Pirate Perch Family- 
            Aphredoderidae 
  A single living species is known for this family, which is of North 
American origin, and is confined to the fresh waters of the eastern United
States. The pirate perch is in the last surviving genus of the family 
Aphredoderidae. Another genus lived during the Oligocene or Miocene 
but is now extinct. 
  The trout-perch and cavefishes (Amblyopsidae) are distant cousins of 
the pirate perch. Like cavefishes, the pirate perch has its anus and uro-
genital apertures in the throat region; however, it lacks the adipose fin
of the trout-perch. 
  The pirate perch is a spiny-rayed fish with ctenoid scales bearing a 
single row of teeth along the exposed edges of the scales. The swim 
bladder is simple, and the pneumatic duct to the pharynx is lost (phy- 
soclist). There are 12 pyloric caeca.
