENGLISH: The pearl, the only animal gemstone, is the result of the oyster protection against foreign invaders. The oyster releases a substance into the attacker composed of 90% of aragonite (CaCO3), a calcareous material, 6% of conqueolina (main component of the outer shell) and 4% of water. The material is deposited on the invader and crystallized quickly. Normally each oyster produces only one pearl, which takes about 3 years to mature and that is not always perfectly spherical (a ratio of 1 to 10,000 animals, that's why it is so valuable). But Japanese invented a way to cultivate pearls. This video shows a Chinese shell that was cultivated in order to produce various pearls. ===================== Texto adaptado de http://mundoestranho.abril.com.br/materia/como-a-ostra-produz-a-perola Vídeo da concha extraído de http://www.youtube.com/watch?v=Kb4lNPj2iFk Música extraíde de http://incomptech.com - "Lonely Harvest" CIÊNCIAS GERAIS - ParaMaker
