GIANT CLAM

As in above water, it is a war down there...

Here, a giant clam fights for its space in a crack amongst the corals...

We can see the whole outer shell of these clams, if they are found in sandy bottoms where they are not restrained by corals.

But this guy is not even able to fully open its mouth for feeding.

I have seen giant clams in shades of light brown or pale green.

But they seem to be most radiant in blue...

They are usually found in shallow waters and are sensitive to light and water movement.

Swim near and over it on a sunny day and they will most often retract inside...

Some divers have their octopuses (spare oxygen unit) freely dangling down while diving, and if they are careless and/or unlucky, their octopuses may be inadvertently trapped in the mouth of the clam...

Then, it is ooh ooh oooh...

I have also observed clams that stretch about a meter and half long...

This guy was about 40 centimeters...
