Fluted Giant Clam
Tridacna squamosaAlso known as Scaly Clam, Scaly Giant Clam
Fluted giant clams anchor themselves to shallow coral reefs, exposing their brilliantly colored, photosynthetic mantles to the tropical sun. These bivalves grow prominent, leaf-like flutes on their shells that provide shelter for small reef fish and invertebrates. By hosting symbiotic algae, they generate most of their own food while filtering organic particles from the passing current.

VU
Safe to observe at a normal distance while diving or snorkeling.
Highly vulnerable to illegal poaching for their shells and meat, as well as habitat destruction from climate change.
Never touch, anchor near, or disturb these clams; report any suspected poaching to local marine authorities.- Do Not Touch: Avoid touching the sensitive mantle tissue, which causes the clam to snap shut.
- Maintain Distance: Keep a respectful distance to prevent blocking the sunlight they need for photosynthesis.
- Watch for Spawning: Look for synchronized spawning events, which typically occur during spring high tides.
