They make their own and add material to the edges to accommodate growth as needed

Mussels do not shed their shells. They are bivalves and all bivalves just grow larger by adding material to their shells as they get older.
No because a crustacean has a exoskeleton and a mussel has a shell
vitamins and minerals :)
Shell, mussel, mollusk.
if you mean the animal then, shell fish
They have a strong shell :)
Yes. It has a shell. Invertebrates have no backbone, vertebrates do. Invertebrates often have a hard external shell (like a mussel), or exoskeleton (like a crab), to protect them from predators.
no because it aproximetly grows with its shell so i belive it never does shed its shell but the average life span of a scorpion is 1-3 years so in that stage it probbly will lose its shell when it dies.
Mussels have a sort of exo-skeleton. Their shell.
A mussel is a shellfish - you have to pull the meat from the shell to eat it.
Shells are a kind of external skeleton The shells grow by adding new material to the edges as the animal inside gets bigger in this way the animal is protected by its shell all the time and does not have to moult or shed their shell.
