Here in Indonesia you will find various species of giant clams. They differ in size and shape but they all have one thing in common – they are mesmerizing when watching it.

This enormous shellfish is the largest species of bivalve mollusc in the fossil record, and the heaviest of all the living molluscs. The shell is extremely thick and lacks bony plates; when viewed from above, each valve has four to five inward facing triangular projections

Usually their mantle is a mixture of brown, pink, blow red, green and yellow colour.

Giant clam lives in symbiosis with algae, which means that both organisms have benefits from the mutual life. Giant clam provides shelter and enough sunlight, while algae provide food via photosynthesis.

The Giant Clams live sedentary life. They reproduce by external fertilization. The clams expelling sperm and eggs into the ocean. And each clam can make sperm and eggs, but eject only one type at a time. Within just 12 hours the eggs become trochophores during the swimming stage. And just within a couple of days it will become a planktonic larvae and stays at this stage for one week. The larvae settles to the substrate, where it metamorphoses into a juvenile clam and find a suitable location on the ground and attach itself. And it will stay at that place through all their life and not move.

Giant clams can survive more than 100 years in the wild.
