Description
So here they are! Enjoy!I tried to throw in a few "bivalves" for good measure, but things might change
You can only see "capslug" variants (with two shells far apart) here, and two derived "hoodlslug" examples (the "Pseudocaretta" and "Quasitestudo")
The "hoodslugs" (the more "basal" forms are not displayed here) have two big shells that touch one another.
These "snails" include marine and freshwater (benthic) forms and a "quasitestudo" lineage with four pairs of "legs" and a "pseudocaretta" lineage with 4 pairs of "fins."
Both of these lineages retain the two-shelled body plan of their ancestors.
This [link] shows my older idea for "capslugs," "hoodlsugs," "quasitestudo," and "pseudocaretta." I will maybe return to those original designs for these four body plans, i'm still experimenting with these critters, after all, I have just made up my mind about their general internal anatomy. It will take some time to branch off from this point and come up with something that isn't terribly earth-like...
The most primitive "molluscoids" are not included here, they still don't have a "cephalized" body (they lack a distinctive "head"), but even though they're roughly circular in shape, they're not radially symetric, and this anatomical drawing: [link] is based on them. For the external anatomy of these primitive limpet-like forms, see the "crown of thorns" here: [link]

Thanks bro! I only hope you undrstand they are alien "gastropods" though!
I know these look too "converged" so I decided to try and do better job:

What do you think? (The "bivalve" idea is going to be merged with this new anatomy

Whoops, I responded to your questions before seeing this!
...Wow, this is awesome! I didn't have those in mind when you menioned "cylindrical" shells but this looks much better than what I had in mind! Well done!

No no need to apologize! These were created/updated yesterday and today they are all outdated again! How funny is that?
I am just about to finish the editting of a completely new anatomy of the "limpets, slugs, snails and kin" and then upload it. It shouldn't take too long, so stay tuned if you can! I'm sure you'll like them too!
This new idea is absolutely fresh, and I will yet have to create animals with the body plans similar to what you can see here, but also in line with the (now hopefully final) anatomy, and even that shouldn't take too long, it might be done either later today or tomorrow!

I love them! Cool idea for having double shells my favourites got to be the middle right one they all look so awesome

Thanks! the one you like is the "pseudocaretta." It lives in open water, it's very huge in comparison with most earthly molluscs, but i still don't know what it eats...

How big is it ment to be? It could is small squish
π: 0 β©: 2
Oh yeah! Now I see it! Sorry!
well, I guess the big "preudocaretta" could eat small squish, but I like to think that they would be more focused on soft-bodied invertebrates.
On the contrary, I think many squish would count these "molluscs" as a regular part of their diet.
One of the "clams" - If i keep that idea - will be large enough to snatch many big animals whenever it gets the chance, although it will live mostly from tiny bits of organic matter falling from above to the depths where it lives.

Cool so it would be like some of earths giant clams that drown humans on rare occasions? Awesome
π: 0 β©: 1
Yeah, but those clams just happen to close their shells when an unaware diver happens to stick one if his ligs inside them.
They are mere peaceful filter-feeders and don't have any benefit from drowning that stupid guy. XD
Not this one though. (alien seas are full of big bad evil vicious things!

60 - 90 cm for the big open water species maybe?
But as I'm thinking about it, I guess there could be some far smaller coral reef relatives of these, they would be only about 10 - 20 cm long and they would be true "sea parrots" in terms of color...
the "clams" - if I keep them - will probably be able to grow enormous in some instances, I am thinking of a small-car-ized one, about 3m in length(width) and 500 kg in weight, but i guess this big fella will live in the depths (=deep sea gigantism - japanese giant crab, the giant isopod...) and feed on the falling organic matter. i gouess it could ocassionally snatch an animal foolish enough to swim too close to it, and man, at this size it won't be limited to small prey!
But the majority of the "clams" will be of a far more "managable" size.
The "quasitestudo" could average at about 20 cm in length, but they could grow up to 45 cm long, but that would probably happen in an area devoid of terrestrial predators.
The "capslugs" and "hoodslugs" would be in this range too, maybe slightly smaller, 15 - 25 cm long, and the two "worm-like" individuals (one of which has the two shells evolved into two "cylinders" which come together when the "slug" retracts to protect itself from predators and the second one with cone-like shells (or just one of the shells) uses them to dig in the substrate) would be even smaller, mostly 10 - 15 cm long at max.
The limpet-like ones will be the smallest, only up to 5 cm in diameter, but some of them will have enormous spikes on the shell like the "crown of thorns" here: [link]

Sounds pretty awesome man are you going to sculpt any?

I am planning to sculpt all of these critters eventually!
