Minh what's your problem? Unless you're a gifted scientist who can tell what species that is just from a small pic, (and not many scientists would even speculate with out firsthand examination) leave the guy alone and quit knocking his hopes down. It looks like a maxima, and might very well be. Only time will tell.

Umm... Minh is a very well respected member of this and almost all other online BB's. He has a lot of experience and knowledge. As Minh stated, Tridacna clams can be identified is by the number, shape and symmetry of the ridges. In fact, those are basically the only way, other than DNA testing.
OK so it may not be a Tridacna. It does have more than 5 ridges. But it definitely has little green spots where a mantle would be growing. I have seen pictures of Crocea types with 6 ridges. Is that a possiblity?
Anyway, regardless, I still think its interesting. (more so then another snail).
Any idea what the growth rate is? (that is if it is a giant clam type)

I was trying to get him not to kill the snail. i guess i am too late.spfmatt said:
No, that is not a Tridacna clam. You got to realize that there are thousands of species of clams, only 7 or so are photosynthetic.
A clam that growing on a shell of a mobile snail is not a Tridacna clam.
Sorry if you are irritated, but what I wrote is not wrong.

It's what it's
I am counting at the very most 6 folds in the shell and what looks like blue or green colored zooxanthellae in the mantle. I would agree that it seems to be a hippopus as well. I am not an expert though and would like to see a better close up and also see it in a few months or a year to tell. Looks like a Tridacnid to me though. Freed

I'm with Minh on this one, that is definitely not a Tridacnid clam. The shape of the shell ridges is a dead giveaway.
Zooxanthellae is not blue or green, it is a golden brown colour. Colours in photosynthetic animals are produced by the animal itself. These pigments are in some cases no different to pigments produced by non-photosynthetic animals. The red of a flame scallop, the green in some mussels and some colours in tridacnid clams are all simply tissue pigments.

Please do a google search for "zooxanthellae colors" and you will notice that more articles state that zooxanthellae (most notably green, blue, red, yellow and orange) are responsible for the bright colors found in corals, sponges and clams. I am only passing on what I have known from past experience and what I read after doing a google search. I am not saying you are wrong but only backing up what I say with articles and facts. You may still be partly correct, though. Freed

I think that you should get that clam off the shell somehow if possible, or just get the hermit into a new shell so that the clam stays put in one area, you may get a chance to see the mantle ( if indeed it is a tridacnid ) open up.. However if it's a Hippopus as I'm voting on, it may not open up much more...
