The Silverfish (Lepisma saccharinum) is a small insect in the Lepismatidae family. It is silver, but it is not a fish. It moves a bit like a fish.

The Silverfish is a wingless insect with a metallic silvery-grey body covered in scales. Its body is a squashed oval-shape that tapers (narrows) towards its tail. It has six legs and long thin antennae. It has two long appendages at the end of its tail, called cerci (one is called a cercus). It has two small compound eyes.
