How are mollusc shells formed?

As mollusks develop in the sea, their mantle tissue absorbs salt and chemicals. They secrete calcium carbonate, which hardens on the outside of their bodies, creating a hard shell. ... The mollusk continues to take in salt and chemicals from the sea and secrete calcium carbonate, which makes its shell grow even bigger.

What are the two portions of a mollusk shell called?

In humans the two clavicles, on either side of the anterior base of the neck, are horizontal, S-curved rods that articulate laterally with the outer end of the shoulder blade (the acromion) to help form the shoulder joint; they articulate medially with the breastbone (sternum).

What does the name gastropod mean?
