Its name, silverfish, comes from its silvery color and the fact that is resembles a fish. Silverfish's mostly rely on carbohydrates to survive that come from various natural sugars and starches. In urban environments, they will eat glue, paper of any kind including books, sugar, coffee and even clothing, making them quite a pest when they are able to make their way into homes.
They are known as the Featherbacks, or Featherfin Knifefishes, and Knifefishes. They are found in Southeast Asia and Africa. This is a small group of knife fish, with only ten species in four genera. These fish are generally smaller fish that inhabit freshwater or brackish environments.Although they swim in a manner similar to the Gymnotiformes, they are not closely related.hese are not true knife fish, but are actually in the order Perciforms, which are the 'perches' or 'perch-like' fishes. These are the Grey knifefish Bathystethus cultratus, the Blue knifefish Labracoglossa nitida, Collared knifefish or Finscale razorfish Cymolutes torquatus, and the Jack-knifefish Equetus lanceolatus.
