Esocidae (fish)

   Luciidae, or Esocidae, is the pike and pickerel family of bony fishes. These fishes have an elongated, somewhat compressed, powerful body, with rather small cycloid scales, an imperfect lateral line; the head and snout prolonged and depressed, the mouth large and lower jaw longest. The mouth is filled with strong teeth, and these fishes are the fiercest carnivores of the fresh waters. The family is widely distributed in northern waters, and may be traced back to the Miocene Age.
