The Marine lab on Aitutaki is housing a multitude of giant clams, while doing research on the impacts of amino acids in their survival. With the addition of these acids to their diets, the clams were found to survive longer and thrive better in their environment. In the wild, these clams are unlikely to survive past the first three days, with almost 99% not surviving past the first 24 hours of life.    
   
Their amazing colors are because of a phenotype variation, just like that of eye color in humans.
