  • The Conger has a dorsal fin that comes from the back of the pectoral fin and goes to the tip of the tail resulting from the fusion of the dorsal, caudal and anal fins.

  • It is a sedentary fish, and sometimes settles in sunken boats and ships.
  • It has a big mouth and thick lips that hide two rows of pointed teeth.
