THE BAT FISH FAMILY 



138 Family Oncocephalidae (Ogcocephalidae, Malthidae) 

 The family of the bat fishes are related to the angler fishes, but they 

 have smaller mouths and depressed bodies which are covered with hard, 

 bony warts. All of the members of the family live in the tropical seas. 

 They walk along the bottom like toads and are distributed over the ocean 

 bottom from very shallow water to immense depths. The deep sea forms 

 are small and more or less degenerate. 



Five members of this family are known from the Hawaiian Islands.
