| | An experiment in two-way communication in Orcinus orca L. |
 | | If there is any chance for such an interspecific communication, we postulate that it is with the killer whale (Orcinus orca L.), the most advanced species in the delphinid family as far as behaviour is concerned. |
 | | The subject of this experiment was a female killer whale, Orcinus orca, from the North-Atlantic ocean, named Gudrun. |
 | | She was caught in October 1976 off the southeast coast of Iceland and transported to the Dolfinarium in Harderwijk. |
