Tridacna species Clams are the only members of the Mollusk Family to possess the symbiotic algae, zooanthellae. This enables them to utilize natural sunlight as their energy / food source. Its this internal algae that minimizes their need to rely on filter feeding and is what gives their mantle the exotic colorations. There are actually nine species within this family of Giant Clams.
