What kind of clam is this?

Dentoid · 10-09-2007, 05:16 PM

Based on this photograph, what kind of clam would you say this is?

vdituri · 10-09-2007, 05:26 PM

That's my uncle Larry!
We thought he was dead!

He's a red-neck clam.

kyrie_eleison · 10-09-2007, 05:46 PM

A dead redneck? That's nothing new.

lcstorc · 10-09-2007, 05:50 PM

You can't tell by just the mantle. You need to also see the shell formation and several other criteria before even making a guess and even then there are exceptions.

kyrie_eleison · 10-09-2007, 05:54 PM

Lyn,

I already tried explaining that to Dent. It must be a Virginia thing. He's convinced that it's a crocea. I've had that thing for almost a year now and last I checked, croceas don't do well under PC lights.

DENT,

IT'S NOT IN THE COLOUR; YOU HAVE TO LOOK AT THE SHELL TOO. YOU NEED TO KNOW THAT FIRST.

lcstorc · 10-09-2007, 05:58 PM

There are actually a lot of things you have to look at. It's not just the shell either. It's a combination of factors and even then the experts sometimes have difficulty. I can look at my clam book when I get home and tell you what James Fatheree says about both. I don't have it with me at work though.

I have read James Fatheree's book and I attended his lecture at the most recent MACNA and am well aware of all these things.

First, this is not about proving someone wrong Ms. Kyrie, it's about wether or not this is a durasa clam or not based on the picture that you provided. It's as simple as that.

Secondly, I'm not convinced that it is a crocea, I am however, convinced that it is not a durasa based on the picture, mantle color and mantle pattern.

Thirdly, you haven't tried nor convinced me of anything. All you have said is that it's not a crocea since you have PC lighting and it hasn't died in your tank. You have not said why it's a durasa either!

Fourthly, what do you have against Virginians, are you really that narrow-minded?

Well Dentrite,

It's not a "durasa"; it's a derasa and that's how the rest of the country spells it too. I'm not a woman; I'm a man. You haven't seen its shell so you tell others that it's a "durasa" which it's not. SO, that 3 strikes.

It's my clam; why wouldn't I know? I've intentionally placed it in the location it's in for a reason. I may not be able to take care of fish as well as I'm able to take care of corals, inverts and bivalves but I can IDENTIFY AND SPELL the name of the species better than some people.

You're not smart for creating this poll since you DON'T KNOW what kind of tridacna it truly is and hopefully no one else votes on this topic because they will most likely realize that it's not what you claim since they haven't seen the shell.

BEELZEBOB · 10-09-2007, 06:57 PM

then show the damn shell!

you need more than the pic to even start. but, that would be the very first and solitary blue durasa i have ever seen.

and forgive kyrie, hes an anti-dentite!

i mean hell, y'all gotta prove it now.

GeeWizzItsMe · 10-09-2007, 08:40 PM

I am pretty sure that is not a derasa! Good job having success with what I think is a crocea/maxima under PCs!

lcstorc · 10-09-2007, 08:57 PM

Well no matter how many times I re-read the descriptions of both clams there is just not any way to make even a decent id based on the information given.
Based on the picture alone, I think it is a Crocea.
It actually looks very much like a Crocea in my tank except mine has a blue/green ring around the outside.
But inhalent syphon, shell shape, scutes, better definition in the mantle etc could easily convince me otherwise.
Derasa usually has a more striped appearance often with a thin ring around the edge of the mantle. Often they are a variation of creams and browns with a ring of blue or purple.
Croceas are very commonly found in blue or green but can be any color. They can have stripes spots or rings.

One of the biggest difference between these two clams is on the inhalent siphon.

Below are excerpts from "Giant Clams in the Sea and the Aquarium" by James Fatherree about the inhalent siphon of both.

"The Crocea inhalent siphon is ringed with numerous but very small tentacles which may be very finely branched or oddly shaped."

"The Derasa inhalent siphon is is almost always ringed with prominent tentackes that have numerous branches. However sometimes they'll have a mix of these larger, fancier tentacles and smaller unbranched and pointed ones, and then there are a few that may have only tentacles that don't branch at all. Oftentimes, some of their tentacles had an odd sort of club shaped ends as well."

If we throw the other types of Triacnids into the mix it becomes even more difficult to tell without a lot more information.

So, can we get more detailed pics?

I will say most of all though it looks like a happy clam. I'm not sure how much PC light you have or how far away the clam is but it does look happy.

kathywithbirds · 10-09-2007, 09:03 PM

play nice, now.

Can we see pics just to see it?
