Deresa or squammy?

[4ptbuck]

Can somebody id my clam. It was sold as a deresa, but now I am suspecting it is a squammy.

Thanks 4pts....

That's a Derasa Clam, although the mantle looks like a Squamosa. Derasa's have a smooth shell and Squamosa's have a tiered shell.

Looks like a squamosa to me. From the mantle and the shell not being smooth but having ridges.

Well, the gaping looks like a Dersa. However... the color and shell looks like a squamosa to me.

I say toss a coin.

 

[kfisc]

bet it could be a hybrid- looks like the pix in delbeek & sprung vol. I-

Second on hybrid

I third a Deresa / Squam hybrid . Also check out the second picture closeley it looks like some kind of snail up under the mantle which probably isnt friendly . "Scrape 'em off Jim".

Looks like a squammy with broken scutes.

Squamosa. Lack of proper calcium and alk can lead to a smooth shell.

Looks like a squammy with broken scutes.

Ditto

Actually the snail like things, in the second pic were clams. A half dollar size clam on the left and a small one to the right.

No consenus as to Squammy or Deresa? Hmm I don't feel so bad for asking.

Is there any other distiguishers or pics I could provide to help?

 

[4ptbuck]

I am not sure what you mean by smooth shell, It definately is not smooth and has scutes.

can u turn the clam so u can get a pic of the side of the shell dead on,out of the sand, and then get a pic of the byssal opening then ill tell u for sure

 

[4ptbuck]

mbbuna, do you mean 1 from each end?
One looking at the byssal, and the other at the hinge?

I'll get these next time I am there.

 

[mbbuna]

one of the byssal and one of the side,almost like the one above but turn the clam a little more and if it can be up out of the sand so we can see the full side and shape of the shell
