C'est pas sorcier - Season 1 Episode 364 Les coraux : les sorciers cherchent la petite bête
Les coraux ne sont ni des végétaux, ni de simples cailloux décoratifs… mais de minuscules animaux - des polypes - qui, pour la plupart, vivent en colonies de milliers d'individus. Ces lointains cousins de l'anémone et de la méduse doivent leur survie à une association avec une micro-algue à laquelle ils offrent protection et nourriture, et qui en échange leur fournit les nutriments essentiels à leur survie. Que cette fragile petite algue disparaisse… et les coraux se mettent à dépérir. Fred et Jamy sont partie en Nouvelle-Calédonie pour découvrir avec nous l'étonnante biologie de ces mystérieuses petites bêtes marines. Mission Les coraux les plus connus sont les coraux constructeurs : de générations en générations, ils édifient un squelette externe qui finit par former une véritable muraille sous-marine. Mais il en existe beaucoup d'autres !
