New giant clam species was discovered by researchers at the University of Queensland in coral reefs in Western Australia and in the Solomon Islands. The most famous are the giant clams of the genus Tridacna, which reach 230 pounds and are easily distinguished due to the coral reefs of the colored, photosynthetic mantle. In the adult phase of these bivalve molluscs are not moved, but their genes are transferred from one population to another through the eggs, sperm and larvae that drift in the water.

Studying the gene flow of different clams Tridacna maxima in the eastern Indian and western Pacific Ocean, scientists have made a very important discovery. In particular they found that a kind of external clam was identical to the clam Tridacna maxima, genetically but differed significantly. As demonstrated by the analyzes, it was a new species. The clams were traditionally used for food, for decorating aquariums, creating tools and jewelery.

The preservation of the giant clam species requires recognition and proper assessment of their population. The reproduction of the new kind of clams the eggs and sperm meet outside in with water. This means that an area must be in large population to ensure that the eggs and sperm will meet.
