Abstract 

Marine mammal species that have complex learned systems of communication are fascinating from a comparative perspective, as these systems evolved under very different conditions from terrestrial species. However, they continue to attract speculation about human-like language, in sometimes misleading ways. Two recent papers* from a group called Project CETI, a non-profit explicitly named as an echo of SETI (Search for Extraterrestrial Intelligence), and with the stated aim of translating whale language, have brought these issues into sharp focus. The publication of both papers was coordinated with waves of headlines announcing boldly and without caveat, the discovery of human language features in the vocal communication of sperm whales. I will show that In both cases however the headlines were erected on claims that do not bear scrutiny. I will also argue that an overhyped focus on “translating” sperm whale communication into human language has led this large research project into errors, irresponsible claims, and reduced scientific credibility, while obscuring promising alternative interpretations.
