Shells are usually composed of calcium carbonate formed by marine organisms like mollusks. The calcium carbonate is secreted by the organism and hardens over time to create the structure of the shell.
No, myriapods do not have a shell. Myriapods are a group of arthropods that include centipedes and millipedes, and they have an exoskeleton made of chitin to protect their bodies.
Grasshoppers do not have a shell like some other insects; instead, they have an exoskeleton made of chitin. They lack a coiled shell or a shell with two parts, as their body is segmented and covered by this hard outer layer. The exoskeleton provides protection and support, but it does not function like a traditional shell.
