# The Gigas Clam: A Giant of the Seafloor with Exceptional Marine Value The Gigas clam (Tridacna gigas), often referred to as the giant clam, is one of the largest and most awe-inspiring bivalves in the world’s oceans. Native to the warm tropical waters of the Indo-Pacific region, this remarkable marine organism captivates both scientists and underwater enthusiasts with its massive size, vibrant colors, and ecological importance. ## What is a Gigas Clam? Tridacna gigas belongs to the family Tridacnidae—the giant clams—which are among the largest living bivalve mollusks. Reaching lengths of up to 1.5 meters (5 feet) and weighing over 220 kilograms (485 lbs), the Gigas clam is truly a marine giant. Its distinctive appearance features a thick, calcified shell with intricate ridges and striking patterns of blue, green, yellow, and white—often matching the colorful corals and reef environments it calls home.
