Cacite
Life on Earth is carbon based, so all animals with skeletons and shells use carbon. A more 'common' element used in skeletons and shells is calcium.
Mother of pearl is made from the shells of various molluscs , and is mostly various calcium carbonates. Go look at wikipedia.
The number of shells varies. The row number of the element is the number of shells. They don't really have names, but they're referred to by how many levels they are away from the nucleus.
The Cambrian Explosion, a period between about 540 and 530 million years ago when many major animal groups appeared in the fossil record. This is when animals first developed hard shells and skeletons, so they became much more easily fossilised. Nobody is quite sure what caused the Cambrian Explosion, but increased oxygen levels in the air after the melting of a huge ice age around 600 million years ago may have led to an increase in the size of animals in the oceans; in turn they developed skeletons and shells to support their larger bodies. The evolution of predators may have inspired prey animals to develop shells, as well. We do have fossils before the Cambrian Explosion, but these are simple, soft-bodied, small and rare, so the origins of animals are still shrouded in mystery.

Bivalves ( clams. mussels, scallops)
Oysters and mussels do not shed their shells. They are bivalve molluscs and their shells grow larger with age.
They eat mussels and other animals with shells.
Aragonite, a carbonate mineral.
I think its their shells.
Yes.
Dont know i was actually asking the same thing. I'd laugh if this is the best answer lol
Their shells grow as the organism grows
Mussels absorb carbon into their shells from the ocean water. The carbon is in the form of calcium carbonate, which mussels extract from the water to build their shells. When carbon dioxide in the atmosphere dissolves in the ocean, it forms carbonic acid, which can break down to release carbonate ions that mussels use to create their shells.
clams, oysters, or mussels
Yes, limestone is a sedimentary rock primarily made up of calcite and aragonite minerals, which are derived from the shells of marine organisms. Over time, these shells accumulate and are compacted to form limestone rock.
The dark blue clumps of oval shaped shells are called mussels.
