Abstract

ELECTRIC COMMUNICATION: FUNCTIONS IN THE SOCIAL BEHAVIOR OF EIGENMANNIA VIRESCENS by CARL D. HOPKINS 1) 2) (The Rockefeller University, New York, N.Y., USA) (With 10 Figures) (Rec. 15-VI-1973) Electric communication has evolved in certain fishes for the purpose of identification, for forming or maintaining social relationships, and for syn- chronizing behavior. Relatively little is known regarding this communication channel. Among several distantly related groups of fishes, electric signals originate in specialized electric organs, are transmitted as electric currents in water, and are received by specialized cutaneous electroreceptors.
