Giant Clams are the largest bivalve mollusks and weigh around 200kg on average. The specimen in this image is considered "small" compared to the largest ever recorded which measured a staggering 137 cm. Each giant clam boasts unique colours and patterns, as distinctive as human fingerprints. 
 
These fascinating creatures are filter feeders, drawing water in through one siphon and expelling it through another, extracting nutrients as the water flows through their system. Just like coral, they also share a symbiotic relationship with zooxanthellae, a tiny microscopic algae that live in their tissue. These algae not only provide the clams with their vibrant pigmentation but also supply energy through photosynthesis, much like their partnership with coral. And just like coral, these xoozanthellae give them their pigmentation.
 
However, like coral, giant clams are vulnerable to bleaching when faced with stressful environmental conditions. During bleaching events, they lose the stunning colors of their soft tissue, a sign of their fragile connection to their marine habitat.
