Summary

[edit]
Description
Français :

Le bénitier commun (Tridacna Maxima), ou grand bénitier, est une espèce courante des récifs coralliens de la Mer Rouge, de l'Océan Indien et du Pacifique. Il est consommé par beaucoup de populations locales de ces océans, et même élevé artisanalement par endroits, notamment dans certains atolls des Tuamotu en Polynésie. Durant la journée, il laisse dépasser son épais manteau souvent très coloré (bleu, vert, violet...) pour assurer la photosynthèse de ses algues symbiotiques, qui contribuent à le nourrir ; il est cependant capable de le rétracter très rapidement et de se refermer d'un coup, brisant net tout objet qui pourrait se trouver entre ses deux solides valves réunies par un muscle extrêmement puissant.

English:

The common clam ( Tridacna Maxima ), or giant clam, is a common species of coral reefs in the Red Sea, the Indian Ocean and the Pacific. It is eaten by many local populations in these oceans, and even farmed artisanally in places, particularly in certain atolls of the Tuamotu in Polynesia. During the day, it lets its thick, often very colorful (blue, green, purple, etc.) mantle stick out to ensure the photosynthesis of its symbiotic algae, which contribute to feeding it; it is however capable of retracting it very quickly and closing suddenly, breaking any object that could be between its two solid valves joined by an extremely powerful muscle.
