Description
All right. I have realized that the basic molluscoid anatomy will have to go through certain changes, I decided against the idea of having the "anal trunk" terminating into the mouth, and I have to work on their respiration, I will probably move their gills inside the mantle in most species to have the "incurrent" and "excurrent" openings like seen here.The "sea beaks" got their name because they pinch in defense if their armor is not enough to scare away the predators. I have made one species with a thorn for extra defense too.
Some sea beaks will burrow in the sediment, securing themselves with their foot, and they will retract deep down to protect themselves.
Some will use cement to anchor themselves directly to a rock or coral reef.
The one on the left is the most primitive species which doesn't have the "beak" yet.

Well, this project has been in stage of hibernation for quite some time...

That's terrible! But it happens to me all the time...
I've recently begun reviving my own project for my book, albeit temporarily. I'm not going to approach writing all of that for a while.

Thanks! They need to be worked on further, I don't even know if I think this concept is good enough...

no, i was high on him at the time, don't mind 
um actually, what does the beak do?

Well, The beak is actually a paired gill operculum (kida like those plates that fish have on either side of their head), and the animal would pump water in and out by opening and closing it - I will have to do sime thinking about the species on the left, it could either have the operculi inside the shell, or it wouldn't have them at all, and I think the latter will take over...
The "beak", though previously a breathing aid, is very big in some species and the "clam" can usie it to bite potentioal predators. Funnily enough, immediatelly after I got this idea, I started thinking about making some predatory clams too, which would use their beaks to snatch prey, and they would then inject some digestive liquids inside it, so they can easily suck the nutrients out of it.
"Crocodile clam" what does that sound like?

that's cool. i didn't think this was an underwater animal xD i think that's why it's called clam, no?
spider clam? spiders do something similar, no?
👍: 0 ⏩: 1
Yeah it is a marine animal, that's why it's called "sea beak" in the picture
well, I was mainly reffering to the shape of its "jaws" - triangular and with serrated edge - you know, a crocodile clam!
And yeah, spiders do the same, but I guess the clam would have to have eight legs to be called a spider clam.
