Clam identification

Just wondering if is a clam and if it is what species would you say it is?

Very cool. I want to say it is a type of oyster but I am not sure myself.

Looks like a tridachna dersera. But I may be wrong because I can’t see the shell very well. It looks smooth to me.

The mantle is very bright blue under actinic if it helps, but it seems not as expanded as most clams.

It may not be expanded because it is too much flow. It is definitely a clam because of the wavey shell. The blue mantle just solidified that.

It's a bivalve but not of the tridacna species. Possibly a type if oyster or common bivalve hitchiker

There’s some more close up pics, the mantle looks to be connected on the middle

Yeah nope not a tridacna. Second pic, tridacnas have patterned shells. Still a cool hitchhiker.

I agree with this. Definitely not in the tridacna

No I wasn’t thinking myself too, I wouldn’t think is a oyster to as normally they very pale in colour. Is just the bright colours and the small mantle that making me curious as never seen anything like it.

It’s called a Rock Oyster!

I can see the resemblance, wasn’t ware that oysters were photosynthetic.

 

[sixty_reefer]

Could it be a hippopus porcellanus or something similar?

As cool as that would be, it is not.

Just a wishful thinking [emoji23]

I believe they are azoox. This info might help

Nothing wrong with the oyster and they are very cool creatures themselves. Going on color to determine if it is photosynthetic isn't entirely accurate either. I have a huge black mussel of some kind that has purplish/blue lips (they are small) but is definitely a filter feeder since it greatly opens up at night and during the day is covered by a large yuma.

As always top info mate, this could be interesting really appreciated for the link just identified a clam that been googling for ages

It’s a jewel box clam or chama macerophylla apparently

Happy to help, you have some nice hitchhikers!

No not at all, I do like interesting and different species of all sorts, I was just thinking photosynthetic as the clam is very sensible to light changes like most normal healthy clams.
