Scallop or clam?

that is very close ill get a better look at it tomorrow since lights are off but that is very close

 

the shell doesnt look exactly the same as far as i can see but the tentacles and pink color seem pretty accurate!

 

Chlamys hastata is a cold water species (tasty )

 

yea shell is different but your right the tentacles and pink are very close

 

is that implying that it cant be the one or just that they are good eating. or both lol

 

They are very tasty!

One could agree that this is a mussel, correct? If that is the case, species like perna perna, Perna canaliculus, and others from the Mytilidae family are good starting points for your identification.

Cheers.

 

thanks monti, ill those out to see if they look similar

 

Was my post that confusing? Sorry I was just zooming through quickly.. I'll slow down this time

Unless she has a cold water tank and got that from a cold water dealer it won't be the "one" she has.

Yes, they are tasty especially done in a ceviche

Your link is to Rosario Beach Marine Laboratory in Washington which is all about local cold water stuff I had a friend that went there Not to mention I have a shellfish poster on my wall at work and guess what is on it?

 

nope not a cold water tank so exact ID is still unknown, ill try my best to get better pics tomorrow

 

You might have to extract it to get a for-sure ID, lol. It's not a clam. There aren't any similar ones that would be attached like that. It's probably not a scallop, since essentially all of the species of Pectinidae show some radial sculpture (even though it can be much reduced in a few of the deep water species) and yours appears to be almost smooth. Your shell looks very compressed (thin), and I don't know of any mussels that are that thin which live in salt water. There are several oysters similar to yours, however, and some show no more sculpture than yours shows. If it's not an optical illusion, and the whole shell is very compressed, even the hidden part, then that's probably what it is. I can't think of a purple one offhand, though. Tricky business trying to ID bivalves by the outer edges, since most of the identifying characteristics are elsewhere, but maybe that will point you in the right direction.

You might use the genus Isognomum as a starting point.
