La fluorescence des coraux est due \u00e0 l’action d’une prot\u00e9ine appel\u00e9e\u00a0GPF pour green fluorescence protein.<\/p>\n

Cette prot\u00e9ine fluorescente a un r\u00f4le protecteur pour le corail face aux rayons nocifs du soleil, mais a \u00e9galement une application dans le ph\u00e9nom\u00e8ne de transformation de la lumi\u00e8re.<\/p>\n

les zooxanthelles contenues dans les tissus des coraux ont besoin d’un spectre lumineux bien sp\u00e9cifique pour se d\u00e9velopper et cro\u00eetre, cependant ces couleurs que sont le jaune et le rouge ne p\u00e9n\u00e8trent que tr\u00e8s faiblement dans l’eau et seuls le bleu et le vert ont une capacit\u00e9 de p\u00e9n\u00e9tration \u00e9lev\u00e9e.<\/p>\n

Le corail absorbe donc le bleu et le modifie enfin d’offrir du jaune de l’orange et du rouge aux zooxanthelles peuplant ces tissus.<\/p>\n

J’ai pris les deux photos ci-dessous lors de ma derni\u00e8re visite \u00e0 l’Aquarium des lagons<\/a> \u00e0 Noum\u00e9a.<\/p>\n<\/td>\n<\/tr>\n
