Clam

Clam

The clam gets only one chance to find a nice home. Once it fastens itself to a spot on a reef, there it sits for the rest of its life.clams achieve their enormous proportions by consuming the sugars and proteins produced by the billions of algae that live in their tissues. In exchange, they offer the algae a safe home and regular access to sunlight for photosynthesis, basking by day below the water's surface with their fluted shells open and their mulch-colored mantles exposed. They also use a siphon to draw in water to filter and consume passing plankton.
