A silverfish (Lepisma saccharina) is a small, wingless insect in the order Zygentoma (formerly Thysanura). Its common name derives from the animal's silvery light grey color, combined with the fish-like appearance of its movements, while the scientific name (L. saccharina) indicates the silverfish's diet consists of carbohydrates such as sugar or starches.
