Giant Clam
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
The giant clam (Tridacna gigas) is one of the largest bivalve mollusks in the world, native to the shallow coral reefs of the Indo-Pacific region. Renowned for its impressive size—often exceeding a meter in length—and vibrant, symbiotic relationship with photosynthetic algae called zooxanthellae, the giant clam plays a vital role in reef ecosystems. It filters plankton from the water, contributes to reef building through calcium carbonate secretion, and hosts a diverse range of marine life.
