The products that are derived from invertebrates are the following:

1. food - crabs, lobsters, oysters, octopuses: all of these are invertebrates (meaning they have no spine) and are used as food

2. shell - seashells are invertebrates and their shells are used for various purposes

3. jewelry - shells are used as jewelry, as well as pearls coming from seashells

4. silk - silk comes from silkworms, which are invertebrates

I just wouldn't pick cotton, because you get cotton from a plant.
