Bright mantle and impressive size – look out for a bright tridacna on the sea bottom. It's not as difficult as it may seem at first glance.
Tridacna, or the maxima clam, lives at a depth of up to 100 meters and in shallow waters, too. So even if you are not a professional diver, when swimming in the Great Barrier Reef you will see this amazing creature.
Tridacna is an amazing bivalve mollusk long-liver, whose age can reach 300 years. Its shell is huge – up to one and a half meter in length, which is not surprising, as the clams themselves are not too small either. The weight of some species can be over 300 kilograms!
The shell valves are always open revealing the bright mantle of the mollusk, which is often blue, turquoise, brown, yellow or green in color. Yet, the shell itself looks quite plain, plastered with small shells and seaweed.
The clam passes seawater through itself and filters it, since it feeds on small mineral particles and unicellular organisms.
The residents of Australia and Oceania use tridacna for food and carve some simple household items from its shells.
