The shells of shrimp, clams, and crabs are primarily composed of a biopolymer called chitin, which is a tough, flexible substance. In crustaceans like shrimp and crabs, the chitin is often mineralized with calcium carbonate, providing additional strength and rigidity. Clam shells, on the other hand, are mostly made of calcium carbonate in the form of aragonite or calcite, giving them their hard and durable structure. Together, these materials provide protection and support for these marine animals.

What is the difference between the body covering of the conch and the shrimp?
A conch shell is hard, cylindrical and is not jointed. A shrimp shell has many parts that move with the shrimp and provide protection. Additionally, the material that the shells are made of are entirely different. Conch shells are made primarily of a mineral called aragonite. Each layer of aragonite is reinforced by layers of protein. Shrimp shells are made of chitin, the same material insects exoskeletons, crab & lobster shells, and spiderwebs are made of.
Name for a hearty soup made with shellfish?
This could be cioppino, which is a shellfish and fish stew where the shellfish often are still in the shell.

A variation on this is bouillabaisse where the shellfish are out of the shell, making it easier to eat without making a big mess (but the mess is part of the fun!).
