Giant Clam
Tridacna crocea

Like corals, giant clams live in partnership with tiny plantlike algae (called zooxanthellae) that live inside the clams' tissues. And as with corals, the arrangement helps both creatures. The algae gain protection from grazing animals; the clams grow large with the benefit of food produced by the algae.
At home on reefs throughout the Indian Ocean, the South Pacific and parts of South Africa, giant clams live on shallow reef flats down to depths of around 66 feet (20 m). Below that, the algae they depend on to survive wouldn't have enough sunlight to grow.

Species Information:
Diet sugars and proteins produced by the algae living inside their tissues; tiny, drifting plants and animals filtered from the water.

The largest species, Tridacna gigas, can grow to 4.25 feet (1.3 m) long.

Western Pacific coral reefs, Indian Ocean and the Red Sea

Other clams and mussels, scallops, oysters;
Phylum: Mollusca;
Class: Bivalvia

Conservation Notes:
The giant clam, Tridacna gigas, is rare due to overharvesting by people. Giant clams are now being farmed, which can cut down on the numbers taken from the wild.

Cool Facts:

As their name implies, giant clams are the largest clams in the world. The largest grow more than four feet (1.2 m) long.

Once a giant clam settles into a place and begins to grow, it stays permanently attached to that spot for life.

This shot was taken through glass at the Seattle Aquarium.

Hi ManYee,

Was this taken through glass? It is quite a photo. Well done. I have a giant clam shell but had no idea what it would have looked like if still inhabited. Nice work

Evelynn : )

Hi Manyee,
Excellent picture!
I like so much the sharp and clear details got on the image, specially if shot through glass.
The texture and forms of the giant clamp are so beauty and delicate.
You built a great composition with all that these marine creatures and its bright colours.
Congratulations and thanks for share it.
My best regards,

Hello Manyee,
You should follow diving lessons:-)
Nice image. Must be a beautiful world...
Well done

Hi ManYee

A brilliant shot of this clam and considering that it was taken without the aid of a fill-in flash (or so the evidence seem to indicate) it makes it so much more special. Once again you've shown what a great photographer you are by capturing this magnificent aquarium shot with perfect details under rather difficult circumstances. Contrasts, colours, levels, and sharpness are well balanced.

Those iridescent spots all over the mantle lit up like little lights on a Christmas tree. You also managed to arrest perfect details of the tentacles (around the edges of the inhalant syphon at the centre of the clam) which normally tend to sway around and move with the flow of the water and thus become exceptionally difficult to freeze under these low light conditions. Just remember, even thought it is an aquarium shot, clams need water movement and normally the tanks that house these animals are specially adapted to provide to their needs. Tridacna crocea clams are usually found in the shallow areas near the shore where there's a lot of water movement.

Very well done and TFS.
Best regards

PS. I have so much catching up to do, but I'll be in touch. Talk to you soon MF.

Hi Manyee,
