Molluscs
Soft-bodied animals, most of them protected by a shell: snails and slugs, clams and oysters with two shells, and squids and octopuses, whose shell is inside their body or gone. Most have a strong muscular foot to move on, and snails scrape their food with a tongue covered in tiny teeth. An oyster can make a pearl by covering a bit of grit or a parasite with layer upon layer of shell.
