Abalone

Abalone are a group of small to large (the most recognizable are large) that belong in the family Haliotidae. Abalone are eaten in every country which has an abundant population (of abalone). While abalone consumption certainly isn't rare, it is considered a luxury item generally. In addition to delicious  food, abalone shells are use as jewelry. Jewelry production can be dangerous because the dust created from grinding and cutting shells is dangerous. Abalone shells are very strong and is made up of calcium carbonate tiles stacked on each other and there is also a "clingy" protein substance between the layers of the shell, abalone use both of these to their advantage so that when struck the layers slide and the protein absorbed the energy.
