生物珊瑚 通常被稱為珊瑚的材料實際上是骨骼,或者更確切地說,腳手架或多或少支,其中非常小的息肉(家庭腔腸動物)菌落他們在社區生活中產生。 實際上,單個息肉是在通過微觀通道哪個蜂窩珊瑚相互連續的通信,並且這也構成的市售產品中的主要特色之一。 提供了理想的環境是由具有18度和20度之間的溫度海域,具有深度範圍10到100米之間。必要條件,但是,是不存在的污染物,相對高的鹽度和可觀的亮度。 這解釋了地中海的重要性,特別是撒丁島,西西里海域,也北非,不僅在數量,而且還特別為產品的質量。而且,每一個規則都有其例外,它應該記住,他們在近1500米的深度採集珊瑚,大約有7溫度C. 珊瑚的生命週期發生在18/20年內,它必須有所收穫期:這個時期後,在降低一個廢棄的房子,碳酸鈣構成以同樣的方式珊瑚開始經受崩解的處理,加上特定的害蟲的作用加快。 對於原因還不得而知,可能會發生息肉,殖民地,也許一個廣泛的板凳corallifero的全部人口消失,海洋生物學家仍然在學習的原因意圖。 在過去,這樣的現象發生了令人印象深刻的方式夏卡,西西里島,在那裡埋在泥中發現一個重要的珊瑚化石存款,特點黃/橙色的海洋。

BIOLOGY OF CORAL The material commonly called coral is actually the skeleton, or rather the scaffolding more or less branched, which colonies of very small polyps (the family of coelenterates) produce during their life in the community. In fact, the individual polyps are in continuous communication with each other through the microscopic channels which honeycomb coral, and which also constitute one of the main distinctive features in the product marketed. The ideal environment is made up of seas with temperatures between 18 and 20 degrees, with depths ranging between 10 and 100 meters. essential conditions, however, are the absence of pollutants, a relatively high salinity and an appreciable brightness. This explains the importance of the Mediterranean, in particular of Sardinian, Sicilian waters, but also North African, not only in quantity, but also and especially for the quality of the product. And, as every rule has its exceptions, it should be remembered that they were collected corals at depths close to 1,500 meters, with temperatures around 7 C. The life cycle of corals takes place over 18/20 years, the period within which it must be harvested: after this period, in the same way that deteriorates an abandoned house, the calcium carbonate that make up the coral begins to undergo a process of disintegration, plus expedited by the action of specific pests. For reasons still unknown, it may happen that a colony of polyps, maybe the entire population of an extensive bench corallifero disappears, and marine biologists are still intent on studying the causes. In the past, such a phenomenon occurred in impressive way in the sea of Sciacca, Sicily, where buried in the mud was discovered an important fossil coral deposits, the characteristic yellow / orange color. |
