Help identify this clam

[matt.moo4]

I've had this clam for about a year, and cannot remember what type of clam it is.

 

[braaap]

Crocea.

 

[KQuillan]

It's beautiful!

 

[TangerineSpeedo]

I believe it is of the clam variety of mollusk... From the species of "Alive and doing Awesome!"

A top down image would confirm identification. I am inclined to say Maxima or hybrid.

top down would be helpful! I agree that it could be a maxima, or a Noae if the eye spots are more random.
The fluting isn’t indicative of a crocea, and the mantle isn’t that of a derasa, Gigas or a squamosa. Regardless it’s beautiful

It is a beautiful and unusual Tridacnid. More detail pictures at various angle is needed for better ID
Can rule out Gigas or Derasa. Other common species are all possibility.

Love it!

Based on my expiriance looking at it, it is a noae. the shape of the shell is either a maxima or noae, but the mantel pattern is definitely a noae although it's not coming from Indonesia cause the pattern is not what I am familiar with looking through Indonesia noae's.

 

[OrionN]

The shape of the shell is not typical of Noae or Maxima which are more elongated. Shape of shell is more like Crocea or Squamosa. Scuttles can be seen in tank raise Crocea, but they are a lot closer to each other. Scuttles on this clam is more like that of a small Squamosa. Patterns on mantel is more typical of Squamosa, or Noae. It is not a Gigas or Deresa

These are images needed to properly ID this clam.

1. Clear image of mantel includes both opening and shape of the mantel fully expanded with clear image of the spacing between the two sides of the mantel.
2. Clear picture of the shells, include size of the shells.
3. Clear picture of the Basal opening

T Noae for sure

T. noae

 

[MarineandReef Jaron]

The shell looks very Squamosa-like to me though the color is unusual.

No matter what, it is a beautiful animal.

Shells can be deceiving, but the mantle folds and the pattern say otherwise. Maxima and noae will have similar “folds” (the way the mantle lobes sit on top of each other) but the teardrop pattern is the biggest factor. No other species has teardrops like noae. If we can see the byssal opening, that would help as well. I’m 99.9% sure it’s noae.
